This event is raised when the user attempts to end the edit mode on ActiveCell after entering an invalid value. The default behavior is to display an error message and not end the edit mode on the cell. You can change this default behavior by setting the FieldSettings.InvalidValueBehavior property on FieldSettings or by hooking into this event and setting various properties on the associated event args to control the behavior, including what to display in the error message.
Note: To end edit mode you can call the ActiveCell's Cell.EndEditMode method, change the ActiveCell, change the ActiveRecord or call ExecuteCommand(RoutedCommand) with either the DataPresenterCommands' DataPresenterCommands.EndEditModeAndAcceptChanges or DataPresenterCommands.EndEditModeAndDiscardChanges commands.
