How to Set TabIndex=-1 for Expand Collapse Column on Server Side?

[Rob]

The title says it all.  I have a hierarchial grid and for tabbing reasons, I only want textboxes to get focus.  I've set the TabIndex to -1 for all my my gridbuttoncolumns and gridclientselectcolumns in the prerender() event.  Expand/Collapse column is the only column left that I need to deal with like this.

Thanks.

Is this even possible?  I could really use some help.

After delving deep into the help file, I came up with this working solution:

    Protected Sub dg_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles dg.ItemCreated
        If TypeOf e.Item Is GridDataItem Then
            Dim gridItem As GridDataItem = CType(e.Item, GridDataItem)
            Dim cell As TableCell = gridItem("ExpandColumn")
            CType(cell.Controls(0), Button).TabIndex = -1
        End If
    End Sub
