    Hi,

    I've got a strange behavior when i use the coverflow in a prism region.

    I show the coverflow in a region, when the user select one item, i perform an animation that hide the view in the region where the coveflow stay (i keep it alive and still in the region - the view is only hidden), and show another view.
    Later this view is hidden and the view with the coverflow is shown.

    When the coverflow come back, i can select the coverflowitems on the right, i can't select the coverflowitems on the left, and the controls on the selected coverflow seems to be unactive.

    I seriously think that something in my code is craating this behavior, but i ca'nt figure out which part.

    So could you tell me the way i can make the coverflow behave like that :
    * Coverflow items on the left can't be selected,
    * Controls on the Current Coverflow can't be selected,
    * Coverflow items on the right can be selected.

    In addition, if in my code i select the first Coverflowitem, wait a little, and then select another one, the coverflow has a standard behavior.
    But if ii select the first Coverflowitem, wait a little, and then selectagain the first item, the covererflow has a standard has the behavior describe above.

    Thank you for the help.

    Christian

    Hello Christian,

    I am afraid I couldn't get you right. Do you aim to disable the items, or they appear disabled and you are not sure why? If you send us some code snippets and more details about the scenario it will be very helpful.

    Looking forward to your reply.

    All the best,

    Hello Konstantina,
    Thank you for the answer.

    In fact, i don't understand why a part of the Coverflow does not react as expected.
    The selected item and the items on the left seem to be inactives.

    I am looking for the causes that can make the CoverFlow respond as follows:
    - A click on the items on the left does nothing
    - The controls of the selected item appear to be inactive (they do not respond to clicks)
    - I can click on the items on the right, and the CoverFlow react normally.

    After clicking on an item on the left (change selected item), all the coverflow acts normally.

     If you have no clue, I will try to reproduce the problem in an extract of the applicaton.
    But it is not sure that I'll reproduce the problem.  I use CoverFlow in other parts of my application and it reacts normally to the change of view with Prism.

    All the Best,
    Christian

    Hi Christian,

    If you are able to reproduce the issue in a sample application and send it to us, it will be really helpful for tracking down the source of the problem. I tried to reproduce it also, but to no avail. We haven't received reports for such issue, so I cannot give you a possible clue at the moment, what might cause this strange behaviour.

    All the best,
