Hello, Saud,   

The ViewMode property allows you to control the current mode of RadPageView. The supported modes are Strip, Stack, Outlook, ExplorerBar, Backstage and Navigation view. Feel free to use this one which suits your requirements best.

In order to allow the end users to change the view, you can use a RadDropDownList for example, fill it with items illustrating the different view modes. After the selection is changed, set the RadPageView.ViewMode property to the respective view.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
