Hi we upgraded infragistics from 13.1 to 15.2, our client found out performance degraded when scrolling UltraGird with 1000+ rows. The more data shown in a row, the slower it is when dragging scroll bar down the page.
one of the column style is FormattedTextEditor.
We'd like to know if there is any change from 13.1 to 15.2 that affected the performance on scrolling UltraGrid.
Thanks,
Crystal,
Please find enclosed recording that shows the performance difference.

Hello Crystal,
I made a simple test of both samples you provided using the versions, you are using (13.1.20131.2060 and 15.2.20152.2052). The test measures the time for scrolling the grid from the top to the middle and then scrolling back to the top and down again. Attached is a video file of the performed test.
As you will see from the attached file, I still cannot reproduce the issue you describe, so it will help if you could record a video that demonstrates the behavior you are seeing.
Hi Miteva, can you try to drag the scroll bar fast from top to the middle then back and forth a few times? We can see there are differences between the two versions. 13.1 one is more responsive. Can you check the code to see if there is any changes in the area?
15.2 version is 15.2.20152.2052, runtime version v4.0.30319
13.1 version is 13.1.20131.2060, runtime version v4.0.30319
I tested on Windows 10.
Thanks,Crystal.
Hello Crystal, I ran the two samples you provided on my machine and I do not see any difference in performance when scrolling down the grid. Attached is a record of the test I did.
The fact that I was unable to reproduce the behavior you are describing indicates either an issue possibly specific to your environment, or a difference in the DLL versions we are using. So could you please let me know the exact version of Infragistics components, which you are using?
Thank you for looking into this issue, please find enclosed sample projects for 15.2 and 13.1. We are able to see the difference between the two versions. In our application, it's worse.
