    I just implemented the slideView control for images and I noticed an issue with the main image not on top.  The right preview is still on top when the pinch starts.  Below is my simple markup

    <telerikPrimitives:RadSlideView
               ItemsSource="{Binding Photos}"
               SelectedItem="{Binding CurrentPhoto, Mode=TwoWay}"
               ItemRealizationMode="Default"
               AdjacentItemsPreviewMode="Both" IsLoopingEnabled="True">
               <telerikPrimitives:RadSlideView.ItemTemplate>
                   <DataTemplate>
                       <telerikSlideView:PanAndZoomImage
                           Source="{Binding BestResolutionAvailableUri}"
                           ZoomMode="Free"  />                  
                   </DataTemplate>
               </telerikPrimitives:RadSlideView.ItemTemplate>
           </telerikPrimitives:RadSlideView>

    Hello Mike,

    I can confirm that this is an issue within both RadSlideView and PanAndZoomImage. Unfortunately, we are not aware of an existing workaround which can be useful in your particular scenario.
    It is in our plans to work extensively on fixing this issue immediately after our official Q2 2012 release (scheduled for the middle of June). I'll let you know as soon as we manage to fix the issue. Meanwhile, let me know if you have further questions or comments. In addition, I've updated your Telerik points accordingly. 

    Kind regards,

    Best work around is to turn off preview :)  I wanted more of the default wp7 photo viewer look anyways.

    Always good to know it's not related to any of my code.

    Thanks

    Hi!
    What we did in our solution is following:
    We added a behavior to the PanAndZoom which basically adds AssociatedObject (PanAndZoom control) to the shared WeakReference<PanAndZoom> list;

    On the page itself, we subscribe to the SlideView.SelectionChanged event and in the handler we walk over the collection and reset .Zoom and .Pan properties of all alive controls inside.

    The homework for everybody is to find out when and how to handle that collection so it doesn't bring any memory-troubles ;)
