CheckBox header renderer with HierarchicalCollectionView
- by fumeng
Hi -
I've gotten a checkbox header renderer to work well with flat DPs, but a
hierarchical collection view is another story. On click, I want it to select all
checkboxes in a given column. Here is my code:
var dp:HierarchicalCollectionView = _dataGrid.dataProvider as
HierarchicalCollectionView;
var testDp:GroupingCollection = dp.source as GroupingCollection;
var rawDp:ArrayCollection = testDp.source as ArrayCollection;
for(var i:int=0 ; i < rawDp.length ; i++){
rawDp[i][_dataField] = cb.selected;
}
It selects all checkboxes on the 2nd level of data, but doesn't select the top
level of data. What am I missing here? I can't seem to find it.
Any tips are greatly appreciated. Thank you.
