Hi there,
I've seen a couple of forum posts asking this question but do not see any actual resolutions. When binding to a collection of objects that implement the INotifyDataErrorInfo interface, we do see proper invalid row notifications and the correct tooltip for the validation error message. However, no matter what combination of properties I set on the grid, the columns, or the bindings themselves, I can never seem to get a ValidationSummary to display the same messages. We do not see a problem when validating a form with controls like the RadComboBox. We do our validation all at once on the objects themselves and manually raise the errors that are found. Is there a proper combination of settings to have to support this scenario? It simply looks like the RadGridView is eating up the errors and not sending them out to the container.
Thanks!
