I have a custom RadMediaPlayer template that adds a button to the player's control bar, which creates a RadWindow when clicked.  This window will allow my users to view and edit additional information about the video that is playing.  However, when the RadWindow is created and shown, any further interactions with the player cause the entire player to be unloaded and reloaded.  Are there any easy workarounds for this issue, or do I need to use a different control for this?

Hi Mark,

I added a RadButton in the RadMediaPlayerWrapper default ControlTemplate and handled its Click event to open a RadWindow control. However,. I wasn't able to reproduce the issue you described. Can you please have a look at the attached sample and let me know if I'm missing something. Also, can you tell us the list of steps that lead to reproducing the issue?

Thank you in advance for your cooperation.

Hello Tina,

Thank you for your reply.  Using your sample, I have been able to determine that this issue seems to only happen when the MediaPlayer is contained in a floating RadPane, which is necessary for our application.  I have modified the sample project you provided to demonstrate this, and since I cannot upload the project the modified XAML is below.  Leaving the window docked as it is initially, if you press play, click the button you added, and then press pause, it behaves as expected.  However, if you make the window floating and do the same thing, pressing the pause button causes the MediaPlayer to unload, reload, and begin the playback of the video at the beginning.

I never heard back from anyone regarding this issue, so I am wondering if there are any known workarounds or plans to resolve this.

Hello Mark,

 Please accept my apologies for not replying as I had promised before. We did not find a workaround for this issue and we logged it as a bug in our RAdMediaPlayer . We also updated your telerik account points as a thanks for your cooperation.
