Edit form in radgrid control does not retain value when server-side validation failed

[My Nguyen The]

I have a radgrid control bind to an object datasource. In the business layer, I have some validation check to make sure input data is valid and if it not the business layer wil throw an exception.

In the ItemUpdated event of the radgrid, I have write some logic to catch the exception from the business layer:

            If e.Exception IsNot Nothing Then
                e.ExceptionHandled = True
                e.KeepInEditMode = True

                Response.Write(e.Exception.Message)
            End If

Everything works fine except that the edit form of radgrid control does not retain the new value when server-side validation failed.

I was trying to apply that logic to a form view / detail view and everything works as expected, when server-side validation failed, the new values are remain and the user can modify the invalid one and perform update action again.

Am I missing some thing with the radgrid control ?
Any help would be appreciated.
