Hi,

I have a page with a grid and a commanditemtemplate with link buttons. I am trying to access the buttons in the command item template on the page pre-render event. Based on the samples I have found I added the following code to the pre-render event, but I keep getting the IndexOutOfRange exception error on the first line.

Private Sub WBC_SEC_Security_Users_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender

Dim cmditem As GridCommandItem = DirectCast(rgvSecurityUsers.MasterTableView.GetItems(GridItemType.CommandItem)(0), GridCommandItem)

Dim lnkAdd As LinkButton = TryCast(cmditem.FindControl("lbtAdd"), LinkButton)

End Sub

Reading through the forums the problem seems to be caused by having the CommandItemDisplay property set to none but I have mine set to Top. The only thing that is different on my page is that it is has a master page.

Does anyone know what could be causing this problem.

Thank you for your help.
Tracy
