Program stop working on mouse move (Hoover) when change data in SfDataGRid

[Sabian Sirius]

Hi,

I am writing about this again because I rewrite code (and whole program) from .net framework 4.8 to .net 8. Code is written in vb.net using winforms controls. I was hoping that the problem is connected with my laptop or with framework 4.8. So, I reinstalled Windows 11 and Visual Studio and SQL Server and Syncfusion winforms controls. 

But I faced same problem. When I change data in SfDataGrid (read from SQL Server SP to show more or less rows) program stops if I move from controls on the left side of the form (where are the radio buttons for choosing what to show) to SfDataGrid area. It is interesting that this break shows when I enter the area on the lower part. 

I noticed that this is not occured always. Mostly it happens when I enter area with mouse fast. If I wait for a few second error doesn't show up.

Also when I change settings for ToolTips (True or False) error is changing.

To be clearer I added images form my laptop and videos in file below. There are images and videos for settings for  ToolTips FALSE and TRUE.

Please can you help me to resolve this problem.

Anything you need more for finding solution I will send you.

Thanks in advance

Sabian

Hi Sabian Sirius,

We have reviewed your query. Based on the details you provided, we prepared a sample to replicate the reported scenario in a .NET 8 environment using VB.NET. However, we were unable to reproduce the issue on our end.

The SfDataGrid behaves as expected, and we did not encounter any application crashes or unexpected behavior when interacting with the grid area, even when moving the mouse quickly.

We have attached the sample for your reference. Kindly review them. To assist you further, we request the following additional details about your scenario:

Customizations: Have you applied any customizations to the SfDataGrid? If so, please share those details.

ToolTip Settings: Since you mentioned that the issue varies based on the ToolTip settings, could you explain the ToolTip settings and share the details about how you applied the ToolTip settings in your code?

Modified Sample: Please modify the attached sample to reproduce the issue on your end and share the updated version with us. If possible, provide a video reference as well.

Providing these details will help us better understand the issue and offer a more accurate and effective solution.
