The proposed in my previous response approach is just a simple one and you might need to continue improve it in order to make everything work as expected.
So, in order your changes in the selection get notified to the collection itself you could use behavior instead of an attached property. Inside it you need to attach to the CollectionChanged
event of the collection you are bound to and to the SelectionChanged
event of the ComboBox
. When selection is made the SelectionChanged
event will be fired and you could update the collection you are bound to with the new item that is selected from RadComboBox
Please, check the attached sample that demonstrates that approach.
We hope this will help you.
