RadPageView ContentURL

[Kent]

Im having some trouble getting the contenturl in the radpageview to work (towards the bottom of the snippet).  I am following a guide on the telerik website with a few additions of my own.  On the third tab it should display the telerik website, but all I am seeing is 'This text is never shown'.

Any advice?
