I have a RadDataForm, and need to be informed when the form's validation status changes.
What I thought I could do was to listen to RadDataForm.ValidationSummary.Errors.CollectionChanged, but unfortunately, even as late as RadDataForm.Loaded, RadDataForm.ValidationSummary is null.
Is there some event that RadDataForm fires when its validation status changes?
Or some event that RadDataForm fires after its ValidationSummary has been created?
