I use RadTabControl and RadHtmlPlaceholder control inside each tab.
If I point RadHtmlPlaceholder to the page with the plain html everything is ok.
When I point RadHtmlPlaceholder to the page with WPF application inside (for example http://demos.telerik.com/wpf/
) and switch tabs, content disappears.
I've tried some advices from other threads like set RadHtmlPlaceholder visibility and update layout when switching tabs, but no luck.
Any ideas ?
