webform datagrid 2 select button columns

[mapfax]

I have 2 select button columns in my webform datagrid with each button's property set to the 'select' command name. How can I determine the column index selected for each of the buttons so that I then can run different code in the 'datagrid_selec tedindexchanged ' event procedure?

OK I think I've solved this using ItemCommand CommandSource of the datagrid:

 Private Sub masterDataGrid_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles masterDataGrid.ItemCommand
      
        If CType(e.CommandSource, LinkButton).Text.ToString = "Select Hdr" Then
            Session("ColumnIndex") = 0
        ElseIf CType(e.CommandSource, LinkButton).Text.ToString = "Select Sub" Then
            Session("ColumnIndex") = 1
        End If

    End Sub
