Example
This example evaluates the specified expression.
FarPoint.Web.Spread.Model.DefaultSheetDataModel dm;
dm = FpSpread1.ActiveSheetView.DataModel;
FarPoint.CalcEngine.Expression ex;
object o; 
FpSpread1.ActiveSheetView.Cells[0, 0].Value = 10; 
FpSpread1.ActiveSheetView.Cells[1, 0].Value = 10; 
FpSpread1.ActiveSheetView.Cells[2, 0].Formula = "A1 + A2"; 
ex = dm.ParseFormula(2, 0, "A1+A2"); 
o = dm.EvaluateExpression(2, 0, ex); Response.Write(o.ToString()); 
Dim dm As FarPoint.Web.Spread.Model.DefaultSheetDataModel
dm = FpSpread1.ActiveSheetView.DataModel
Dim ex As FarPoint.CalcEngine.Expression
Dim o As Object
FpSpread1.ActiveSheetView.Cells(0, 0).Value = 10 
FpSpread1.ActiveSheetView.Cells(1, 0).Value = 10 
FpSpread1.ActiveSheetView.Cells(2, 0).Formula = "A1 + A2" 
ex = dm.ParseFormula(2, 0, "A1+A2")
