private void Window_Loaded(object sender, RoutedEventArgs e)
        {
        GrapeCity.Windows.SpreadSheet.Data.CellRange cellr = new GrapeCity.Windows.SpreadSheet.Data.CellRange(0, 0, 3, 3);
        GrapeCity.Windows.SpreadSheet.Data.CellRange cellr2 = new GrapeCity.Windows.SpreadSheet.Data.CellRange(4, 0, 2, 2);
        gcSpreadSheet1.Sheets[0].SelectionPolicy = GrapeCity.Windows.SpreadSheet.Data.SelectionPolicy.MultiRange;
        //gcSpreadSheet1.Sheets[0].SetSelection(0, 0, 3, 3);
        gcSpreadSheet1.Sheets[0].SetSelection(cellr);
        //gcSpreadSheet1.Sheets[0].AddSelection(4, 0, 2, 2);

        gcSpreadSheet1.Sheets[0].AddSelection(cellr2, true);
        //gcSpreadSheet1.Sheets[0].AddSelection(4, 0, 2, 2, true);
        //Specifies the extent (or farthest cell) in the selection of cells.
        gcSpreadSheet1.Sheets[0].ExtendSelection(6, 3);
       gcSpreadSheet1.Invalidate();                       
        }
