Tim sets the DataContext on the DockPanel to be a binding to the items in the RSS feed.

Then the nested ListBox doesn't need to say anything except to Bind. It gets its data from its parent DataContext.

I just tested it out and it seemed to be fine. Try going directly to the URL for the WMV:

After attending the PDC, I've installed the Sept CTP bits.  I've copied your sample (above) and it doesn't work in XAMLPAD.  Am I missing something? 

Here's a couple keywords that its "upset" about:

XmlDataSource   --> changed to XmlDataProvider

Wrap  --> removed as it just won't work.

 

Then another quick question...  What code could I add to this sample to automatically get new RSS content and have the lists automatically update?  I was trying to do things declartively... I was trying to set the source of the XmlDataProvider to be bound to a TextBox.  But to no avail.  Do I need to revert to code behind?

With some effort it has been possible to figure out the changes and/or find updated demos.

However, it would be helpful if the various tech evangelists were to post updated demos that work on the PDC05 bits.

Thanks!

Erik

TextWrapping="Wrap"

And for TextContent="..." just use Text="..."
