I'm working on atlas and I'm testing some functionnality. I created a page with a treeview contained in an update panel and another update panel that shoul be updated when one selects a node but it doesn't work. Can someone help me?
Here is th source code:

There is a bug with the TreeView. If you remove ShowLines (or set it to false) it should work. When ShowLines is set to true, the controlsometimes generates invalid xhtml.

Thanks for your reply. This is the error generated when I debug:
"The EventName must be set to a valid event name on the associated control"
And it occurs because of the triggers tag.
Could someone help me to fix this problem?
