Programmatically Loop Through Sqldatasource - Which Event To Place It In...to Get The Right Order....

Mar 7, 2008

Hello,  I want to loop through the first 10 records that are showing in a gridview with several pages that is populated by a sqldatasource.  I can loop through the sqldatasource and get the list of values, but I'm doing something wrong because the 10 records it prints out are not the same 10 records the user sees in the gridview...They can click a search button which changes the sort, and they can click on the column headings to change the sort order.

Where's the best place to put the looping code?  I need the result to be the same as what the users sees. 

  1        Protected Sub GridView1_Sorted(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.Sorted
2            Dim i As Integer = -1
3            Dim sTest As String = ""
4            Dim vwExpensiveItems As Data.DataView = CType(SqlDataSource1.Select(DataSourceSelectArguments.Empty), Data.DataView)
5   
6            'Loop through each record
7            i = -1
8            For Each rowProduct As Data.DataRowView In vwExpensiveItems
9                i = i + 1
10               'Output the name and price
11               If i > 9 Then
12                   Exit For
13               End If
14               sTest = rowProduct("employeeid")
15               Response.Write("RowSorting " & i.ToString & " [" & sTest & "]<br>")
16           Next
17       End Sub

I have a table called Table1 where I have five fields like Tableid, Processigndate, Amount, remainingCollectonCount and Frequency. All total I have more than 5Lacs records.

Now I need to fill up another table Called FutuecashFlow taking the records from Table1. There will be also five Columns like FutureCashflowid, Table1id, Processigndate, Amount.

Now the condition is that if the remainingCollectonCount =6 and the frequency is 12 then there will be the 6 entries in the futurecasflow table where the prcessign datae wille be addeed by 1 month.

For example Table1
Tableid, Processigndate Amount remainingCollectonCount Frequency
1 2014-02-15 48 8 12

the future cash flow table the prcessing date column will be shown in the following way

Processigndate
2014-03-15

Creating SQLDataSource Programmatically?

Apr 17, 2007

Hello. Im trying to create an SQLDataSource control programmatically. I need to do this because I want to do some stuff on my MasterPage's 'Page_Init' event.
 heres my code (Master.master.vb): Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
lblUser.Text = Page.User.Identity.Name

Dim PUser As New ControlParameter
PUser.ControlID = "lblUser"
PUser.Name = "LoginName"
PUser.PropertyName = "Text"
PUser.Type = TypeCode.String
PUser.DefaultValue = Page.User.Identity.Name

Dim SQLDS_Login As New SqlDataSource
SQLDS_Login.ID = "SQLDS_Login"
SQLDS_Login.ConnectionString = "I put conection string here. How do I use the one on my web.config?"
SQLDS_Login.SelectCommand = "SELECT [LoginID], [LoginName], [Role], [Status] FROM [myLogin] WHERE ([LoginName] = @LoginName)"
SQLDS_Login.SelectParameters.Add(PUser)
SQLDS_Login.SelectCommandType = SqlDataSourceCommandType.Text

GridView1.DataSource = SQLDS_Login
GridView1.DataBind()

End Sub
 
When i run, i get this error message:
The SqlDataSource control 'SQLDS_Login' does not have a naming container.  Ensure that the control is added to the page before calling DataBind.
 I never had any problem with Inserts, Updates and Deleting, but I have never made it work for Select when doing it programmatically.
Can you help me with this?

Programmatically Specify SqlDataSource Parameters

Apr 27, 2006

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.

