    Hi,

    i noticed 2 problems with the Beta 2 bits:

    When tested on a HTC Trophy, the animation of the individual items in the popup screen does not play (or at least cannot be seen) the first time this popup opens. After reopening the same popup from the ListPicker, the animation plays fine. Seems like there's too much loading going on during the first time.

    And I noticed that in Expression Blend, the "Popup Header" input field is disabled at design time, you cannot input text there. After I go into the XAML and add property manually, the textbox gets enabled as it shoud be from the beginning. The "Header" property on the other hand is correctly enabled for input from the beginning.

    cheers,
    Bernhard

    Hi Bernhard,

    Thanks for writing and sorry about the delay with our answer.

    I have performed some tests with the RadListPicker control by creating a sample Windows Phone 7 application and putting an instance of the control on the main page. The animations seem to work fine for me. It seems that the case that you report is not always reproducible and occurs under some special circumstances. Therefore it will be extremely helpful if you manage to give us some further details on how we can reproduce the case (the XAML structure you are using or sample app).

    As for the issue with the PopupHeader property of the RadListPicker in Expression Blend I would like to inform you that we have been able to reproduce the case and we are investigating the reason for it. We will provide a fix for it as soon as possible.

    Thanks for your time and do not hesitate to get back to us in case of further questions.

    Kind regards,

    Hi Deyan!

    I upgraded to the final release and tested again. The problem seems to be gone now. I just noticed that when the debugger is attached, the animation sometimes, but not always, is played only half part, means starting from the middle of the list, so the first few items are skipped. When I run the app without an attached debugger, it nearly always run fine, just in very few tests I could noticed that a little bit of the beginning of the animation is skipped.

    Anyhow, with the final bits, it is fine now, that animations not always (= 100 % of the time) run fine is unavoidable in WP7 IMHO.

    If you want to test anyhow, you can use my feed7 project to test I sent you for the DataBoundListBox testing, on the settings screen, there are 3 RadListPicker controls.

    As for the Expression Blend bug, that's not so important, I can always change this property in XAML, but of course it would be nice if this is fixed in a future update.

    The whole control package is now really great ... its far superior in any way to the native controls or the Silverlight Toolkit controls. A few issues are left, but I'm sure they will be fixed soon :)

    cheers,
    b.

    Hi Bernhard,

    I believe that these animation issues that you experience are most probably related to the fact that the debugger is attached and a constant synching between the phone and Visual Studio is performed which hits the performance for sure.

    Anyway, if you notice any kind of wrong behavior do not hesitate to let us know.

    Thanks for your time.
