Question

Repeater ItemCommand

Asked by: BobCSD

I'm using a repeater to list rows in a table. I have a button for each row. On click, I want to know the ID of the row.

I can store the ID in a hidden field, but is there a better way?
Also, I want to know another value that I don't wish to display, should I use a hidden field?

Then on the ItemCommand, what do I do to know the button has been clicked and if so, retrieve the values in those hidden fields, or ID's via other means you suggest?

Please provide the code in VB if possible, or C# if you can't. I can convert. But don't direct me to a page unless it specifically answers this question, as I've been looking all morning for something like this, and I do get tired of those who google stuff like "ItemCommand" and post a link and hope to get points for doing what I've already done and not bothering to answer the question.

thanks!

<asp:Repeater ID="repGuide" runat="server">
            <ItemTemplate>
                <tr>
                    <td class="ReportCellText ReportTableBorder">
                        <asp:HiddenField ID="hfQuestionAnswerId" runat="server" />
                        <asp:HiddenField ID="hfQuestionValueId" runat="server" />
                        <asp:Label ID="lblQuestion" runat="server"></asp:Label>
                        <asp:Button ID="btnEdit" runat="server" Text="Edit" />
                    </td>
                </tr>
            </ItemTemplate>
        </asp:Repeater>
 
 
    Protected Sub repGuide_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.RepeaterCommandEventArgs) Handles repGuide.ItemCommand
 
 
???
 
    End Sub

set CommandName="cmdEdit" for you button in the markup ..
then the item command should look something like below:

Protected Sub Repeater1_ItemCommand(ByVal source As Object, ByVal e As RepeaterCommandEventArgs)
    If e.CommandName = "cmdEdit" Then
        Dim btn As Button = DirectCast(e.CommandSource, Button)
        If btn IsNot Nothing Then
            Dim hf1 As HiddenField = DirectCast(btn.NamingContainer.FindControl("HiddenField1"), HiddenField)
            If hf1 IsNot Nothing Then
                Dim value As String = hf1.Value
            End If
        End If
    End If
End Sub

Instead of HiddenField other way would be multiple arguments in CommandArgument
