Telerik support,
Replicating this behavior is pretty simple. Not sure why opening individual support cases would be needed since this behavior appears to be the same in any environment, and there are a number of us who need this issue corrected.
Here is a sample code where Views 1 and 2 work just fine (page height automatically adjusts to the full height of the user control without scrollbars,) but views 3, 4, and 5 do not. Views 3, 4, and 5 open in full width, but the height defaults to about 100px or so (just a guess.) The contents are chopped vertically, and are only visible by scrolling up/down. Setting a height of "100%" on either the RadTab or RadPageView has no effect. The only way we have been able to override that is by setting the RadPageView height in pixels (i.e. "800px".) Needless to say, this is undesireable since different pages will require varying content heights.
The javascript function suggested by Veronica (included below) only works partially. Depending on the page being loaded, the scrollbars are still present in most cases, and in some cases even producing double scrollbars.
