SQLDataSource Update Using Parameters Not Working
Jul 10, 2006
I'm passing a parameter to a stored procedure stored on my sqlserver, or trying to atleast. And then firing off the update command that contains that parameter from a button. But it's not changing my data on my server when I do so.
I'm filling a dropdown list from a stored procedure and I have a little loop run another sp that grabs what the selected value should be in the dropdown list when the page loads/refreshes. All this works fine, just not sp that should update my data when I hit the submit button.
It's supposed to update one of my tables to whatever the selected value is from my drop down list. But it doesn't even change anything. It just refreshes the page and goes back to the original value for my drop down list.
Just to make sure that it's my update command that's failing, I've even changed the back end data manually to a different value and on page load it shows the proper selected item that I changed the data to, etc. It just won't change the data from the page when I try to.
This is what the stored procedure looks like:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ALTER PROCEDURE [dbo].[UPDATE_sp] (@SelectedID int) AS
BEGIN
UPDATE [Current_tbl]
SET ID = @SelectedID
WHERE PrimID = '1'
END
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
And here's my aspx page:

I'm new to ASP and ASP.NET so I used the Wizards in Visual Web Deverlopment Express 2005 to build the following code:<asp:DetailsView ID="DetailsView" runat="server" DataSourceID="TracksDataSource"
Height="50px" Width="125px" AutoGenerateEditButton="True" AutoGenerateRows="False">
<Fields>
<asp:BoundField DataField="pk_trackID" HeaderText="pk_trackID" ReadOnly="True" SortExpression="pk_trackID" />
<asp:BoundField DataField="trackName" HeaderText="trackName" SortExpression="trackName" />
<asp:BoundField DataField="trackPath" HeaderText="trackPath" SortExpression="trackPath" />
<asp:BoundField DataField="lyrics" HeaderText="lyrics" SortExpression="lyrics" />
</Fields>
</asp:DetailsView>
<asp:SqlDataSource ID="TracksDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:connectionString %>"
SelectCommand="SELECT * FROM [Tracks] WHERE ([pk_trackID] = @pk_trackID)" UpdateCommand="UPDATE [Tracks] SET [trackName] = @trackName, [trackPath] = @trackPath, [lyrics] = @lyrics WHERE [pk_trackID] = @pk_trackID" >
<UpdateParameters>
<asp:Parameter Name="trackName" Type="String" />
<asp:Parameter Name="trackPath" Type="String" />
<asp:Parameter Name="lyrics" Type="String" />
<asp:Parameter Name="pk_trackID" Type="String" />
</UpdateParameters>
<SelectParameters>
<asp:ControlParameter ControlID="TracksListBox" Name="pk_trackID" PropertyName="SelectedValue" Type="String" />
</SelectParameters>
</asp:SqlDataSource> However, when I click Edit, change something, and then Update it doesn't update the database. However, if I remove the DataField bindings and use the AutoGenerateRows feature it works fine.

Hello all,
Ok, I finally got my SqlDataSource working with Oracle once I found out what Oracle was looking for. My next hurdle is to try and set the Update Command and Parameters dynamically from a variable or radiobutton list. What I'm trying to accomplish is creating a hardware database for our computers by querying WMI and sending the info to textboxes for insertion and updating. I got that part all working nicely. Now I want to send the Computer name info to a different table column depending on if it is a laptop or desktop. I have been tossing around 2 ideas. A radiobutton list to select what it is and change the SQL parameters or do it by computer name since we have a unique identifier as the first letter ("W" for workstation, "L" for Laptop). I'm not sure what would be easiest but I'm still stuck on how this can be done. I posted this same question in here a few days ago, but I didn't have my SqlDataSources setup like I do now, I was using Dreamweaver 8, it is now ported to VS 2005. Below is my code, in bold is what I think needs to be changed dynamically, basically i need to change DESKTOP to LAPTOP...Thanks for all the help I've gotten from this forum already, I'm very new to ASP.NET and I couldn't do this without all the help. Thanks again!
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:CAT %>"ProviderName="<%$ ConnectionStrings:CAT.ProviderName %>" SelectCommand='SELECT * FROM "COMPUTER"' UpdateCommand="UPDATE COMPUTER SET DESKTOP = :DESKTOP, TECH = :TECH, SERVICE_TAG = :SERVICE_TAG WHERE USERNAME=:USERNAME">

