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.
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: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ <%@ Page Language="VB" AutoEventWireup="false" CodeFile="Editor.aspx.vb" Inherits="Editor" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Data Verification Editor</title> </head> <body> <form id="form1" runat="server"> <asp:SqlDataSource ID="SQLDS_Fill" runat="server" ConnectionString="<%$ ConnectionStrings:Test %>" SelectCommand="Current_sp" SelectCommandType="StoredProcedure" DataSourceMode="DataSet"> </asp:SqlDataSource> <asp:SqlDataSource ID="SQLDS_Update" runat="server" ConnectionString="<%$ ConnectionStrings:Test %>" SelectCommand="Validation_sp" SelectCommandType="StoredProcedure" DataSourceMode="DataReader" UpdateCommand="UPDATE_sp" UpdateCommandType="StoredProcedure"> <UpdateParameters> <asp:ControlParameter Name="SelectedID" ControlID="Ver_ddl" PropertyName="SelectedValue" Type="Int16" /> </UpdateParameters> </asp:SqlDataSource> <table style="width:320px; background-color:menu; border-right:menu thin ridge; border-top:menu thin ridge; border-left:menu thin ridge; border-bottom:menu thin ridge; left:3px; position:absolute; top:3px;"> <tr> <td colspan="2" style="font-family:Tahoma; font-size:10pt;"> Please select one of the following:<br /> </td> </tr> <tr> <td colspan="2"> <asp:DropDownList ID="Ver_ddl" runat="server" DataSourceID="SQLDS_Update" DataTextField="Title" DataValueField="ID" style="width: 100%; height: 24px; background: gold"> </asp:DropDownList> </td> </tr> <tr> <td style="width:50%;"> <asp:Button ID="Submit_btn" runat="server" Text="Submit" Font-Bold="True" Font-Size="8pt" Width="100%" /> </td> <td style="width:50%;"> <asp:Button ID="Done_btn" runat="server" Text="Done" Font-Bold="True" Font-Size="8pt" Width="100%" /> </td> </tr> <tr> <td colspan="2"> <asp:Label runat="server" ID="Saved_lbl" style="font-family:Tahoma; font-size:10pt;"></asp:Label> </td> </tr> </table> </form> </body> </html> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ And here's my code behind: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Imports System.Data Imports System.Data.SqlClient Partial Class Editor Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load Saved_lbl.Text = "" Done_btn.Attributes.Add("OnClick", "window.location.href='Rpt.htm';return false;") Dim View1 As New DataView Dim args As New DataSourceSelectArguments View1 = SQLDS_Fill.Select(args) Dim Row As DataRow For Each Row In View1.Table.Rows Ver_ddl.SelectedValue = Row("ID") Next Row SQLDS_Fill.Dispose() End Sub Protected Sub Submit_btn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Submit_btn.Click SQLDS_Update.Update() Saved_lbl.Text = "Thank you.

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 %>" SelectCommand="SELECT [User_ID], [User_Name], [FirstName], [LastName], [Company_Name], [Department_Name] FROM [CompanyDepartment] WHERE ([User_Name] = @User_Name)" OnSelected="SqlDataSource2_Selected"> <selectparameters> <asp:sessionparameter DefaultValue="TheirUserName" Name="User_Name" SessionField="TheirUserName" Type="String" /> </selectparameters> </asp:SqlDataSource>
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 <%@ Page Language="C#" %>

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.
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
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)
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.
One of the requirements of the UpdateParameters for a GridView I'm building is that the fields that are being edited via EditItemTemplates are passed back to the UpdateParameter as XML. How would I go about combining the fields from the GridView/EditItems into an XML string that I can set as an asp:Parameter? Thanks.
