    Hello Support,

    I get this error when I double click the datepicker control to select date.
    I can continue pass the error, I can select the date OK, but I see a flickering transition?/animation? and the screen stays black.


    System.NullReferenceException was unhandled
           at Telerik.Windows.Controls.RadWindow.OnOpenAnimationCompleted()
           at Telerik.Windows.Controls.RadAnimationManager.InvokeCallbacks(Storyboard storyboard)
           at Telerik.Windows.Controls.RadAnimationManager.StopStoryboard(PlayAnimationInfo info)
           at Telerik.Windows.Controls.RadAnimationManager.OnStoryboardCompleted(Object sender, EventArgs e)
           at System.Windows.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args)
           at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, String eventName)

    Hi Craig,

    Thank you for contacting us.

    The problem is that when you double-click the picker it starts an open animation upon the first click and attempts to close (open animation is still running) upon the second click. This causes a NullReferenceException to be thrown, which leaves the window in invalid state and that is why you see a blank (black) screen.

    We have fixed the bug immediately and the fix will be available in our next CTP release.

    I would like to thank you for your time and for reporting this bug. Your Telerik points are updated as a token of our gratitude.

    All the best,
    the Telerik team
