I am facing issue with Chat Control. When I tried to change datasource of control, Messages in Chat UI does not reflect.
I have List of User in listbox. Each User has Observable collection of TextMessages. When User selection changed, I bind datasource to selected user messages. I assume that Chat control will update its UI by selected User messaged. But it is not working.
I tried to clear MessageListItems on selection change, and re-bind data source to selected user's messages. In this case Chat UI does not show any messages.
For reference I have uploaded my sample project on Google drive.
