var valid1 = GrapeCity.Windows.SpreadSheet.Data.DataValidator.CreateNumberValidator(GrapeCity.Windows.SpreadSheet.Data.ComparisonOperator.GreaterThan, "5", "20", true);
GcSpreadSheet1.Sheets[0].Cells[1, 1].DataValidator = valid1;
GcSpreadSheet1.Sheets[0].Cells[1, 0].Text = "A number greater than 5 is valid.";

private void GcSpreadSheet1_ValidationPasting(object sender, GrapeCity.Windows.SpreadSheet.UI.ValidationPastingEventArgs e)
        {
            TextBox1.Text = e.IsInvalid.ToString();
        }

private void GcSpreadSheet1_ValidationDragDropBlock(object sender, GrapeCity.Windows.SpreadSheet.UI.ValidationDragDropBlockEventArgs e)
