To reproduce:
- Add RadPageView with a two pages to a blank form, each page should contain a RadGridView.
- Populate the gids with some data.
- Start a gotomeeting and show your screen.
- Launch the application or start debugging.
- Add a column to the first tab page (not sure if the location or placement matters)
- Click the tab header for the second tab page to try to navigate to it
-  Nothing will happen.

Workaround:
- Change focus to another application.
-  The test app will now update.
