[Solved] RadGrid Batch Update - Disable Textbox in a TemplateColumn

[Neelima]

I'm working on the RadGrid batch update like the one shown in one of the demos. I need to disable textbox in a template column of the RadGrid based on the condition.

If the column was a BoundColumn I would use the following code in the Grid's PreRender event. But how to handle this with the batch update Grid and a TemplateColumn.

Private Sub RadGrid1_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid1.PreRender
     Dim status As String = Request.QueryString(0)
     If status = "Future" Then
         For Each column As GridColumn In RadGrid1.Columns
             If (column.UniqueName = "Start_Dt") Then
                 CType(column, GridBoundColumn).ReadOnly = False
                 CType(column, GridBoundColumn).DataFormatString = "{0:D}"
                 Exit For
             End If
         Next
     Else
         For Each column As GridColumn In RadGrid1.Columns
             If (column.UniqueName = "BoundDate") Then
                 CType(column, GridBoundColumn).ReadOnly = True
                 CType(column, GridBoundColumn).DataFormatString = "{0:D}"
                 Exit For
             End If
         Next
     End If
 End Sub

Thank you!!
