Like if it sort ascending a msgbox would prompt out saying you sort ascending. I would like to know which datagridevent it is. If possible any tips of how to tell whether the column is sorted or not? i found this link but its actually Web Form i need to do it in windows form any ideas?

  If _Data_Table.Rows.Count > 0 Then
        datagridview.DataSource = _Data_Table


        datagridview.Sort(grd_Cadastro.Columns("Your column name"), System.ComponentModel.ListSortDirection.Descending)


        datagridview.AutoResizeColumns()
        datagridview.ClearSelection()



    Else
        datagridview.DataSource = Nothing
    End If
