Grid paging with big groups

[Pierre]

Hi, maybe we do not use the grid correctly.

We got a collection of 2000 items. The DataSource is local.
 If we what a fast and responsible grid we have to use paging (changing theme, reloading grid take long time when 2000 items are displayed Ethier with scrollbar on the grid). So we set the paging at 50 items/page.

But with paging On, grouping are useless for us. When grouping start, I collapse all groups to let the user open the one he need. But if the first group contain 400 items, all other groups do not show in the list. To show all group I must set the paging to 2000 and then slow the grid process.

Any suggestion?

Hello Pierre,

I am afraid I cannot offer you a work-around to this scenario.

The Grid displays as many records as there are - no matter how many groups there are (even if they are collapsed).

Is this issue fixed for 2016? Does kendo ui grid support the desired behavior tha Pierre mentioned above now?

Hello Ning,

Grouping and paging work together in the same way as they did previously - first, paging occurs, and then grouping. As a result, when a group is collapsed, the user does not see the next groups. Also, if a group size is larger than the page size, then it spans across multiple pages.
