'Declaration
 
Function EvaluateExpression( _
   ByVal row As Integer, _
   ByVal column As Integer, _
   ByVal expression As Expression _
) As Object

'Usage
 
Dim instance As IExpressionSupport2
Dim row As Integer
Dim column As Integer
Dim expression As Expression
Dim value As Object
 
value = instance.EvaluateExpression(row, column, expression)

object EvaluateExpression( 
   int row,
   int column,
   Expression expression
)

Object containing the results of the evaluation

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());

Visual Basic

Dim es As FarPoint.Web.Spread.Model.IExpressionSupport2
es = 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 = es.ParseFormula(2, 0, "A1+A2") 
o = es.EvaluateExpression(2, 0, ex)
Response.Write(o.ToString())
