I don't really understand your question, but I think your asking if you can load dynamic content when a tab is clicked without re-loading the page. You could do it using Ajax, where the tab postback will load the content in div or panel.
The other solution would be to add a RadMultiPage and associate it with the RadTabStrip. Then you can create the page view for every tab you create, add the user control to the page view's controls collection and add them to RadMultiPage. Then when a tab is selected it will display the associated page view. Just to remember to have RenderSelectedPageOnly set to false, or it won't load all the page views.
Hopefully that's what you wanted.
