Dan,
The problem (I assume) is that the object you're getitng back isn't XML. I was
using that as an example, but when you use the "as" operator if the object
isn't that type it will always return null.
What is your data provider? Is it an array of objects? XML? It all depends on
what you're doing. Either way, it's based on a list. Getting the selected
item will give you a generic "object" that you need to cast to whichever data
type (actually, you don't have to but it's nicer) at which point you have all
of the properties accessible and you can grab the same property that the first
column is bound to.

Julian... Apparently you are wrong?
When I do it with an untyped var I get an object with an XMLList for each grid
column
var squat = dataGrid.selectedIt em;
This
var myValue:XML = dataGrid.selectedIt em as XML;
returns null for myValue
Why is it such Rocket Science to get the first value in a column?
Very frustrating for something that should be so simple.
Thanks for the help
Dan
