How do I create a collapsed Treeview on page load

Hi, I’m working through ‘Build Your Own ASP 2.0 Website’ I’m using the Treeview example in the ‘Advanced Controls’ section of the book. I can get the Treeview to work without a problem, however, by default the Treeview displays in Expanded view when the page loads. I want the TreeView to be collapsed at page load and only show the RootNode with the Plus sign next ti it. How do I do it?

Thanks

Kevin.

set the ExpandDepth to the number of levels you want expanded initially.

Thanks, it seems so obvious now