Refresh An SQLDataSource Object Programmatically

Oct 27, 2006

Background - I have a page that uses a numeric value stored in a Session object variable as the parameter for three different SQLDataSource objects, which provide data to two asp:Repeaters and an asp:DataList.  Also, in the Page_Load, I use this value to to seed a stored procedure and an SQLDataReader to populate several unbound Labels.  This works fine.  In addition, I have a collection of 6 TextBoxes, an unbound Listbox, and two Buttons to allow the user to do searching and selection of potential matches.  This basically identifies a new numeric value that I store in the Session variable and PostBack the page (via one of the buttons).  This also works fine.Problem - I have been tasked with taking a different page and adding six textboxes to collect the search values, but to post over to this page, populate the existing search-oriented TextBoxes, adn programmatically triggering the search.  Furthermore, I have to detect the number of matching records and, if only 1, have the Repeaters and DataList display the results based on the newly selected record's key numeric value, as well as populating the unbound Labels.  I have managed to get all of this accomplished except for programmatically triggering the Repeaters and DataList "refresh".  These controls only populate as expected if a button is clicked a subsequent time, which makes sense, since that would trigger a PostBack and the Page_Load uses the new saved numeric key value from the Session.My history in app development is largely from Windows Forms development (VB6), this is my second foray into Web Form dev with ASP.NET 2.0.  I am willing to acceptthat what I am trying to do does not fit into the ASP environment, but I have to think that this is something that has been done before, and (hopefully) there is a way to do what I need.  Any ideas, oh great and wise Forum readers? *smile*

Jul 3, 2007

 Would someone be so kind as to save me from getting balder through pulling my hair out.
My aim is to extract data from a database using SQLDataSource, then edit the data and update the database using the SQLDataSource.
I have achieve the problem of retrieving the data from the sqlDataSource:DataView openRemindingSeats = (DataView)SqlDataSource2.Select(DataSourceSelectArguments.Empty);        //Int32 openRemindingSeats = SqlDataSource2.Select(DataSourceSelectArguments.Empty), DataView;
        foreach (DataRowView rowProduct in openReminding)        {            //Output the name and price            lbl_NumOfSeatsLeft.Text = rowProduct["Remaining"].ToString();

Within the sqlDataSource the sql code is as follows:SELECT [refNumber], [refRemaining] FROM [refFlights] WHERE ([refNumber] = @Number)
So at the moment my problems is being able to edit and update data to the same SELECTed data.Thank you for any help that you might have...

How To Programmatically Construct The UpdateCommand For SqlDataSource

Aug 1, 2007

Hi, All
I'm using Gridview and SqlDataSource to dynamically display the contents in different tables, as followed:
<%   dataSource.ConnectionString = System.Configuration.ConfigurationSettings.AppSettings["connectionString"];   dataSource.SelectCommand = "SELECT * FROM " + tableName;   gridView.DataBind();
   dataSource.UpdateCommand = "";%>
<asp:SqlDataSource ID="dataSource" runat="server"></asp:SqlDataSource><asp:GridView ID="gridView" runat="server" DataSourceID="dataSource" AllowPaging="True" AllowSorting="True" AutoGenerateEditButton="True" BorderColor="Silver" BorderStyle="Solid" BorderWidth="1px" CellPadding="3" PageSize="20" DataKeyNames="ID" OnRowDataBound="tableGridView_RowDataBound">    <HeaderStyle BackColor="#C0C0FF" />    <AlternatingRowStyle BackColor="#C0FFC0" /></asp:GridView>
The datasource take the "tableName" as argument to determine which table to display. My problem is I can't figure out a way to programmatically construct the UpdataCommand for the SqlDataSource. I try to get the field names from the HeaderRow, but all the cells are empty in this row.
Does anyone know what causes the problem or how to construct the UpdateCommand properly. Thanks!

