Hi,

I have a treeview which gets its data from a xml datasource.

I am registering a CallBackReference on node expand (using the ICallbackEventHandler interface)

Basically my requirement is to reach to the server side without posting the page as my treeview has more than 500 nodes.

Problem: In the server side when i do a Treeview.Items.Count i get 0.

Any idea on this or else any other approach you can suggest to achieve the same functionality ?

Please refer the below link for samples files which illustrates of getting the TreeView items count value from server side using CallbackMultiplexer and without posting the page.
