How to put Expand all and Collapse all button for a asp.net TreeView Control ?

[vivek]

Well I have been using the new Microsoft asp.net 2.0 TreeView Control
in my application. I need to provide some kind of "Expand All" and
"Collapse All" button. This button should not post the form back to the
server but should work by Javascript only. Any suggestion is welcome.

Thanks

Try this:

TreeView_ToggleNode(ctl00_MainContent_TreeView1_Data,0,ctl00_MainContent_TreeView1n0,'-',ctl00_MainContent_TreeView1n0Nodes);
