I have a real simple grid prototype. Works fine until I group by a column. When any grouping applied the area below the header row is blank although the gridview seems to be resizing as expected. I think this is a rendering issue.
- Windows 10 OS
- Dell PC
- Latest Telerik, installed today (trial)
Images attached show the before and after. Notice that the size (border) of the grid changes as expected.

Since I posted I've been seeing an exception in the VS2017 designer pane:
Thanks for the detailed explanation.
Can you please clarify whether any styles are applied to RadGridView when the control is being grouped? If this is the case, a possible cause might be that the defined styles are not based on the default theme ones. This assumption will be valid only if Implicit Styles are used. In order to get familiar how to base the custom styles, please, take a look at the Styling the Controls topic. If this is not the case, may I kindly ask you to send me a sample application demonstrating the behavior you are experiencing so I can provide a more adequate assistance? You can take a look at the Isolating a problem in a sample application blog post for further reference.
As to the exception you are experiencing, would it be possible for you to check whether it is reproduced only with VisualStudio 2017? Is the designer behaving as expected with previous versions?
