Hi Telerik Team !
I would like to know some thing about the grouping in the radgrid !
Some Days ago, i have a big grid with 1000+ rows and the load of this page was very long ! So boring... not cool
So i now put a group by one field and groupsdefaultExpanded property of the mastertable at "false".
It seems the page load is faster but it is always more than 10sec ! And the display is only 4 or 5 groupheaderitems, so it is too long
So my question is : is the grouping load data and don't display it ?
If yes, is there a way for load data only when i expand a group ? If not, why the time is so long and can i load quickly my grid
Thanks in advance !

Grouping still requires all of the entries to load, from what I know (I could be wrong though). You could look into using LINQ like in this demo, that might be able to help you with optimizations quite a bit. Using .NET 3.5 and LINQ should improve performance.
