I am using the XamDataGrid with built-in validation feature. The problem I am having is that even when there are no errors in the object the validation error icon from the row does not disappear.

For instance, when a new row is added it will have validation errors but as the fields are filled in then the error icons from the cells start to disappear. However, even when all the icons from each cell have disappeared the icon on the row itself doesn't.

One way I have found to fix this is to call PropertyChanged event with empty string as property name. I do this at the same time I raise the PropertyChanged event for Error property on the business object. However, the problem with this is that it makes a normal data entry form (for the same business object) very slow because when user types something in a form and presses tab, it would raise notification event for all the properties.

Any help would be appreciated. Thanks.