Using SqlDatASource Programmatically - Output Parameters

May 13, 2006

I am using SqlDataSource programmatically in my data access layer - mainly for convenience but it does generally work fine with no obvious performance issues.
The problem I have is with getting back an output parameter. I have an insert-type stored procedure (in Sql Server 2005) operating on a table with an identity column as the primary key:
ALTER PROCEDURE [dbo].[InsertAlbum](@ArtistID int, @Title nvarchar(70), @NewID int OUTPUT)ASDECLARE @err intINSERT INTO dbo.ALBUMS (ARTISTID, TITLE)VALUES (@ArtistID, @Title)SELECT @err = @@error IF @err <> 0 RETURN @errSET @NewID = SCOPE_IDENTITY()
This works fine when run from Sql Server Management Studio and @NewID has the correct value.
My data access code is roughly as follows:
dsrc = New SqlDataSource()dsrc.ConnectionString = ConnectionStringdsrc.InsertCommand = "InsertAlbum"dsrc.InsertCommandType = SqlDataSourceCommandType.StoredProcedureDim parms As ParameterCollection = dsrc.InsertParametersDim newid As IntegerAddParameter(parms, "ArtistID", TypeCode.Int32, ParameterDirection.Input, 0, album.ArtistID)AddParameter(parms, "Title", TypeCode.String, ParameterDirection.Input, 0, album.Title)Dim p As New Parameter("NewID", TypeCode.Int32)p.Direction = ParameterDirection.Outputparms.Add(p)Try   Dim rv As Integer = dsrc.Insert()   newid = parms("NewID")   Return newidCatch ex As Exception   Return -1End Try
The row is inserted into the database, but however I try to define and add the NewID parameter it never has a value.
Has anyone tried to do this and can tell me what I am doing wrong?
Jon

Programmatically Setting UpdateParameters For A SQLDataSource Control

Sep 8, 2006

I need to provide defaults and sometimes overrides for items in SQLDataSource's UpdateParameters. I am attempting to do this in a FormView's ItemUpdating and ItemInserting events as follows: //========================================================================
// FormView1_ItemUpdating:
//========================================================================
protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs e) {
// not sure if this is the bets place to put this or not?
dsDataSource.UpdateParameters["UpdatedTS"].DefaultValue = DateTime.Now.ToString();
dsDataSource.UpdateParameters["UpdatedUserID"].DefaultValue = ((csi.UserInfo)Session["UserInfo"]).QuotaUserID;
}
 In the example above I am attempting to set new values for the parameters which will replace the existing values. I have found that using the DefaultValue property works ONLY if there is no current value for the parameter.  Otherwise the values I specify are ingnored.The parameters of an ObjectDataSource provide a Value property but SQLDataSource parameters do not.How can I provide an override value without needing to place the value in the visible bound form element???If you can answer this you will be the FIRST person ever to answer one of my questions here!!!Thanks,Tony

How Do I Programmatically Inert Data Using A SqlDataSource Control?

May 19, 2007

I just want to insert a record into a table using a SqlDataSource control.  But I'm having a hard time finding examples that don't use data bound controlsI have this so far (I deleted the parts not related to the insert):<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:UserPolls %>"    InsertCommand="INSERT INTO [PollAnswers] ([PollId], [AnswerText], [AnswerCount]) VALUES (@PollId, @AnswerText, @AnswerCount)"    <InsertParameters>        <asp:Parameter Name="PollId" Type="Int32" />        <asp:Parameter Name="AnswerText" Type="String" />        <asp:Parameter Name="AnswerCount" Type="Int32" />    </InsertParameters> </asp:SqlDataSource> This is the data source for a gridview control I have on the page.  I could set up an SqlDataSource for this alone if I need to, but i don't know if it would help.  From what I could find, in the code behind I should haveSqlDataSource2.Insert()and SqlDataSource2  will grab the parameters and insert the record.  The problem is I need to set the Pollid (from a session variable) and AnswerText (from a text box) at run time.  Can I do this?Diane

Programmatically Accessing An SQLDataSource With A SELECT COUNT(*) Query.