My compiler says that the line in bold below is illegal. The error msg I'm getting is: No overload for method 'select' takes '0' arguments. How can I correct this error and execute a SELECT?
protected void Button1_Click(object sender, EventArgs e)
{
SqlDataSource2.Select ();
}
protected void SqlDataSource2_Selected(object sender, SqlDataSourceStatusEventArgs e)
{string strReadyFirstName = e.Command.Parameters["@FirstName"].Value.ToString();string strReadyLastName = e.Command.Parameters["@LastName"].Value.ToString();
}
<asp:SqlDataSource ID="SqlDataSource2" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"

My total test page is shown below. I monitor the connections by SP_WHO2. Without the second call, connection pooling seems to be working, ie I refresh my browser repeately but the number of connections as seen from SP_WHO2 does not increase.
However, if I have the second call, every time I refresh the page at the browser, the number of connections increases by one. This is obviously not acceptable in a real world application.
I tried both Integrated Authentication (with no impersonation) and using a hardcoded service account. Both have the exact same results. In fact this test is not about multi-user yet, it is the same single user just refreshing the same page.
May I know what have I done wrong? All the documentation from Microsoft says close the connection after using it. In the case of SqlDataSource how do I close the connection?
Thanks

I want to update two tables in one page. So I created two FormView bound on two SqlDataSource controls, and I create a Update button on the bottom of page. And I writen some codes as below:
btnUpate_Click(object sender, EventArgs e){
sqlDataSource1.Update();
sqlDateSource2.Update();}
But, the records haven't updated.
In SqlDataSource2_Updating() function, I found all the parameters is null.
So, how to modify my code to do it.

Is
it possible to specify different parameters for the
select/update/delete stored procedures used by a sqldatasource? When I
'configure the datasource' it lists the different stored procedures for
each command, but when it comes to specifying the parameters it only
lets me do so for the select command. Is there another way to do this
for the other commands?
I have tried doing it manually in the aspx file (using the
DeleteParemeters etc), but I don't know how to reference a specific
cell in the selected row of the gridview for the controlparameter). Any
thoughts?

Hello I need help withsetting parameters for SqlDataSource
I have a simple program. I want display date from database on MS SQLSERVER from the table USERS only for current sing on user select by his login.
I save into this variable login current user: string @LOGIN = Context.User.Identity.Name;
I have already done with this way without SqlDataSource:
string login = Context.User.Identity.Name;
SqlConnection conn1 = new SqlConnection("server=CR\SQLEXPRESS;database=myData;integrated security=SSPI");
conn1.Open();
SqlCommand cmd1 = new SqlCommand(" SELECT IN_OUT.TIME_START, IN_OUT.TIME_END, FROM IN_OUT INNER JOIN USER ON USER.USER_ID=IN_OUT.RC_USER_ID where USER.LOGIN=@LOGIN", conn1);
cmd1.Parameters.Add("@LOGIN", SqlDbType.NVarChar, 50);
cmd1.Parameters["@LOGIN"].Value = login;
1.Parameters.Add("@LOGIN", SqlDbType.NVarChar, 50);
cmd1.Parameters["@LOGIN"].Value = login;
Now I don't know how to do with SqlDataSource, what I have to set in SqlDataSource1 yet
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:myConnectionString %>"
ProviderName="<%$ ConnectionStrings:myConnectionString.ProviderName %>" SelectCommand="SELECT IN_OUT.TIME_START, IN_OUT.TIME_END, FROM IN_OUT INNER JOIN USER ON USER.USER_ID=IN_OUT.RC_USER_ID where USER.LOGIN=@LOGIN">

