ExpressionFieldEvaluator::IsExpressionValid() - usage?

I''m trying to use the IsExpressionValid() method on the ExpressionFieldEvaluator class to determine if an expression string is valid. But this method returns false for every string I validate - even strings that I think are correct. I modified the "Syncfusion\Essential Studio\4.1.0.10\Windows\Grid.Grouping.Windows\Samples\GridGroupingTutorial\Project3" sample to use the ExpressionFieldEvaluator as follows: ExpressionFieldEvaluator expEvaluator = new ExpressionFieldEvaluator(this.gridGroupingControl1.TableDescriptor); string errorStr; bool validExpression = expEvaluator.IsExpressionValid(this.expDesc.Name, this.expDesc.Expression, out errorStr); NOTE: I put this code in the constructor after InitializeComponent(). this.expDesc is the "PercentWins" expression field - I simply made a variable for it so I can get access to it. Is there something wrong with the way I''m using the ExpressionFieldEvaluator, or is this a bug? thanks, Heath

Hi Heath, This is a bug and it is fixed, in the next versions of 4.1 that will be resolved. Best regards, Stanley
