Windows Phone Dev. Adding items to Pan-Page doesn't work

Question

I have

   <!--Panorama item one-->
   <controls:PanoramaItem Header="Search">

   </controls:PanoramaItem>

and what I simply want to do, is dropping some TextBoxes etc. into it. But when I drop a Textbox (while the panorama item one-grid is selected), visual studio adds these form items outside the panorama pages, somewhere at the bottom of the XAML.

How can I add forms into the panorama item I decided them for?

Answer 1

A grid. I needed to add a grid, to store all my elements inside.