Jun 20, 2007

I've found example code of accessing an SQLDataSource and even have it working in my own code - an example would be  Dim datastuff As DataView = CType(srcSoftwareSelected.Select(DataSourceSelectArguments.Empty), DataView)  Dim row As DataRow = datastuff.Table.Rows(0)   Dim installtype As Integer = row("InstallMethod")  Dim install As String = row("Install").ToString  Dim notes As String = row("Notes").ToString The above only works on a single row, of course. If I needed more, I know I can loop it.The query in srcSoftwareSelected is something like "SELECT InstallMethod, Install, Notes FROM Software"My problem lies in trying to access the data in a simliar way when I'm using a SELECT COUNT query. Dim datastuff As DataView = CType(srcSoftwareUsage.Select(DataSourceSelectArguments.Empty), DataView) Dim row As DataRow = datastuff.Table.Rows(0) Dim count As Integer = row("rowcnt") The query here is "SELECT COUNT(*) as rowcnt FROM Software"The variable count is 1 every time I query this, no matter what the actual count is. I know I've got to be accessing the incorrect data member in the 2nd query because a gridview tied to srcSoftwareUsage (the SQLDataSource) always displays the correct value. Where am I going wrong here?

SqlDataSource - Need To Refresh Grid When Data Updated Programmatically

Nov 27, 2007

I am sending a GUID to a form via the query string.  If it exists I use helper functions to load most of the form text boxes.  However, if it does not then a blank form is presented and the GUID is stored in a hidden field. 
Regardless, I use this hidden field to populate a grid that is attached to a sqldatasource.
If I then add new datarows to the backend database programmatically, I cannot 'requery' the datasource to include those row upon a postback.  I cannot seem to find a simple way to force the sqldatasource to rerun the query.
Can anyone help.

Using SQLDataSource OnSelecting Event

Jul 21, 2006

I have two SQLDataSource controls on my page that are dynamically fed an SQL SELECT statement. I was thinking that the best way to do this was to give it the select statement that it needs inside the OnSelecting event. Here is the revelent code.

&lt;asp:SqlDataSource OnSelecting=&quot;GetData_Selecting&quot; ID=&quot;DS1&quot; ConnectionString=&quot;&lt;%$ ConnectionStrings:MyConnectionString %&gt;&quot; ProviderName=&quot;&lt;%$ ConnectionStrings:MyConnectionString.ProviderName %&gt;&quot; runat=&quot;server&quot; SelectCommand=&quot;&quot; /&gt;
&lt;asp:SqlDataSource OnSelecting=&quot;GetData_Selecting&quot; ID=&quot;DS2&quot; ConnectionString=&quot;&lt;%$ ConnectionStrings:MyConnectionString %&gt;&quot; ProviderName=&quot;&lt;%$ ConnectionStrings:MyConnectionString.ProviderName %&gt;&quot; runat=&quot;server&quot; SelectCommand=&quot;&quot; /&gt;



protected void GetData_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
System.Diagnostics.Debug.WriteLine(&quot;Getting Data...&quot;);

switch ((sender as SqlDataSource).ID)
{
case &quot;DS1&quot;:
if (Checkbox1.Checked)
{
e.Command.CommandText = &quot;SELECT * FROM table1 WHERE &quot; + BuildQuery(getMylarColumns(), SearchBox.Text);
DS1Panel.Visible = true;
}
break;

case &quot;DS2&quot;:
if (Checkbox2.Checked)
{
e.Command.CommandText = &quot;SELECT * FROM table2 WHERE &quot; + BuildQuery(getFlatFileColumns(), SearchBox.Text);
DS2Panel.Visible = true;
}
break;
}


The problem with this is that the GetData_Selecting method is never executed and thus when I try to execute the query the page PostBacks and nothing happens. Putting equivalent code in the Page_Load method works fine, however I believe having the code execute on each PostBack is the reason I'm having another problem sorting the data in the DataGrids these controls are bound to.

Why is the function never being executed? Is this the ideal way to handle the inclusion of the query in the SQLDataSource?

