Expanding obout.com ASP.NET TreeView from Delphi WebBrowser

[MarkR]

I have a website using this a treeview component:http://www.obout.com/t2/ex_expand_levels.aspxI need expand all nodes of the treeview.I DONT have the buttons (nor the functions) just the treeview itself. I have loaded the page and able to send JavaScript to the website, but have not been able to simulate click on the "+" signs to expand a nodes. I have got several.I would really like to see a simple example code if possible...Thanks in advance,Zsolt