I set up a sqldatasource based on a stored procedure which takes one parameter. The sqldatasrouce wizard generates the following code for the parameter below. The question is how do I value the DeptID parameter on the load of the form. I tried the following code in the load of the page, but get a null reference error:Me.SqlDataSource1.InsertParameters("DeptID").DefaultValue = Session("DeptID") <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FDConn %>" SelectCommand="GetTruckStatus" SelectCommandType="StoredProcedure"> <SelectParameters> <asp:Parameter Name="DeptID" Type="Int32" /> </SelectParameters> </asp:SqlDataSource> <radG:RadGrid ID="RadGrid1" runat="server"> </radG:RadGrid>

I need to do some select & update from VB code behind a web page. Using VS2005, ASP.NET.
To me, the most logical approach would be to use a SqlDataSource. I can select the connection string, predefine select, insert and update queries and call the select(), and other commands from this control.
I need to use parameters in the queries but I cannot connect parameters straight to controls, I need to do it from VB. But nowhere can I find how to set the parameter values from code. I can find all kind of examples from VS2003 or using SqlCommand, but it should be possible from this control as well, but the help documentation is very poor in this respect.
Please provide me with some example.
Kind regards

The Folowing code is not working anymore. (500 error)
Set objRS = strSQL1.Execute
strSQL1 = "SELECT * FROM BannerRotor where BannerID=" & cstr(BannerID)
objRS.Open strSQL1, objConn , 2 , 3 , adCmdText
If not (objRS.BOF and objRS.EOF) Then
objRS.Fields("Exposures").Value =objRS.Fields("Exposures").Value + 1
objRS.update
End If
objRS.Close
The .execute Method works fine
strSQL1 = "UPDATE BannerRotor SET Exposures=Exposures+1 WHERE BannerID=" & cstr(BannerID)
objConn.Execute strSQL1
W2003 + IIS6.0
Pls advice?

Hello,
I have a SqlDataSource that is not doing my inserts properly. even if the user is logged in (UserName!=""), it always inserts a null in the UserName field.
SqlDataSource:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:imLLConnectionString %>" DeleteCommand="DELETE FROM [tblDiaryEntries] WHERE [DiaryEntryID] = @DiaryEntryID" InsertCommand="INSERT INTO [tblDiaryEntries] ([DiaryEntry], [Subject], [EntryDate], [UserName]) VALUES (@DiaryEntry, @Subject, @EntryDate, @UserName)" SelectCommand="SELECT [DiaryEntry], [Subject], [EntryDate], [DiaryEntryID], [UserName] FROM [tblDiaryEntries] WHERE [UserName]=@UserName" UpdateCommand="UPDATE [tblDiaryEntries] SET [DiaryEntry] = @DiaryEntry, [Subject] = @Subject, [EntryDate] = @EntryDate WHERE [DiaryEntryID] = @DiaryEntryID"> <DeleteParameters> <asp:Parameter Name="DiaryEntryID" Type="Int32" /> </DeleteParameters> <UpdateParameters> <asp:Parameter Name="DiaryEntry" Type="String" /> <asp:Parameter Name="Subject" Type="String" /> <asp:Parameter Name="EntryDate" Type="String" /> <asp:Parameter Name="UserName" Type="String"/> <asp:Parameter Name="DiaryEntryID" Type="Int32" /> </UpdateParameters> <InsertParameters> <asp:Parameter Name="DiaryEntry" Type="String" /> <asp:Parameter Name="Subject" Type="String" /> <asp:Parameter Name="EntryDate" Type="String" /> <asp:Parameter Name="UserName" Type="String"/> </InsertParameters> </asp:SqlDataSource>
and from code behind, i do:
protected void Page_Load(object sender, EventArgs e) { if (!this.IsPostBack) { SqlDataSource1.SelectParameters.Add("UserName", this.User.Identity.Name); SqlDataSource1.InsertParameters.Add("UserName", this.User.Identity.Name); } }
Any ideas/suggestions? Thanks!

