GroupRenderMode=Flat and ColumnAggregatesAlignment=NextToGroupKey combination freezes the GridView while grouping

[Mustafa Erhan]

Hi All,

When we use GroupRenderMode = Flat and ColumnAggregatesAlignment=NextToGroupKey together makes the application freeze while user grouping the gridview. Our gridview has 3K rows and 15 columns. 

When we remove ColumnAggregatesAlignment property, everything is fine. But the aggregates looking very ugly at headers.

Is there any workaround about that ? 

 

Thank you.

Hello Mustafa,

I tried to reproduce such performance degradation with the reported setup, but was not able to do so. Can you please take a look at the attached sample application? Does it differ in any manner from the setup you are using? Which is the assemblies version that you are using? Also, would it be possible for you to modify it so that the problem is reproduced, open a new support thread and attach the sample application in it?

Thanks in advance for your cooperation.

Hi Stefan, I was using "2017.3.1018.45" trial version, now I setup "2018.2.515.45" licenced version and it looks like it solved. I will try for more, and will write if there is still problem.

Thank you.