OK guys, I'm sure I'm doing something stupid here but after 2 days I find myself extremely frusted... Any help would be appreciated I'm tring to write an update procedure for an SqlDataSource control that will allow me to chage the primary key values of a record in the table. Everything seems to work fine with the exception of obtaining the old values (the primary key before its changed by the end user) during the update. I've read several articles on the web an in the forums on this topic. Much of it has to do with the .NET beta version alteration from "original_{0}" to "{0}". I believe those conversations do not describe my problem. Anyhow, onto some source code. Here's the ASP source code for a grid view and sql data source. <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="productName,productURL" DataSourceID="SqlDataSource1" EmptyDataText="There are no data records to display."> <Columns> <asp:CommandField ShowSelectButton="True" /> <asp:BoundField DataField="productName" HeaderText="productName" ReadOnly="True" SortExpression="productName" /> <asp:BoundField DataField="productURL" HeaderText="productURL" ReadOnly="True" SortExpression="productURL" /> <asp:BoundField DataField="productSupportURL" HeaderText="productSupportURL" SortExpression="productSupportURL" /> <asp:BoundField DataField="description" HeaderText="description" SortExpression="description" /> <asp:BoundField DataField="modified" HeaderText="modified" SortExpression="modified" /> <asp:BoundField DataField="userid" HeaderText="userid" SortExpression="userid" /> <asp:BoundField DataField="useridDomain" HeaderText="useridDomain" SortExpression="useridDomain" /> <asp:BoundField DataField="sortOrder" HeaderText="sortOrder" SortExpression="sortOrder" /> </Columns> </asp:GridView> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:SBAAdminConnectionString1 %>" DeleteCommand="DELETE FROM [homePageList] WHERE [productName] = @old_productName AND [productURL] = @old_productURL" InsertCommand="INSERT INTO [homePageList] ([productName], [productURL], [productSupportURL], [description], [modified], [userid], [useridDomain], [sortOrder]) VALUES (@productName, @productURL, @productSupportURL, @description, @modified, @userid, @useridDomain, @sortOrder)" ProviderName="<%$ ConnectionStrings:SBAAdminConnectionString1.ProviderName %>" SelectCommand="SELECT [productName], [productURL], [productSupportURL], [description], [modified], [userid], [useridDomain], [sortOrder] FROM [homePageList]" UpdateCommand="UPDATE homePageList SET productSupportURL = @productSupportURL, description = @description, modified = @modified, userid = @userid, useridDomain = @useridDomain, sortOrder = @sortOrder, productName = @productName, productURL = @productURL WHERE (productName = @original_productName) AND (productURL = @original_productURL)" OldValuesParameterFormatString="original_{0}"> <DeleteParameters> <asp:Parameter Name="old_productName" Type="String" /> <asp:Parameter Name="old_productURL" Type="String" /> </DeleteParameters> <UpdateParameters> <asp:Parameter Name="description" Type="String" /> <asp:Parameter Name="modified" Type="DateTime" /> <asp:Parameter Name="userid" Type="String" /> <asp:Parameter Name="useridDomain" Type="String" /> <asp:Parameter Name="sortOrder" Type="Single" /> <asp:Parameter Name="productName" Type="String" /> <asp:Parameter Name="productURL" Type="String" /> <asp:Parameter Name="productSupportURL" Type="String" /> <asp:ControlParameter ControlID="GridView1" Direction="InputOutput" Name="original_productName" PropertyName="SelectedValue" /> <asp:ControlParameter ControlID="GridView1" Direction="InputOutput" Name="original_productURL" PropertyName="SelectedValue" /> </UpdateParameters> <InsertParameters> <asp:Parameter Name="productName" Type="String" /> <asp:Parameter Name="productURL" Type="String" /> <asp:Parameter Name="productSupportURL" Type="String" /> <asp:Parameter Name="description" Type="String" /> <asp:Parameter Name="modified" Type="DateTime" /> <asp:Parameter Name="userid" Type="String" /> <asp:Parameter Name="useridDomain" Type="String" /> <asp:Parameter Name="sortOrder" Type="Single" /> </InsertParameters> </asp:SqlDataSource>I added a text box for every field in the grid to the form and update the fields when the user selects a record in the GridView. I then added an Update button to the form and tied the event to this procedure: Protected Sub bUpdate_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles bUpdate.Click 'if the user has not entered key fields! If missingKeyFields() Then Exit Sub
End If
Dim count, so As Integer Dim uDomain, uid As String
'parse out the user id and domain. Try If HttpContext.Current.User.Identity.Name = "" Then uid = "unknow" uDomain = "unknown"
'insert the record. count = Me.SqlDataSource1.Update() Me.lCommandInfo.Text = count.ToString + " record was updated."