Using The OnSelected Event Of SqlDataSource

May 18, 2008

Hello,
on my site I have a sqldataSource and a listview working together. But now after selecting data from my database and before binding data to the listview i want to change the data. For example: I select an image filename and i want to check if the file exists, and if it not exists i want to change this filename. How can I do that. My Idea was to use the OnSelected Event of the datasource, but i don't know how to acces the selected data ...
 I hope someone can help me

SqlDataSource Inserting Event Error

Apr 12, 2007

Greetings,
When using Inserting event of SqlDataSource ASP.NET gives me an error when I reference InsertParameter by Name
An SqlParameter with ParameterName 'CreatedByEmployeeId' is not contained by this SqlParameterCollection.
However, when I reference parameter by index everything works.
Is this a bug or I'm doing something wrong?
Here's the code:
<asp:SqlDataSource ID="dsRole" runat="server" ConnectionString="<%$ ConnectionStrings:SecurityConnectionString %>" DeleteCommand="spDeleteRole" InsertCommand="spAddRole" SelectCommand="spGetRole" UpdateCommand="spUpdateRole" DeleteCommandType="StoredProcedure" InsertCommandType="StoredProcedure" SelectCommandType="StoredProcedure" UpdateCommandType="StoredProcedure">
<DeleteParameters>
<asp:Parameter Name="RoleId" Type="Int32" />
</DeleteParameters>
<UpdateParameters>
<asp:Parameter Name="RoleId" Type="Int32" />
<asp:Parameter Name="RoleName" Type="String" />
<asp:Parameter Name="RoleDescription" Type="String" />
<asp:Parameter Name="UpdatedByEmployeeId" Type="Int32" />
</UpdateParameters>
<InsertParameters>
<asp:Parameter Name="RoleName" Type="String" />
<asp:Parameter Name="RoleDescription" Type="String" />
<asp:Parameter Name="CreatedByEmployeeId" Type="Int32" />
</InsertParameters>
<SelectParameters>
<asp:ControlParameter ControlID="GridView1" Name="RoleId" PropertyName="SelectedValue" />
</SelectParameters>
</asp:SqlDataSource>
When using parameter name, I get an error:
Protected Sub dsRole_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles dsRole.Inserting
e.Command.Parameters("CreatedByEmployeeId").Value = Internal.Security.GetEmployeeIdFromCookie(Page.Request.Cookies)
End Sub
When using index instead of name, there's no problem:
Protected Sub dsRole_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles dsRole.Inserting
e.Command.Parameters(2).Value = Internal.Security.GetEmployeeIdFromCookie(Page.Request.Cookies)
End Sub

Should SqlDataSource Selected Event Always Fire?

May 2, 2007

Hi
 In the page load of my webpage I call a databind for a gridview.
It generally calls this event handler :
protected void SqlDataSource1_Selected(object sender, SqlDataSourceStatusEventArgs e)
 
However sometimes (seemingly randomly) it doesn't.
Any ideas?
Thanks

 
protected void Page_Load(object sender, EventArgs e)
{
...
if (searchText != "")
    SqlDataSource1.SelectParameters["search"].DefaultValue = searchText;
else{
SqlDataSource1.SelectParameters["search"].DefaultValue = "";
GridView1.DataBind();

Sqldatasource Onselected Event Not Firing

Oct 3, 2007

Hi All - I've got a simple gridview/sqldatasource page, but the sqldatasource_onSelected event isn't firing.
heres the parameters <SelectParameters>
<asp:QueryStringParameter Name="LicenceID" QueryStringField="LicenceID" Type="string" />
<asp:QueryStringParameter Name="SiteID" QueryStringField="SamplingSiteID" Type="string" />
</SelectParameters>

either or both parameters may be null (ie. not in querystring )  .
If only one of the selectparameters is null, and I remove it, the event fires!!!
The parameters in the stored proc are optional(ie. default = NULL) and it works fine if I test it in SQL .
Whats going on? If there's some error happening, why no error raised? if there are no records returned, the onselected event should still fire shouldn't it?

