You can load any external url into a splitter pane if you specify the ContentUrl
property of the RadPane control. You can disable the scrollbars of the loaded page
by setting the Scrolling property of the RadPane to none.
If you want to use the pane with external content from the other links in your page
you can set the target property of the link to be the same as the ClientID
property of the pane that is used to display the external content.
