Flex Advanced data-grid grouping
Hi, we need to create an application prototype for a company that need it
for a demo.
the application has loads of grid and most of them are grouped like the one
i attached here... see the groping "+" buttons on the left ....
So i was looking for the possibility to obtain the pretty same result in
flex... i found this:
http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-7bf4.html
and in general i think we will use the advanced data grid control...
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/mx/controls/AdvancedDataGrid.html
but the question is: is the component still usable in the very new version
of pache Flex? are there any new component to do this?
Thank you vey much

I'm not sure but I think that the ADG wasn't modified anymore.
I've just done a simple test using the ADG and GroupingCollection2.
I've loaded a flat collection of 10.000 items by querying an ElasticSearch
instance, convert the returning JSON to an AS3 ArrayCollection and use it as
source of the GroupingCollection2.
Of course loading the data takes a few seconds but populating the ADG was
done in milliseconds.
Opening and closing the created groups/folders could be done without delay.
I've displayed 6 coumns inside the ADG.

If you'd like to use the <s:DataGrid> there might be some issues cause you
have to provide
IList as dataprovider:

I'm using a commercial product "Flexicious Ultimate" since a few years.
Probably it provides most of the features that you would like to have out of
the box (Including LazyLoading). The fee is more than fair and the support
of these quys is awesome.

Hope this helps,
Olaf

Hi Angelo,
I can't answer all of your questions. My experience with advanced datagrid grouping is that in order for the tree and expansions to work, you need ALL layers of data in the beginning. So depending on the amount of data that your grid encompasses, that may not be very friendly on your database.
What I have done in the past is to create a repeater that looks like a datagrid. It queries the database for the outermost layer, and then queries again as each row is expanded, and ONLY if the row is expanded.
Additionally, (this is coming from flex 3 usage so it could have easily improved since then), if your datagrid has more than one layer of expansion, it has some very odd glitches after several row openings and collapses.
