Hi Erik Damgaard,

We are aware of this issue in the RadHtmlPlaceHolder when hosted in ChildWindow. We highly suggest you to use RadWindow instead of ChildWindow in this scenario. Please let us know if you need further assistance. We would be glad to help you further.

Hi Oded Zadok,

Try setting the KeepContentInMemory property to true:

<telerik:RadWindow x:Name="window1" Width="500" Height="500">
    <telerik:RadHtmlPlaceholder SourceUrl="http://www.google.com" KeepContentInMemory="True" />
</telerik:RadWindow>

 
Let me know if this helps.

Hi,

I've done it already, but isn't solved to problem.
It's append when you have more the one RadWindow (none modal...) opened.

For example try to open a RadWindow which contain a RadHtmlPlaceHolder and second RadWindow in a none modal.
When u change focus between the RadWindow's the RadHtmlPlaceHolder will be removed from is host.

It's seem like the RadWindow Control clear is content, when there are more then one RadWindow open.

Oded.

Hi,

The KeepContentInMemory="True" && fixing a bug of my solved the issue J

Buy it seem like there is a problem when RadWindow host MediaElement or RadMediaPlayer Control.

For example:

 - Open FIRST RadWindow which host MediaElement and set the Source to some WMV file (URL)

 - Open Second  RadWindow which host MediaElement and set the Source to some WMV file (URL)

Try to change the focus between them, the media start to play from the beginning each time you focus on some RadWindow

Thanks,

Oded.

Hello Oded Zadok,

The RadWindow uses a Popup internally and this Popup reloads its content every time it has been clicked which is a common Silverlight issue actually. The good news is that we have re-factored the RadWindow and it does not use Popups already. I tried your scenario with the our latest development version of RadControls and the issue was gone. You will be able to use this re-factored RadWindow with the upcoming Q2 Official Release scheduled for 13 July.
