We're working on a silverlight 4 RC project and we're using a radtabcontrol binded to a datasource. Each radtabitem has a header template and a content template. In the content template we instantiate an our user control. The problem is that for each tab item selection, the existing user control is destroyed and re-created and this behavior triggers a wcf call that we don't want.
In a previous Silverlight 3 project we used the same template and all is working fine (no re-creation of user control in radtabitem content template).
So, could you help us with this strange behavior?
