We are restricting a search to 500 and then doing grouping by a column.
This column has less groups, but each group has 100 + entries.
The grouping functionality works fine when we have lot of groups with less number of children, but with few groups and a lot of children to each group is causing performance hit.
We are using <telerik:RadGridView.GroupDescriptors> for grouping
Can anything be done to imporve the performance?

Hello,

Generally you will get performance issues when the GridView is grouped, because the data virtualization is off. In that case the GridView is aware of all the items. Improving the performance is an on-going task and we work on it.

This is a really annoying issue. I suspect there's something else than virtualization. I have a GridView grouped by a property by default with about 20 rows. Setting AutoExpandGroups property to true causes filtering very slow.
I hope you can solve this issue as soon as possible. Unfortunately, I'm not very optimistic as I've seen the this Issue is open in PITS but not scheduled yet.
