    I have a RadMediaPlayer as the content of the RadWindow and when I resize or move the window while the video is playing it's very slow.  I did myself a dragable and resizable window which is very very smooth while doing this.  Is there any explanation ?

    You can try it here : http://gearworld.dyndns.org:8082/?VIDEO=1&PL=4
    Open between 6:00am and 8:30pm

    Here's the code :

    RadWindow rw = new RadWindow() { Width = 987,   
                                     Height = 675,   
                                     Header = "Vidés publiques...",   
                                     Content = ep,   
                                     WindowStartupLocation = WindowStartupLocation.CenterScreen,  
                                     MinWidth = 100,  
                                     MinHeight = 100 };  
    rw.Show();  
     

    ep is the RadMediaPlayer

    After reflection.  It could even be the RadMediaPlayer which the performance is bad since with my window I was using the ExpressionMediaPlayer

    I don't know I would have to test all this

    Marc, I wanted to suggest to see if you could replace the RADMediaPlayer with SLMediaElement to see if the cause is the mediaplayer or the RADWindow!

    Hi Marc Roussel,

    RadMediaPlayer is build on top of Silverlight MediaElement and about performance it should be the same. The only difference could be that RadMediaPlayer has some additional controls. With the up coming release it'll have new version of RadMediaPlayer, so you can test it.

    There is a bug with iframes and silverlight.
    Radwindow is an iframe.
    This is not being addressed by Microsoft and it affects all the major browsers.
    If you want excellent performance pop it in anothe r tab or window rather than an iframe and you will feel much better!