The problem I'm having is described below all this code.---------------------------------------------------------My content page has a SqlDataSource: <asp:SqlDataSource ID="sqlGetUserInfo" runat="server"
ConnectionString="<%$ ConnectionStrings:RemoteNotes_DataConnectionString %>" SelectCommand="SELECT [UserFirstName], [UserLastName] FROM [Users] WHERE ([UserGUID] = @UserGUID)"
onselecting="sqlGetUserInfo_Selecting"> <SelectParameters> <asp:Parameter Name="UserGUID" Type="String" /> </SelectParameters> </asp:SqlDataSource> -----------------------------------------------------Inside my OnSelecting event, I have: protected void sqlGetUserInfo_Selecting(object sender, SqlDataSourceSelectingEventArgs e) { sqlGetUserInfo.SelectParameters["UserGUID"].DefaultValue = Membership.GetUser().ProviderUserKey.ToString(); } ---------------------------------------------------------------------And, inside my Page_Load, the relevant code is: //String strUserFirstName = ((DataView)sqlGetUserInfo.Select(DataSourceSelectArguments.Empty)).Table.Rows[0]["UserFirstName"].ToString();
DataView dvUserDetails = (DataView)sqlGetUserInfo.Select(DataSourceSelectArguments.Empty);
if ((dvUserDetails != null) && (dvUserDetails.Count > 0)) { DataRow drUserInfo = dvUserDetails.Table.Rows[0]; lblHelloMessage.Text = "Hello, " + drUserInfo["UserFirstName"].ToString() + ((drUserInfo["UserLastName"].ToString() == "") ? "" : " " + drUserInfo["UserLastName"].ToString()); } ---------------------Now, here's the problem. My "if" statement is never executing because "dvUserDetails" is null. However, when I break the execution and put awatch on the actual Select() statement, it shows a DataView with the correct return rows! You can see the commented line where I tried tobypass the DataView thing (just as a test), but I get an object reference is null error.The weird thing is that it was working fine one minute, then started getting "funky" (working, then not, then working, then not), and now it just doesn't work at all. All thiswithout me changing one bit of my code because I was checking out some UI flow and stopping and restarting the application. I've tracked downthe temporary files directory the localhost web server runs from, deleted all those files, and cleaned my solution. I've even triedrebooting, and nothing seems to make it work again.My relevant specs are VS2008 9.0.21022.8 RTM on Vista Enterprise x64.

I am writing a pgm that attaches to a SQL Server database. I have an Add stored procedure and an Update stored procedure. The two are almost identical, except for a couple parameters. However, the Add function works and the Update does not. Can anyone see why? I can't seem to find what the problem is...
This was my test:
Dim cmd As New SqlCommand("pContact_Update", cn)
'Dim cmd As New SqlCommand("pContact_Add", cn)
Try
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add("@UserId", SqlDbType.VarChar).Value = UserId
cmd.Parameters.Add("@FirstName", SqlDbType.VarChar).Value = TextBox1.Text
[...etc more parameters...]
cmd.Parameters.Add("@Id", SqlDbType.VarChar).Value = ContactId
cn.Open()
cmd.ExecuteNonQuery()
Label1.Text = "done"
cn.Close()
Catch ex As Exception
Label1.Text = ex.Message
End Try
When I use the Add procedure, a record is added correctly and I receive the "done" message. When I use the Update procedure, the record is not updated, but I still receive the "done" message.
I have looked at the stored procedures and the syntax is correct according to SQL Server.
Please I would appreciate any advice...

Hi,How do I set the parameters of an SqlDataSource programatically?I have tried the following...dsDraftBudgetPI.SelectParameters.Add(new Parameter("@person_id", TypeCode.Int32, pID.ToString()));But that didn't work. I already have the parameter defined at design time so I don't need to create one I just want to set its value and then bind it to a ListBox to display the result.Thanks,Scott

