I'm trying to build a "File Manager" for allow our students to access files on a network drive at home just like they do when they're in our labs but I can't seem to get the datagrid that'll list the files to populate when a node on the DNNTree is clicked. If I bind a test datagrid in the Page_Load function it binds but the exact same code doesn't when I call it from PopulateTree. The grid appears to get the datasource and binds without any errors (rows match what the source has) but it never displays on the page. Any idea what I'm missing?

If I am understanding you correctly you are trying to populate another control during the callback of the treeview's populate on demand?  While it is true that the context of the callback is maintained, only the data relevant to the control raising the callback is sent back.  The rest of the page's html is not sent back down to the treeview. 

Am I understanding you correctly?

Yes that is what I'm trying to do. What I'm trying to do is populate a datagrid based on the node of the tree that's selected (similar to DNN's File Manager). I realize that the html isn't being regenerated (no postback) but I'm not sure what I need to do to force (I guess) a postback.

The way the filemanager works is it uses the NodeClick event to populate the grid.  This occurs during a postback only when your node has it's ClickAction set to PostBack.  I believe this is the default for the TreeNodes (didn't check).

Doh!!!! I had it set to Expand. I just changed it to Postback and it's working closer to what I need. Would I need Javascript to be able to have both the postback and expand happen on a NodeClick?
