Hi All, I have an AdvancedDataGrid, a GroupingCollection and an ArrayCollection as a source of GroupingCollection.
I update the display by setting a filter on arraycollection and calling refresh. But the AdvancedDataGrid doesnt reflect the changes unless I call GroupingCollection.refresh(). Bad. My ArrayCollection contains only 450+ items but GroupingCollection.refresh() takes too long time to re-render the list. Is there any other way that I can do this faster? and without waiting and repopulating the WHOLE list? for example I just want to hide 1 item by adding it on my filter, the list should simply adjust by deleting that row only (just like how a normal List UIComp+ArrayCollection behaves). Any ideas? -Stephen p.s. I have seen the http://flexpearls.blogspot.com/2008/06/groupingcollection-with-some- better.html but it still re-draw the whole thing and doesnt keep the state of the list (expanded/collapsed).
