Group open/close

[acarur01]

Is there any way to dynamically open/close the groupings in a listgrid?

[Isomorphic]

There's the "groupStartOpen" property controlling which groups are initially open. There's current no API to open or close specific groups later on.

[Isomorphic]

On second thought, this is not true - the groupTree is available as grid.groupTree, which means you could call tree.openFolder on it.

[acarur01]

Yup. Ive tried groupStartOpen but cannot change later on. I will try the tree.openFolder

When changing the data of the listgrid, groupStartOpen property is not retained. Please verify that this is a bug - Click the button to change data of listgrid in the sample

Yes, this is a bug. Among other workarounds, you could ungroup and re-group:

companyList.ungroup();
companyList.setData(testData2); 
companyList.groupBy("category");

Thanks. I will be upgrading to a later nightly build soon. Please let me know when this is fixed.

[Isomorphic]

This is now resolved (on the 8.1.x branch)

[acarur01]

I am still getting some cases where the groupstart property is not retained. I cannot reproduce as a standalone. We have a sort of "manual" paging implemented. I am not sure what to look at to debug in this case. It usually loses groupstart when I go back to a previous set of data. Do you have any suggestions as to what could be happening? What if I provide all the dsrequest/response up to where the groupstart is lost?

[Isomorphic]

It's unlikely to be anything related to specific DSRequests/DSResponses unless the responses are actually invalid, it's more likely to do with a weird sequence of calls. From code inspection, no particular scenario suggests itself - every time we re-create the groupTree, the groupStartOpen property is applied, it's unconditional.

Sorry, but we're probably not going to be able to provide any more help than that until you get a reproducible case.

[acarur01]

Ok. Is there anything I can check in the listgrid when dataArrived is called? What properties are being set? What should I look for in the listgrid.groupTree?

[Isomorphic]

The implementation is the same as what we recommended for manual use - once the groupTree is formed we use the groupStartOpen setting to call openFolder() on the appropriate folders.
