'Declare a dictionary on the class level:
Private rowIndexer As New Dictionary(Of String, Integer)()


'Then, once the RowDataBind event fires for the first time make the indexer:'
If e.Row.RowType = DataControlRowType.Header Then
	rowIndexer = New Dictionary(Of String, Integer)()
	Dim i As Integer = 0
	While i < e.Row.Cells.Count

'That’s it! Now, all you need to do for example to hide row is to call the following line on the RowDataBind event:
e.Row.Cells(rowIndexer("ndtID")).Visible = False