SqlDataSource OnSelected Event Not Firing

Nov 20, 2007

Hi,
 I have a SqlDataSource whose select statement uses parameters from the selected row on a gridview on the page. So when a row is selected in the gridview, I want the SqlDataSource to do a select using the new parameters, and then I want to inspect the number of rows returned. If 0, I want to set a FormView to insert mode, if >0 I want to set the FormView to edit mode.
The "SqlDataSource2_Selected" sub never fires, so I cannot retrieve the number of rows returned. How can I deal with this? I would like the SqlDataSource to execute a Select each time the Gridview selected row changes. What could prevent "OnSelected" from firing?
 I do have "OnSelected="SqlDataSource2_Selected" within the SqlDataSource tag.
 Thanks in advance for any help with this.

SqlDataSource Inserted Event Appears To Execute Twice!

Nov 9, 2007

Hello
I have a piece of VB.NET code that generates an email on the SqlDataSource Inserted event.  It appears to be executing twice because it is sending two emails.  If I place the code on any other event, it just sends the one email.  Does any have a suggestion on how to handle this?
Protected Sub SqlDataSource1_Inserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles SqlDataSource1.Inserted 
Dim MailServerName As String = "alvexch01"Dim Message As MailMessage = New MailMessage
Message.From = New MailAddress("sender@email.com")Message.To.Add("receiver@email.com")
Message.Subject = "Near Miss"
Message.Body = "Test"
Message.IsBodyHtml = True
Message.Priority = MailPriority.NormalDim MailClient As SmtpClient = New SmtpClient
MailClient.Host = MailServerName
MailClient.Send(Message)
Message.IsBodyHtml = True
Message.Dispose()
End Sub

Deleted Event On Sqldatasource And Output Parameters... Always NULL!!

Apr 18, 2007

I have an event:
Private Sub SqlDataSourceIncome_Deleted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles SqlDataSourceIncome.Deleted
Dim command As SqlClient.SqlCommand
command = e.Command
If command.Parameters("@nReturnCode").Value <> 0 Then
    DROPDEAD()
End If
That  fires from:
<DeleteParameters>
<asp:Parameter Name="nDeletebyId" Type="Int64" />
<asp:Parameter Name="nOtherId" Type="Int64" />
<asp:Parameter Direction="Output" Name="nReturnCode" Type="Int64" />
<asp:Parameter Direction="Output" Name="nReturnId" Type="Int64" />
</DeleteParameters>
End Sub
 
When I:
GridViewIncome.DeleteRow(GridViewIncome.SelectedRow.RowIndex)
But nReturnCode is ALWAYS NULL... I even did a stored procedure that just:
ALTER PROCEDURE [dbo].[sp_nDeletebyId]
 @nReturnCode bigint output,
@nReturnId bigint output AS
SET @nReturnCode = 0
SET @nReturnId = 0
And STILL got nothing but the NULLS... the insert & update stuff works fine, with identical code... it's just the DELETED event that I can't seem to knock.  Has anyone seen this before?  The above sample stored proc did return 0 when executed one the server...
and, BTW, the row is deleted!

i want to execute a finctionX() based on the returned resultset of SQLDataSource. For example, if the SELECT command returns nothing based on a specific search criteria then I want to execute functionX(). Currently, I have a string that displays "No Result" in the GridView in such case.
How to catch the  resultset of SQLDataSource?

ForEach Loop Execution Order

May 27, 2008

Hi

I am designing a ETL system to extract data from multiple systems. I have designed a batch control application and database to manage the process. I was thinking of extending this to include the execution of the SSIS packages. I would basically store all of the package details in the database, and when I am executing a particular systems load, I would get the list of packages required and loop through them in a ForEach loop. The question I have is can I guarantee the order of execution? I will put an order or execution in the DB and when I select the data, I can order by these columns.
I am concerned that in putting the data into a record set in SSIS its order could be changed resulting in the packages executing incorrectly.

Has anyone done anything similar to this and and run into problems, or is it not an issue?
Many Thanks
Michael
