Hello Alexander,

Thank you for contacting us.

To achieve this scenario, you can set Padding to the ItemsPanel of RadPageView and then place a RadPanel in the free space. I am enclosing a sample project which demonstrates this. I am also attaching a screenshot which demonstrates the settings you need to make. Note that RadPageView does not allow child controls of types other than RadPageViewPage. Therefore, I have added the RadPanel to the free space on the form, used the Bring to Front menu item from the context menu, and then used the arrow keys to place the panel properly. This way the panel is added to the form's child controls but it appears over the page view.

I hope this will help you. Do not hesitate to ask if you have further questions.
