Consider Internet Explorer 9.0 (and possibly other browsers too). When you start dragging a tab you get the possibility to detach it from the main window and move/drop it into what becomes a new main window.

Can this be done using RadTabControl?

Hi Kristoffer,

The RadTabControl doesn't support this scenario out-of-the-box. However, you can use the DragDropManager to create a custom drag/drop logic that creates a new Window when a RadTabItem is dragged and dropped somewhere in your application. The specifics of this implementation will depend on your particular scenario.

Let us know if you need more information.

I have a similar question. How can the drag the ItemTemplate and ContentTemplate to be displayed as the dragVisual

when a drag and drop is intimated from the tabcontrol?  I can get of them being displayed as shown below.

But how can  I get both of them?

  args.DragVisual = new ContentControl
                                  {
                                      Content = data,
                                      ContentTemplate = (sender as RadTabControl).ContentTemplate
                                  };
