ListBox Bound DataTemplate Shows Up Blank
-
Folks, I've been staring at this for hours and am missing something simple. Items in the first list box show up fine. However, I need to use a DataTemplate because the items in my real app are much more complex. Three items show up in the second listbox but they are all blank. Any ideas?

Ron - change this line:
<Label Content="{Binding XPath=SetNum}"/>
to
<Label Content="{Binding}"/>
That ought to do it.

Thanks Pete. That did it. Upon reflection, the binding already included XPath so it did not need to be in the data template.

:-D I know - it's always something simple like that, that keeps you hunting about for hours.