Hello!
I am pulling my hair out over this latest problem. I'm trying to do a simple SQL SELECT statement by taking values from textboxes and inserting them into the WHERE part of the statement. I'm using MySQL and have to use ? prefix for all inserts, that I have working by the way. Now for some reason I cannot get the values from the text boxes to replace the prefixes! Here is my code:
private void submitLogin(object source, EventArgs e) {
if (isPassword(password.Text.ToString()) && isEmail(username.Text.ToString()))
{
ValidateCustomer.SelectParameters["c_email"].DefaultValue = "fish";
ValidateCustomer.SelectParameters["c_password"].DefaultValue = "cakes";
test_label.Text = ValidateCustomer.SelectCommand.ToString();
}
else {
test_label.Text = "Username or Password Incorrect";
}
}
<asp:SqlDataSource runat="server"
ID="ValidateCustomer"
ProviderName="System.Data.Odbc"
ConnectionString ="<%$ connectionStrings:MySQLDatabase %>"
SelectCommand ="SELECT * FROM customer_details WHERE (Customer_Email = ? AND Customer_Password = ?)">
<selectparameters>
<asp:parameter name="c_email" type="String" />
<asp:parameter name="c_password" type="String" />
</selectparameters>
</asp:SqlDataSource>
I have omitted obvious code. The test label, when updated, shows the SQL statement but with the ?. I also use controlparameters that took the values directly from the textboxes but again this did not work. I'm really stuck with this one. Your help is much needed!
Cheers
Dan

Can you access the values within sqldatasource parameters
programmatically? I have tried to reference them in the following
ways without any luck.
-SqlDataSource_Contacts.UpdateParameters("original_user_id")
-SqlDataSource_Contacts.UpdateParameters("original_user_id").ToString
-SqlDataSource_Contacts.UpdateParameters("original_user_id").DefaultValue
-SqlDataSource_Contacts.UpdateParameters("original_user_id").DefaultValue.ToString
-SqlDataSource_Contacts.UpdateParameters.Item("original_user_id")
-SqlDataSource_Contacts.UpdateParameters.Item("original_user_id").ToString
-SqlDataSource_Contacts.UpdateParameters.Item("original_user_id").DefaultValue
-SqlDataSource_Contacts.UpdateParameters.Item("original_user_id").DefaultValue.ToString

I have a GridView bound to a SqlDataSource. On page load I would like to programmatically specify a SelectParameter value based on the role of the user. This SelectParameter will be used in my WHERE clause. The closest post I can find is http://forums.asp.net/thread/1233258.aspx but no answer was posted.
What code would I use to modify a SelectParameters value? Is it possible to reference a parameter by name (SqlDataSource1.SelectParameters["usertype"]) or does it have to be by index? (SqlDataSource1.SelectParameters[0])
Alternatively, perhaps I'm going about this in the wrong way, is there a better way to have dynamic GridView content based on the role of the user?
Thank you very much for your help.

If I have a lot of dropdowns of similar type but only differ in one field, is there a way to set parameters so that the dropdownlist can specify what the parameter values are?
For example dropdowns: expenseaccount, incomeaccount, assetaccount
SqlDataSource:
SelectCommand="select accountid,accountname from accounts, accounttypest where accounts.accounttypeid=acounttypes.accounttypeid and accounttypes.accounttypename=? order by accountname"
<SelectParameters>
<asp:Parameter Name="accountTypeName" Type="string" />
</SelectParameters>
-------
I would like expenseaccount to be able to specify "EXPENSE", incomeaccount to specify "INCOME", etc...
Or is sqldatasource reusage bad practice?

I have a sqldatasource in a wizard. When I click the finishbutton in the wizard I want to insert some values (from textboxes, dropdownlists in my wizard) into a mysql-database. For this I use parameters, I add some values in the design mode and some in codebehind. The parameters in codebehind are added perfectly but the other parameters in designmode (name, email) just inserts null. Why? My datasource: <asp:SqlDataSource
ID="dsInsert"
InsertCommand="INSERT INTO tbltest (name, email, city) VALUES (?name, ?email, ?city)"
runat="server"
ConnectionString="<%$ ConnectionStrings:conn %>"
ProviderName="MySql.Data.MySqlClient">

<asp:FormParameter Name="?email" ConvertEmptyStringToNull="true" Type="string" FormField="email" />

