displayItemsExpanded calls ADG. expandAll() method, for which the source code
is available
I have checked that all the variables involved in that method are either
protect or mx_internal,
So you could probably subclass ADG and write a variant (eg. expandUpToLevel())
to do what you expect.
(hint: extend the test if (isBranch(item) && !isItemOpen(item)))

-------------------
Source code:
public function expandAll():void
{
if (dataProvider is IHierarchicalCollectionView && iterator)
{
// move to the first item
iterator.seek(CursorBookmark.FIRST);
while(!iterator.afterLast)
{
var item:Object = iterator.current;
// open the item if its a branch item and its not already open
if (isBranch(item) && !isItemOpen(item))
{
IHierarchicalCollectionView(collection).openNode(item); //
open node
// dispatch ITEM_OPEN event
var itemRenderer:IListItemRenderer =
visibleData[itemToUID(item)];
dispatchAdvancedDataGridEvent(AdvancedDataGridEvent.ITEM_OPEN,
item,
itemRenderer,
null);
}
iterator.moveNext();
}
itemsSizeChanged = true;
invalidateDisplayList();
// seek to the correct position
iterator.seek(CursorBookmark.FIRST, verticalScrollPosition);
}
}

Objet : Fwd: Expanding ADG to particular level
i,
I have AdvancedDataGrid with multi level GroupingCollection2 which shows 1000s
of rows.
I am using displayItemsExpanded="true".
Is there a way not to expand it not all the way up, but to the particular level
of grouping,
lets say to level 1 programmatically ?
So in that case user will see 100s of 1st level groups (each having 5-10 rows
inside).
That makes a lot of sense and convenient to users.
How can I do that?
Using Flex 4.5.1 with Flex3 ADG.
TIA,
Oleg.
