    What would be the best way to tell the DataboundListbox of the selected item upon restore from tombstone or (app restart from a kill)?  Assuming you had selected something in the listbox, previously.   Even though i set the SelectedItem property to TwoWay mode it doesn't reselect the appropriate item in the list box.  Any suggestions?  I have tried getting the value in the container and looking for it but this doesn't appear to get my anything remotely close.

    Hi Morgan,

    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,
