This example evaluates the expression and returns the object.

FarPoint.CalcEngine.Expression ex;
FarPoint.Win.Spread.Model.DefaultSheetDataModel dataModel = new FarPoint.Win.Spread.Model.DefaultSheetDataModel(10, 10);
dataModel.AddCustomName("TWICESUM", new FarPoint.CalcEngine.DoubleExpression(10));
dataModel.SetFormula(1, 1, "TWICESUM");
fpSpread1.ActiveSheet.Models.Data = dataModel;
ex = dataModel.GetExpression(1, 1);
dataModel.EvaluateExpression(1, 1, ex);
MessageBox.Show("The expression is " + ex.ToString());

Visual Basic

Dim ex As FarPoint.CalcEngine.Expression

dataModel.SetFormula(1, 1, "TWICESUM")
FpSpread1.ActiveSheet.Models.Data = dataModel
ex = dataModel.GetExpression(1, 1)
dataModel.EvaluateExpression(1, 1, ex)
MessageBox.Show("The expression is " & ex.ToString())
