    Hi,

    We found that all pop up (both microsoft and telerik) controls become very slow when design is very complex and uses numerous of shader effects. However the rest of application works normally.

    Do u think it is caused by shader effect or there is another reason?

    Look at DatePicker on our site http://househotel74.ru/#/Booking.

    Thanks,
    Alexey Zakharov.

    Hi Alexey,

    We are sorry that you are facing such a problem. Actually we have never received requests regarding the performance of the RadDatePicker. It would be nice if you share some more information about the design of the application in which the RadDatePicker is used. Also you can try removing the shader effects or any Silverlight Toolkit implicit style manager, if you are using the features. Also you can try switching off the animation of the RadDatePicker before loading the control:
    Telerik.Windows.Controls.Animation.AnimationManager.IsGlobalAnimationEnabled = false;

    Kind regards,

    Hi,

    I've reproduce bug with standard datepicker. But telerik will have the same problem.

    Here is the link to the sample project, which illustrate bug.
    http://weblogs.asp.net/blogs/alexeyzakharov/SilverlightApplication2.zip

    As I suppose it is shader effects.

    Are shader effect doesn't use hardware acceleration?

    And ideas?

    Best regards,
    Alexey Zakharov

    Hello Alexey,

    Unfortunately, the Silverlight shader effects do not seem to use hardware acceleration. We have similar problem with the Q3 CoverFlow - it uses shader for the item reflection and when the items become very large, the control suffers from large performance penalty.
