I'm sorry, I can't write english well.
My question is...
On a few data in datagrid, groupby function is fast, but on much data in grid, groupby operation is too slow.
That is same, when turn in or off groupby function.
Let me know how to make tune datagrid. ^_^
Hello,
It has been a while since you have made your post, in case you still need support I will be glad to assist you further. I suppose the other community members can benefit from this answer as well. So I have been looking through your post and I can say that this behavior is expected for large number of date, because when you make group by, every new group represents a Record and this is the thing that takes some time before the groups are rendered on the UI.
Feel free to write me if you have further questions.
