This is indeed very odd behavior - the sliding panes should be as high as the splitter. We are not aware of such problem and you are the first one to report it. However, the provided screenshot is not enough to determine the exact cause of the issue. Could you please provide more detailed information on the specific scenario?
- Which version of RadControls for ASP.NET AJAX and .NET Framework are used in the application?
- Under which browser and its version the problem occurs?
- Could you please provide a simple fully runnable project reproducing the problem so we can investigate it further?
All the best,
the Telerik team
