E4x is much simpler to navigate.
If so, don't specify the "Item." part of the reference, just the name of
the property:
<mx:DataGridColumn headerText="Item ID" dataField="ItemID" />
At least that was how it is was done in 1.5.

Subject: [flexcoders] Re: Accessing child nodes from XMLDocument in a
datagrid
Hi JG,
Yes, I know my question is a little confusing. What I am really
trying to do is to get the commented code near the bottom to work.
What I mean is, when I uncomment those lines, and try to specify
those specific columns (i.e. to display Item.ItemId, Item.Title,
etc...), my datagrid becomes empty. I think it is because I am
trying to access the child nodes of the Item, such as the ItemId,
and the Title. I don't know how to do it properly. As you can see,
I've tried "Item.ItemId". I've also tried "firstChild.ItemId",
or "firstChild.firstChild", and even firstChild.nextSibling", but
all with the same result...nothing. I hope that clarifies my
problem. Thanks for the reply though!