A really (I guess) simple problem: DataView with SqlDataSource <asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1"> <ItemTemplate> <asp:Label ID="id" runat="Server" Text='<%# Eval("ID")%>' /> </ItemTemplate> </asp:DataList> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:MyConnectionString %>" SelectCommand="GetItem" SelectCommandType="StoredProcedure"> </asp:SqlDataSource> Now, what I have to do is to pass two parameters to the stored procedure: 1) ProviderUserKey2) Int ValueBut the question becomes "how"?Even if I define: <SelectParameters> <asp:Parameter Name="I_GUID" /> <asp:Parameter Name="I_TYPE" Type="Int32" DefaultValue="1" /> </SelectParameters>I need to set the parameters from code behind.... Thanks for any suggestions Adam

I am using a SQLDataSource with Stored Procedures. The Select, Insert and Update all work well. However I cannot get the delete to work. My stored procedures are tested and verified and the parameter names are the same as the source columns. When I try to run the delete an error that the stored procedure expects the parameter @locationStationId, however this value passes properly for the Update command?!? I tried to change the parameter to original_locationStationID to pass the original value, however this result in Null being passed for the parameter.
I cannot understand why this works for Update and passes the location ID, but will not work for DELETE. Can anyone shed any light onto the matter?
Thanks.OldValuesParameterFormatString="original_{0}" UpdateCommand="spUpdateLocation" UpdateCommandType="StoredProcedure"
DeleteCommand="spDeleteLocation" DeleteCommandType="StoredProcedure">
<DeleteParameters>
<asp:Parameter Name="locationStationId" Type="String" />
</DeleteParameters>
<InsertParameters>
<asp:Parameter Name="locationStationId" Type="String" />
<asp:Parameter Name="locationType" Type="String" />
<asp:Parameter Name="locationName" />
<asp:Parameter Name="division" Type="String" />
</InsertParameters>

I have an SQLDataSource. The SQL is
SELECT UserName, Category, ItemDescription, Size, Price, Reduce, Donate, Sold, ItemNumber, SoldDate, SoldPrice, PrintedFROM Tags WHERE (Printed = @Printed1 OR Printed = @Printed2 OR Printed = @Printed3) ORDER BY ItemNumber DESCThe bit field "printed" can be NULL, True or False.In the Selecting event of the SQLDataSource I have the following to show ALL records. But it does not work. If I remove these parameters it show ALL records.
e.Command.Parameters("@Printed1").Value = Nothing 'ASP.NET 2.0 using Visual basice.Command.Parameters("@Printed2").Value = Truee.Command.Parameters("@Printed3").Value = False
What am I doing wrong???
Thanks

CancelSelectOnNullParameterHi,Suppose I have a SQLDataSource with a
SelectCommand="SELECT * FROM STOCKS WHERE USER=@USER ORDER BY STOCK_NAME"
and @USER is set as a session parameter. No problem till this part, but in some postbacks, I wish to add a new WHERE criteria to my SQL, so I do:DSSQL.SelectParameters.Add("@STOCK_NAME", "ABC123");
DSSQL.SelectCommand = DSgvStoklar.SelectCommand.Replace(" ORDER BY ", " AND STOCK_NAME LIKE @STOCK_NAME+'%' ORDER BY ");
gridViewDS.DataBind();
and wish that my SelectCommand is modified and a new parameter is added.
The SQL is modified, however -I guess- new parameter is not added, so I get "Must declare the scalar variable "@STOCK_NAME" error.
How can I solve, any ideas?

