Hey Alex could not find the background itemrenderer for
ADG in your blog. Could you please send me the link?

No, but I wound up subclassing from AdvancedDatagridGroupItemRenderer because the AdvancedDataGridItemRenderer couldn't be made to support alpha in the background but not the text. I suspect anyone wanting aplha transparency might have the same problem with the renderers on your site. Thanks; Amy

I actually didn't provide any examples, just talked about the general
principles, unless you're talking about the posts that I linked to
that didn't quite do what I wanted.
The styleFunction will do whatever you tell it to, so you can very
easily use that to style the columns based on the dataField that is a
property of the object you get in the second parameter.
So you could use something like this:
private function styleMyRenderers(data:Object,
col:AdvancedDataGridColumn){
if (data[col.dataField]=='foo'){
return {backgroundColor:0xFF};//red
}
return {backgroundColor:0x00FF00};//green
}

[flexcoders] Re: AdvancedDataGrid ItemRenderer
Tracy,
Is it because creationComplete only happens once per visible row and the
renderer is recycled on dg scroll, change, etc?
What I desperately want to learn is how to know when to override a
super's function - in this case updateDisplayList(). How would you know
to do that verses invalidateList() or invalidateDisplayList()??
Is this learned by experience (such as how I am right now), or does one
look at this code and intuitively know to override updateDisplayList?
Does it become more apparent when you start disecting inherited classes?
How is this learned?
BTW, your input helped me arrive at a very elegant solution with native
mxml - AdvancedDataGridRendererProvider:
The depth is the key - where 1 would be the Group node and 2 would be
the first indentation or sub-set of data under the grouping.
Even though I found a solution, I am still very interested in your
thoughts on the learning approach query above.
Thanks to all,
Jeff

Re: [flexcoders] Re: AdvancedDataGrid & ItemRenderer
You can find out what row they are dragging over using the information
in the DragEvent... here is a snippet that may help. It is modified
from my original code, but should get you most of the way home :) If
there is an easier way to find the item i'd sure like to know...
public function handleDragOver(event:DragEvent):void
{
var dropTargetItem:Object = null;
var
dropTarget:AdvancedDataGrid=AdvancedDataGrid(event.currentTarget);
var dropIndex:int = dropTarget.calculateDropIndex(event);
// Get drop target.
var view:ICollectionView =
ICollectionView(loadOutsGrid.dataProvider);
if(dropIndex < view.length)
{
var cursor:IViewCursor = view.createCursor();
var x:int = 0;
while(cursor.afterLast == false && x < dropIndex)
{
cursor.moveNext();
x++;
}
if(cursor.afterLast == false)
{
dropTargetItem = cursor.current;
}
}
}