End Sub The net result of the procedure is the message "0 record was updated." when I select a record in the gridView and then edit the "productName" field and click Update. In an attempt to trace down the problem I added this code: Protected Sub SqlDataSource1_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles SqlDataSource1.Updating
Message.Text = e.Command.CommandText Message.Text += "<br>" For lp As Integer = 0 To e.Command.Parameters.Count - 1 Message.Text += e.Command.Parameters(lp).ParameterName + "=" + e.Command.Parameters(lp).Value Message.Text += "<br>"
Next
End Sub The message label displays the following text:UPDATE homePageList SET productSupportURL = @productSupportURL, description = @description, modified = @modified, userid = @userid, useridDomain = @useridDomain, sortOrder = @sortOrder, productName = @productName, productURL = @productURL WHERE (productName = @original_productName) AND (productURL = @original_productURL) @description=interesting! @modified=3/15/2007 4:07:31 PM @userid=unknow @useridDomain=unknown @sortOrder= @productName=ok22 @productURL=http @productSupportURL=http @original_productName=ok @original_productURL=ok Notice how the "@original_productURL" has the same value as the "@original_productName"? This should not be the case. The @original_productURL should equal "http" since I didn't update the field's value. It seems like the second field of the primary key is not getting updated or passed to the @original_productURL parameter. Since .NET handles the @original_{0} parameters I don't know why the field isn't being properly updated. Any thoughts on how to track down the root cause of my problem... Or better yet any thoughts on a work around to my problem? Thanks,Johnny
I need to know how to setup the ControlParameter for a template control in my Gridview? I have a datepicker in my template and I need to know how to refer to it in the ControlParameter of the SQLDataSource control. <UpdateParameters> <asp:ControlParameter Name="dp_start" ControlID="bdpPlanStart" PropertyName="SelectedValue" Type="Datetime" /> Here is the template:<asp:TemplateField HeaderText="Start" SortExpression="dp_start"> <ItemTemplate> <%#DataBinder.Eval(Container, "DataItem.dp_start", "{0:d}")%> </ItemTemplate> <EditItemTemplate> <BDP:BasicDatePicker id="bdpPlanStart" SelectedValue='<%# DataBinder.Eval(Container.DataItem,"dp_start") %>' runat="server" DateFormat="d"> </BDP:BasicDatePicker> </EditItemTemplate> </asp:TemplateField>
I am trying to reload an AJAX control without reloading the page. This question may belong under AJAX, but I'm not sure if I'm managing the SqlDataSource correctly. I want to set the SelectCommand to a new SQL statement and refresh the form on the screen. My code is below. It doesn't seem to be working. Do I need to call something else or is this correct and the problem is with that nasty AJAX?SqlDataSource oSqlDataSource1 = (SqlDataSource) oContentPlaceHolder1.FindControl("SqlDataSource1");oSqlDataSource1.SelectCommand = "SELECT * FROM WorkHistory WHERE WorkHistoryID = " + sWorkHistoryID;oSqlDataSource1.Select(DataSourceSelectArguments.Empty);

Hi, I have a repeater which i need to build editing capabilities into in a similar way as the GridView, just a little unsure how to tie it together. Ideally i would like to use a GridView as this would do all of the work for me however it looks like I need to go with the repeater due to the nested nature of the data I am working with. What is the best way to go about updating the data source from within a repeater? I have already built the edit interface with some MultiViews in the Repeater control and handling the ItemCommand event, just not sure how to actually update the data source. Can I still use the SqlDataSource wizard to generate all of the SQL for me? If so, within the ItemCommand event handler I have the data i want to update back to the database by using the FindControl method and retrieving the Text, but how do i get this data into the SqlDataSource object and update the database? Are there any samples available which show how to update a datasource using a repeater? Your help is much appreciated trenyboy
I'm referring to this bug, which I've seen a lot of people (including me) run into: http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=93937 Has anyone heard if MS plans to fix this soon? Thanks
Hi,I'm trying to create a registration page that I've divided into multiple pages (first page for basic details, next page for address, etc.). I insert the record in the first page, and update it in the other pages. I pass the newly created ID to the other pages using the Page.PreviousPage property. In the second page, I have the SqlDataSource configured as "SELECT * FROM [Table] WHERE ID = ?", and the UpdateCommand is "UPDATE .... WHERE ID = ?". In Page_Load, I am updating the SelectCommand to "SELECT ... WHERE ID = " & intID, and the UpdateCommand similarly. The I do a dtlsvw.Databind()But when I go to the next page (the newly created ID is being passed properly), the update doesn't do anything. The new record doesn't contain the values in the detailsview. Can somebody help me out? Thanks,Wild Thing
I have a Gridview (edit enabled), connected to a SQLDataSource. SQLDataSource populates the gridview from 1 SelectCommand. figure1: ColumnA | ColumnB | ColumnC
I have 2 SQL Server 2005 tables: Table1 and Table2 Now on my SQLDataSource's UpdateCommand, I want the value of ColumnB to go to Table1's ColumnB, and ColumnC to go to Table2's ColumnC. How do I do this? I understand I can't do this with 1 UPDATE-SET sql query. Maybe I can with stored procs or something, but im kinda noobish when it comes to this. How? Thanks
Hi, I have such a problem:I try to update (or insert) a row in my table and i fail althought i,ve read many posts here. I.ve created a button and "on_click" event to this button and want that event to update or insert a record in my table. I wrote: protected void selectButton_Click(object sender, EventArgs e) { String taskID = projectsGridView.SelectedRow.Cells[0].Text; usersSqlDataSource.UpdateCommand = "update [Users] set [TaskID]=@task where [UserID]=1"; usersSqlDataSource.UpdateParameters.Add("task", taskID); usersSqlDataSource.Update(); } The application creates error in the last line of code (usersSqlDataSource.Update();) and i receive such an error:You have specified that your update command compares all values on SqlDataSource 'usersSqlDataSource', but the dictionary passed in for oldValues is empty. Pass in a valid dictionary for update or change your mode to OverwriteChanges. For me it looks like there is a problem while setting parameters. Shall i change some properties of the sqlDataSource or GridView? Please help..
