Example
This example evaluates the specified expression.
FarPoint.Web.Spread.Model.IExpressionSupport2 es;
es = 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 = es.ParseFormula(2, 0, "A1+A2"); 
o = es.EvaluateExpression(2, 0, ex); 
Response.Write(o.ToString()); 
Dim es As FarPoint.Web.Spread.Model.IExpressionSupport2
es = FpSpread1.ActiveSheetView.DataModel
Dim ex As FarPoint.CalcEngine.Expression
Dim o As Object
