Apologies if this sounds a silly question, but I'm still learning asp.net. Do you mean change sender.CommandArgument to e.CommandArgument ? The reason I ask is that this produces the error BC30456: 'CommandArgument' is not a member of 'System.EventArgs'.

Thanks,

Sorry I am thinking of an ImageButton not a standard button; What you would actually have to do would be to loop through the datalist control collection, something like this:

        Dim objC As Control
        Dim intI as integer

        For Each objC In dl.Controls
            If TypeOf objC Is Button And objC Is sender Then
                Dim btn As Button = CType(objC, Button)
                intI = btn.CommandArgument
            End If
        Next

This will set intI to the value of the buttons command argument