ello all 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...

I’m trying to create a sqlDataSource using the wizard, I can get the select statement, the here clause and the order by clause but when I click on the Advanced button the options to generate the insert, update and delete statements are not available. Does anyone know what am I doing wrong?
Here is the problem. I have table such as this PK selection VARCHARPK selection_choice VARCHAR show BIT When I use the sqlDataSource to create an update it creates this.UPDATE lu_selection_choices SET show = @show WHERE (selection = @selection) AND (selection_choice = @selection_choice) Now this is OK, but when you perform an update and in say a details control you change the selection_choice the value of the parameter @selection_choice is going to be equal to the old data. So it performs a successful update on show which isn't being changed selection_choice is. So the questions is. Is there anyway to tell the update function of the datasource to insert the a new parameter with the SET selection_choice = @SOME NEW PARAM slection_choice? Thanks, Darren King
Hi - I'm using .net2, and have a gridview, populated by a SQL Datasource (Edit, Insert, Delete, Select). Like we all used to do with the datagrid, I've added text boxes into the footer, and a link button, which I'd like to use to fire the Update command. How do I get the link button to trigger the update command? Thanks, Mark

Hi all: I have a list of items (actually a relation in which a user has selected an item, along with a rating for the item) in an Access database table, connected to my app with a SqlDataSource and bound to a repeater. The repeater displays the items to the user along with a dropdown box to show the rating, and allow the user to update it. The page connects and displays correctly. My problem is that when the user submits the page and I iterate through the repeater items to update each rating, the updates are not being completed in the database. The update works if I hard-code a value for the rating into the query itself, but not when using an updateparameter (pTaskRating below). In other words if I replace pTaskRating with '5', all the correct records will be found and have their ratings updated to 5. That means that the mySurveyId and pTaskId(DefaultValue) parameters have to be working, because the right records are found, but I can't seem to update records based on the DefaultValue of the pTaskRating parameter, even though I can verify that the DefaultValue is correct by placing a watch on it. It seems that my problem must be in my use of that particular parameter in the query, either in properties of the parameter or in the value assigned to it. I am extremely frustrated - any ideas would be greatly, greatly appreciated. Thanks! Bruck The table I'm pulling from and updating looks like this: SURVEY_ID (Text 50), TASK_ID (Long Int), RATING_ID (Long Int) Here's my ASPX for the main data source: <asp:SqlDataSource ID="sqlTaskSelections" runat="server" ConnectionString='Provider=Microsoft.Jet.OLEDB.4.0;Data Source="abc.mdb";Persist Security Info=True;Jet OLEDB:Database Password=xyz' ProviderName="System.Data.OleDb" SelectCommand="SELECT [SURVEY_ID], [TASK_ID], [RATING_ID] FROM [TBL_TASK_SELECTION] WHERE [SURVEY_ID] = mySurveyId" UpdateCommand="UPDATE [TBL_TASK_SELECTION] SET [RATING_ID] = pTaskRating WHERE ([SURVEY_ID] = mySurveyId) AND ([TASK_ID] = pTaskId)"> <UpdateParameters>
<asp:SessionParameter Name="mySurveyId" SessionField="SurveyId" DefaultValue="" /><asp:Parameter Name="pTaskId" DefaultValue="" /><asp:Parameter Name="pTaskRating" DefaultValue="" /> </UpdateParameters> And here's the repeater (the Task ID and Rating are stored in hidden fields for easy access later): <asp:Repeater ID="rptTaskSelections" runat="server">
<FooterTemplate></td></tr></table></FooterTemplate> </asp:Repeater> And here's the page load and submit VB: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
'BIND / LOAD RATINGS TO DROPDOWN BOXES HEREDim i As IntegerDim cbCurrentRating As DropDownListDim hCurrentRating As HiddenFieldrptTaskSelections.DataSource = sqlTaskSelectionsrptTaskSelections.DataBind()
