How do I show the selected node in the TreeView?

[Flyguy]

I have a TreeView with so many nodes that it requires scroll bars. When the
user selects a node the screen is refreshed and the selected node is no
longer visible. The TreeView is opened to the selected node but the screen
is not scrolled to it. How can I get the TreeView to show the selected node
after it has been refreshed?

Hi,

As for the following question you mentioned:

==========
How can I get the TreeView to show the selected node after it has been
refreshed?
===========

do you mean you want to keep the browser at the original position(before it
postback) when you select a Node in TreeView?

If this is the case, you can try setting the
"MaintainScrollPositionOnPostback" attribute to "true" on the aspx page.
This can help make the page keep scroll to the last point before you
perform postback operations(such as select node in TreeView or click a
postback button...):

<%@ Page Language="C#" ..............
MaintainScrollPositionOnPostback="false" %>
