How do I populate a Gridview control from In memory LINQ query results of an XML response?

I am trying to figure out if I am even using the right control. (Gridview)

The Linq Query works fine, but I cannot get the Gridview1 control to populate or even show.  It doesn't even error out when debugging. I can step right through the code as if everything is perfect but no data results on the web page.

I have tried it by passing the results from a Dim'd query and also directly as shown in the snippet below. Both ways  bind as far as I can tell.
Any help would be appreciated.
