Hi Nevron Support,

I would like to report a problem with a possible memory leak encountered when using NDrawingViewControl in WPF application.
Here is my setup:

Sample Application:

This is a simple WPF Application (.NET Framework 4.7.2, using NOV version 24.6.3.12).

When I open then close the PageDialog, my memory consumption does not decrease.
I am also forcing the call to the garbage collector on PageDialog.Closed event.


Here is my CustomCanvas class


I also checked memory leaks using JetBrain's dotMemory profiler to confirm if memory leak occurs.

I hope I was able to explain well the details of this possible issue.

If you want to check my full demo app, please provide details on how I can share my source code with you.


I hope you have already a solution for this issue.
I would appreciate it if you can share the solution with me.

Thanks.

Hi Jan,

Thank you for the detailed description of the issue and the screenshots. It would be great if you send us a sample project that demonstrates the issue. We will then be able to debug it and tell you what's wrong and how to fix it. You can add a ZIP archive with your project to a new comment in this forum topic or upload it to a cloud service of your choice and send a download link in a new comment.

Thank you!

Best Regards,
Nevron Support Team
