Access DataGrid object from within Item renderer
I have defined an item renderer as the following:
<rendererProviders>
<mx:AdvancedDataGridRendererProvider
renderer="ItemNameCellField"
column="{nameColumn}"/>
</rendererProviders>
How can I access datagrid from ItemNameCellField class?
Thanks

That sounds like your renderer isn’t implementing IDropInListItemRenderer.
Doing so may help solve your problem.

Re: Access DataGrid object from within Item renderer

What could work id this:
owner.parentList. At run time it points to DataGrid. But the compiler is
not compiling it. The error:
-Access of possibly undefined property parentList through a reference with
static type DisplayObjectContainer.
Object(owner).parentList will go thru compiling but the run time will
produce the error:
Error #1069: Property parentList not found on
mx.controls.listClasses.AdvancedListBaseContentHolder and there is no
default value.
How come it's not found if I can see that parentList is the main DataGrid?
Thanks

this.owner gives me mx.controls.listClasses.AdvancedListBaseContentHolder,
outerDocument does not work.
this.owner.owner.owner will give me DataGrid. Is there any other way
getting there?
Thanks

Depends. It could be outerDocument, owner, or walking the parent chain.
