    I have a RadDataBoundListBox that is bound to an ObservableCollection<T> in my markup.
    The ObservableCollection contains anywhere from 1 to 1500 items that are downloaded remotely from my server and added to the collection at a rate of 50 items per remote call.  There's only about 50 items in the Viewport at any time.  Each item may or may not contain an image.
    Here's the problem:  when I select an item, which should cause the application to redirect to a different page within itself, if the RadDataBoundListBox has not completed populating/rendering/animating, the whole thing just stops.  Frozen.
    Now, my question is, am I doing something wrong or is this just an scenario for which using this animation is inappropriate?  Any thoughts?

    Edit:  This seems to only be a problem in the Emulator.  I don't see the problem when running the app on a Device.

    Hi Jason,

    Thanks for writing and for the provided details.

    This does not sound like a correct behavior. Can you provide us with a sample project that can be used to reproduce the issue so that we can investigate it? Please note that you will have to open a new support ticket in order to be able to upload your project.

    Thanks for your time.
