We are using UltraListView with "Infragistics 17.2" version on Windows Application.
We are facing slowness issue, when we apply GroupBy on data. Initially, we were using "Infragistics 10.1", which was working fine. Later on upgraded to "Infragistics 17.2" which is leading to slowness issue.
We also tried using "Infragistics 18.2" version, but same result.
Is there any issue with latest release? If so, please let us know any way to fix the same.
Thank you for contacting Infragistics!
The best way for us to assist you is if you provide a small isolated sample that we can run and use for debugging locally. If you are unable able to provide an isolated sample I may be able to give suggestions if you provide the code for your page.
I have attached sample project with Infragistics version 18.2. If we add references of 10.1 version then group by works faster than 17.2 and 18.2. Please let me know if anything else is needed.
Please let us know if there is any update on this ticket.
