Populate Treeview using Javascript

[LotusShiv]

I have an ASP.Net 2.0 application (VS.Net 2008/C#). I want to populate the Treeview on my page using javascript. So far I have heard not so positive views about populating using javascript. Still I want to give it a shot. Any help is greatly appreciated.

To add to above question, I have a text field on the page to the right side of the ASP.Net Treeview which is what that needs to be used as input to the Populate function for the OnTreeNodePopulate event. Actually, when I first enter the input and click on a search button without posting the entire page, I want to be able to populate the Treeview, hence I am looking to do client-side treeview population. That way, besides avoiding posting the whole page, I can avoid the flicker as well.
Any help is appreciated.
