[Babba]

Sorry for my english...

I have a treeview web control that add node after click of a node: the
page post back and add new childs node from a db... but the ALL PAGE
REFRESH and i don't like it!!
.... is possible to block the refresh of the page?

....I have to use the client version of the treeview to resolve the
problem and call a page that response xml node?


What do you suggest me?
THANK YOU!

if you block the refresh you cannot get data from the server. getting data
on the server implies a postback. if you don't like that you only option is
client scripting.
