Memory leak problem when set the Grid.Style.BorderColor property

[SZL]

Hello,

I noticed 2 problems a long time ago, but only now I had time to find the reasons.

1. problem: When I set the BorderColor property of the grid in Designer.cs file, a memory leak appear. At runtime the GDI objects count increasing every second with 9-10 new items also in idle form too. I can watch the GDI objects count in Windows Task Manager. When it is reach 10000 my application crashing with GDI+ exception. My application always gets slower as the number of GDI objects increases.
   
   Please check attached video memoryleak.mp4
   
   When I remove the BorderColor property from the Designer.cs file, the memory leak not appear anymore.
   
   Please check the sample app and remove line 67. from this file:

WinFormsApp1\Fomenu.NET\Controls\GridContainer.Designer.cs



Can you help me please why this memory leak happen with this property and how can I fix it?

2. Second problem is throwing in designer mode in Visual Studio 2022. When I select the button in designer mode its start vibrating and never stops.

With many objects, the designer will become slower and slower, and eventually it will have to be restarted. Please watch attached video (vibrating.mp4) to see the problem. Do you have any idea why this happen?

Please check the following url for sample project and videos.

Reproduce the issue:

- Start project

- Click on button

- Set focus to grid (if it not enough make a sort)

- Check the GDI object increasing in Task Manager

Thank you for help!

Hi,

Thank you for help!

The second problem is gone in my side too, not understand why, I watch it in the future and I will write to MSDN when occurs again. I wrote here just because with the original NET controls it didn't appear.
