Hi
I have a RadGrid with Grouping, Collapse and Expand functionality.
That works very well.

My problem:
When I click the command "Edit", edit mode = "popup", go to Collapse and Expand selections lost.
What can I do that the users stay with selection Collapse and Expand exist forever?

Sorry for my bad English

Hello Rolf,

Please take a look at the following code library which explains how to persist the groups expanded/collapsed state in RadGrid.

Thanks.

Is there anyway then to have the collapsed grid treated as 0 or 1 item, so 9 or 10 more items show from the next group if the page size of the grid is 10? In other words, can the grid ignore collapsed groups in the item count?

Hi Peter,

I am afraid the grid generates values only for the items on the current page. Therefore, the items on the next page are not available at the current time. This behavior depends on the RadGrid implicit grouping logic and currently there are no scheduled plans to modify this behavior.

I hope the clarification was helpful.

Kind regards,
Eyup

No worries Eyup - we haven't had any issues so far - I can just see a user asking about this behaviour one day :).

Problem still exist. I refuse to put in tons of ugly code as workaround!

Hello Frank,

You can examine the RadGridGetAllSelectedItemsImproved.zip sample provided in the following post and see the implementation demonstrated there:

I hope this will prove helpful.