I have a sqlDatasource with 3 parameters based on the input of 3 text boxes on the page. The datasource returns sales details for a company based on a from and to date. I am attempting to set the value of the 3 parameters in the Selecting event of the datasource control but I'm not getting any data back. If I set the values literally then I get data back. Also when I step through the code I can see the 3 parameters getting their values from the textboxes and the drop down list as they should. This is driving me insane as I'm new to .net and just can't see what is stopping me retrieving the data when using the form fields to set the datasources parameters. Below is the aspx and the code behind for the page. Thanks in advance for any help. aspx..... <%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="LabelSales.aspx.cs" Inherits="LabelSales" Title="Untitled Page" %><asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server"> <asp:SqlDataSource ID="SqlDataSourceSales" runat="server" EnableCaching="false" ConnectionString="<%$ ConnectionStrings:streetwisedigitalConnectionString %>" SelectCommand="DL_GET_SALES_BY_LABEL" SelectCommandType="StoredProcedure" OnSelecting="SqlDataSourceSales_Selecting" > <SelectParameters> <asp:Parameter Name="fromDate" /> <asp:Parameter Name="toDate" /> <asp:Parameter Name="label" /> </SelectParameters> </asp:SqlDataSource> <asp:SqlDataSource ID="SqlDataSourceLabels" runat="server" SelectCommand="select label_id, label_name from dl_label order by label_name asc" ConnectionString="<%$ConnectionStrings:streetwisedigitalConnectionString%>"> </asp:SqlDataSource> <div> <table> <tr> <td>Start Date: </td> <td> <asp:TextBox ID="FromDate" Runat="server" Width="70"/> <asp:Button ID="btnFrom" Runat="server" Text="..."

I’ve got the following piece of ASP code, which updated a
table through the standard edit/update command filed options.
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$
ConnectionStrings:CAT_SYSTEMConnectionString %>"
OldValuesParameterFormatString="original_{0}"
SelectCommand="sp_diplomaViewQualifications"
UpdateCommand="UPDATE
PsnQualifications SET quantity=@quantity WHERE rowstatus=1 and
qualId=@original_qualId"
DeleteCommand="UPDATE
PsnQualifications SET rowStatus=0, lastUpdateOn=getdate(), lastUpdateBy=@createdBy
WHERE rowstatus=1 and qualId=@original_qualId"
SelectCommandType="StoredProcedure">
<UpdateParameters>
<asp:Parameter Name="original_qualId"
/>
<asp:Parameter Name="quantity"
/>
</UpdateParameters>
<DeleteParameters>
<asp:Parameter Name="original_qualId"
/>
<asp:Parameter Name="createdBy" DefaultValue="TEST"/>
</DeleteParameters>
<SelectParameters>
<asp:Parameter Name="masterKey"
/>
</SelectParameters>
</asp:SqlDataSource>
My problem is that I need to pass the contents
of the VB variable ‘createdBy’ into the DeleteParameters option.
This is defined in the code as: Dim createdBy As String = getUserLoginName(Me.Page)
How do I pass this into the update and/or delete part
of the command field on the ASP page?

hi,
i am using a sqldatasource with a formview that has three stored procedures associated with it. when i update a record in my formview, i need to increase two parameters that are displayed as labels in the formview by their value plus one.
i can't figure out how to increase the value in the stored procedure, or using the codebehind, or with some script in the html. any solution works for me. any suggestions?
if i can figure out how to increment one of my fields, i can use the same logic for the other. below is an example of what i am trying to do.
in my formview i have three fields: Count, Rate, Price. Count is a label, Rate and Price are editable textboxes. once i commit the update for the values of Rate and Price, i need the value of Count to increase by 1, and then have that value updated in the data base along with the new values for Rate and Price.
is there a way to do this in the codebehind, or in my stored procedure?
i am using Asp.Net 2.0, vs2005, and sql server.
any help is greatly appreciated. thank you.

Hi,
I'm having an issue trying to send parameters to a SQLDatasource object. I"m creating it in code (and I need it to stay there) I have determined that the stored procs called with no parameters work fine. I start having problems when I have any parameters. Interestingly, it doesn't crash. It just fails to run (the onselected event never fires).
dsUser is a protected SQLDatasource property
repMain is a repeater on the aspx sheet
lstUser is a stored proc with one varchar(10) parameter called cSort
Here is my current code that will result in no called to StatementCompleted and no data. Pull cSort parameter from the proc and it works just fine. Obviously I'm setting it wrong.
string cSelect = "dbo.lstUser";
dsUser = new SqlDataSource();
dsUser .ConnectionString = GetConStr();
dsUser .SelectCommand = cSelect;
dsUser .SelectParameters.Add( "cSort", TypeCode.String, "" );
dsUser .Selected += StatementCompleted;
repMain.DataSource = dsUser ;
TIA,
Nick Hustak
