Is there a simple way to use the AdvancedDataGrid with hierarchical data
from XML, while excluding all but certain node types from the navigation
hierarchy?
For example, with the following XML, I don't want the name node showing up
as a folder in the nav tree. Obviously, if name were an attribute rather
than an element this wouldn't be a problem.
<group>
<name>Group 1</name>
<group>
<name>Group 1a</name>
</group>
</group>
I didn't think GroupingCollection was appropriate, since the data is already
hierarchical and <groups> can be recursively nested.
