I have a GroupingCollection whose source is an ArrayCollection. Then have an advanced datagrid who's dataprovider is the GroupingCollection. This gives me the expand collapse.
The ArrayCollection is populated by a real time event which fires every (x) seconds. At that point I do a gc.refresh(true). The problem is, that when the refresh is fired, it collapses any folder that was expanded in the datagrid. Does anyone know how to maintain state of the expanded Category? I have tried to do Datagrid.ExpandAll(); as a test, but did not seem to work. Sample code would be great. Or if anyone can think of a better way of doing...also please let me know...thanks -greg Thanks in advance.
