Question:

The ComboBox in question is bound to a custom column on the entity. I have the binding descriptors for all of my ComboBoxes set up with DataSourceUpdateMode = OnPropertyChanged so I can instantly detect changes. The ColumnChanged event fires as expected for all of my ComboBoxes except this one. Is there some reason why the event wouldn't fire for a control bound to a custom column?

Answer:

There is no guarantee that changing a custom property will fire an OnPropertyChanged event.  This will happen if the custom property changes a persistable column (e.g., "Age" will fire an event if "Birthdate" also changes).  You can also fire the event yourself.  Use the ForcePropertyChanged() method.
