In a user control, there is a RadComboBox as CellTemplate of GridViewDataColumn. This RadComboBox has binding in ItemsSource and SelectedItem properties and it has SelectionChanged event setted too. In this event I change a object property (my app domain object). When I choose a different value in the combo, all works fine. But, when I close the screen and open again, the event is fired again, with the first value of ItemsSource, and my object property is setted again with original value.
What can I do to solve this issue??
