How to validate an Expression

[Tharindu Pati]

Hi,

I am tring to add a column with a expression dynmaically to gridgroupingcontrol.
Since its dynamic user is spesifing the expression dynamincally. So it could be invalid expression. When this happen no expception is thrown but data and the gridgroupingcontrol become unresponsive.

Is there away to check the validiy of the expression before bunding it to the controls.

Thanks

If you have a string you want to test as being a valid expression, you can use the grid.TableDescriptor.ExpressionFieldEvaluator.IsExpressionValid method to do so.
