Hi,

I have put an entity level data annotation for validation 

[

CustomValidation(typeof(TestValidators), "PreventExpensiveUnits")]

public partial class TestMessage

and cannot make it to show validation error in ValidationSummary or in xamGrid itself. When I do this for property level validation, everything works fine - cell is getting red rectangle and error and ValidationSummary shows the error for this cell.

Does anydoby have any idea how to make entity level validation working?

Thanks.
