private void Page_Load(object sender, System.EventArgs e)
{
   if (this.IsPostBack) return;

 FpSpread1.ActiveSheetView.ColumnCount = 8;
 FpSpread1.ActiveSheetView.RowCount = 10;
 FpSpread1.ActiveSheetView.SelectionBackColor = Color.Yellow;
 FarPoint.Web.Spread.Model.ISheetSelectionModel model = FpSpread1.ActiveSheetView.SelectionModel;
 
 bool b1, b2, b3;
 int i1;
 model.AddSelection(0, 0, 3, 3);
 b1 = model.IsAnyCellInColumnSelected(2);
 b2 = model.IsAnyCellInRowSelected(2);
 b3 = model.IsSelected(1,1);
 i1 = model.Count;
 ListBox1.Items.Add(Convert.ToString(b1));
 ListBox1.Items.Add(Convert.ToString(b2));
 ListBox1.Items.Add(Convert.ToString(b3));
 ListBox1.Items.Add(Convert.ToString(i1));
}

private void Button1_Click(object sender, System.EventArgs e)
{
 FarPoint.Web.Spread.Model.ISheetSelectionModel model = FpSpread1.Sheets[0].SelectionModel;
 model.RemoveSelection(0, 0, 3, 3);
}
