I have this code in the itemdatabound event..
If e.Item.Cells(8).Text = "2" Then
Dim t As TextBox =
DirectCast(e.Item.FindControl("txtPendingEd"), TextBox)
If Not t Is Nothing Then
t.Visible = False
End If
End If
e.Item.Cells(1).ToolTip = e.Item.Cells(7).Text
I have debugged and there are rows in the grid with cell(8) text of "2" yet
the TextBox declared above is always "nothing".
Does anyone have any code that they can test this in. I really cannot get
what seems like a simple thing to work.
