Hi Sue,
The Type should be the same as control's type <asp:Table
ID="CaseNumberH eaderTable" Runat="Server" />. Otherwise, there will be an
error. If FindControl menthod returns nothing, there will also be an error.
You can use code similar to the following to perform the cast.
Private Sub DataGrid1_ItemD ataBound(ByVal sender As System.Object, ByVal e
As System.Web.UI.W ebControls.Data GridItemEventAr gs) Handles
DataGrid1.ItemD ataBound
If e.Item.ItemType = ListItemType.He ader Then
Dim ctrl As Control =
e.Item.FindCont rol("CaseNumber HeaderTable")
If Not ctrl Is Nothing Then
CaseNumberHeade rTable = CType(ctrl, Table)
setCaseNumberHe aderTable()
End If
End If
End Sub
Please let know if it helps. Thanks.
Lewis

| This is exactly what I wish to do. I have tried the code
| below (modified for my object names) and got an invalid
| cast error message at the CType line. I know this is
| simple, I'm just not tripping onto the correct syntax
| <sigh>. I've tried various options for the CType without
| success. Any other ideas?
