Theoretically, having a two-way SelectedItem
binding should correctly synchronize the selection in RadDataBoundListBox.
However, there might be something specific to your particular scenario which breaks this behavior. Could you please give us some further details like:
1. Does the new selection update occur after you resume the application from thombstoned state?
2. Is the selection correctly updated when the application is in running state and the View Model binding source updates?
It will also be very helpful if you manage to isolate the issue in a separate project and send it to us for further investigation. You will have to open a new support ticket to do that.
Thanks for your time.
All the best,
the Telerik team
