Hi Deepak,
Thank you for getting back to us! We're not aware of any memory leaks caused by the controls you listed. This is why I wanted to ask you if you can try to isolate the issue in a sample solution and attach it in a new ticket. I also noticed in the snapshots you sent that you've referenced the Diagrams assemblies so I was wondering if your solution utilizes RadDiagrams as well.
If you can send a solution where the leak can be reproduced, we will gladly further investigate it to find what causes the leak.
Thank you in advance for your cooperation on this matter.
All the best,
Tina Stancheva
