I've a hierarchical RadGridView I populated withtwo Datatables in a Dataset with Data from a sql Table.
I've applied the Material-Theme.
In the default theme everything works fine, but with the applied Material theme after a few expansions, the grid suddenly gets white and after scrolling has its data again but at the top there is a random white space suddenly.
I'm suddenly tesing with the trials version, but don't think that's tthe reson for the problem.

Thank you for the provided images.
Looking at the MergedDictionaries, the Navigation.dll is not merged. My guess here is that is the reason behind this behavior. You can add a reference to the Telerik.Windows.Controls.Navigation.dll and merged it in the Application resources. Check the following code snippet.
Give this approach a try and let me know how it goes on your side.
Sorry for the late response, I had holidays for 2 weeks.
I added your snippet, but sadly the behaviour is still the same.
After testing, I can say, that I have the same thing with the Office 2016 Theme...
I now uploaded my VisualStudio project here: https://www.dropbox.com/s/hiuw1m7rn0hmj9s/KEMlogTelerik.zip?dl=0. Caused by the database connection ysou won't really be able to debug it but maybe see a problem in my code.
I can now say, I have the reason for my problem. Sadly no solution.
If I have a column with HeaderTextWrapping="Wrap" these strange behaviour appears. And also if the childtemplate has ShowGroupPanel="False".
I could live with the TextWrappping, but the ChildGroupPanel makes the table way too big to work with it...
I am happy to hear that GroupRenderMode property works for you. If you have any other questions, you can open a new thread with your questions inside.
