I was not having a problem with the treeview prior to moving it inside a panel (which is controlled by the ajax collapsiblepanelextender control)
The treeview is set to default fully expanded. The treeview is bound to a sitemapdatasource.
When the page loads, there is some "flashing/blinking", in the middle of which I can breifly see all the items in my menu/treeview, but when the "flashing" stops and the page is fully loaded, the area where the treeview is on the page is too small to show the entire treeview/menu. Basically, the height of the treeview control gets changed to a value that is way too small to display my entire treeview/menu. The net effect is that when I expand/contract the treeview, items that are lower in the list are "cut off" the bottom.

Any ideas?
