    Hello Grigory,
    Thank you very much for your feedback!

    Could you, please let us know what is the memory capacity of the phone? In addition, are you able to reproduce the issue with another popup example (ex: AutoCompleteBox's examples)? I'd be glad to assist you further.

    All the best,

    Hi Ivo,
    Nope, im unable to repro it with any other control. I've tried AutoCompleteBox and all Date/Time pickers.
    But it was quite easily reproduced in DataForm example (From/To fields).

    The phone is Samsung Omnia W with 512 RAM, but this is also reproduced on emulator (even easier than on the phone, probably coz its a bit faster).

    BTW, i only tried to repro in Single selection mode. Probably other modes are Okay.

    Hello Grigory,

    Interestingly, we are not able to reproduce the issue on our side in any way. It will be difficult for us to determine the reason for it without reproducing it so it will be great if you try to isolate the issue in a separate project and send it to us for further investigation.

    Let us know should you have further questions.

    All the best,

    Hi Deyan,

    Im using Telerik example app Q1 2013.
    I think it is the best repro.

    Reproducing is a bit tricky. 
    1. Open ListPicker example page 
    2. Open "Reminder" listPicker.
    3. VERY QUICKLY select some item

    4. If the bug isn't reproduced -> Exit to control list and go to step 1.

    Important: Don't try to reopen "Reminder" listpicker after failed repro. It is important to reopen page.

    Hi Grigory,

    Thanks for writing back and for the further details.

    I would like to inform you that we've been able to reproduce the issue.

    It does not seem easily reproducible and we will continue investigating it.

    I have updated your account with 1500 Telerik points for bringing our attention to this issue.

    As soon as we find the reason for it, we will fix it.

    We will consider this thread closed for now.

    Let us know as soon as you have further questions or need assistance.

    Kind regards,
    Deyan

    Probably this RadWindows issues is connected. IIRC ListPicker uses RadWindow

    Hi,
    I've found the issue. 

    RadWindowWP.cs RestoreApplicationBarOverride()
    It should looke like that
    protected virtual void RestoreApplicationBarOverride()
           {
               IApplicationBar windowAppBar = this.currentAppBar;
               if (this.isAppBarModified)
                   this.HostPage.ApplicationBar = this.defaultAppBar;
               if (this.appBarInfo != null && this.isAppBarModified)
               {
                   this.appBarInfo.RemoveEventHandlers(windowAppBar);
               }
     
               this.isAppBarModified = false;
           }

    I've added line 'if(this.isAppBarModified)'. This fixed the issue.
    You code is removing page appbar only after animation has played, and i can close picker BEFORE animation has player.
    So the appbar in this.defaultAppBar is null. And the code is setting to page.

    Hi Grigory,

    Please upgrade to the latest release. The bugs you reported in RadWindow should now be fixed. Can you please update your dlls and confirm that everything is ok. Also, the context menu is updated and now contains the OpenFailed event.

    Regards,
    Victor

    Fixed issue in my local source of Teleriks and published app with it. 
    For Control users - feel free to implement the workaround that is few messages higher.
    Mark as solved.
