if (dlg == DialogResult.Yes)
{
     cs = (FarPoint.Win.Spread.Model.ICalculationSupport)fpSpread1.ActiveSheet.Models.Data;
     cs.AutoCalculation = true;
     fpSpread1.ActiveSheet.SetValue(0, 1, 50);
}
else if(dlg == DialogResult.No)
{
     cs = (FarPoint.Win.Spread.Model.ICalculationSupport)fpSpread1.ActiveSheet.Models.Data;
     cs.AutoCalculation = false;
     fpSpread1.ActiveSheet.SetValue(0, 1, 50);
}
