First of all, my issue is about RadTabControl and RadHtmlPlaceholder.
In fact my scenario is quite simple. I have 2 RadTabItems with a RadHtmlPlaceholder as content template. Each time I select a tab and then come back to the previous tab, the sourceUrl of the embedded RadHtmlPlaceholder is reloaded. It means that if I made some actions on my webpage like entries in a form, I loose them everytime I change tab. I tried to set the IsContentPreserved property to true, however nothing changes about my issue.
I hope you will help me,

Could you please tell me when I can expect this fix?
In fact, I have just noticed that the issue is more general.
I defined my tabControl with the following contentTemplate :
Each time I select a tab and then come back to the previous tab, the state of the page is lost. It's not only about RadHtmlPlaceHolder but every Silverlight views. My tabControl is defined like this :
I used your code to test the reported general behavior but I wasn't able to reproduce it. The state of the tabs is preserved when using a Frame or any other SL UIElement. Can you try setting the SupressSelectedContentTemplateReapplying property of RadTabControl to True and see if the issue still occurs?

It's been more than two years that I opened this thread and I still have no update about that very annoying issue.
