I am using a treeview control. I am buliding the tree dynamically. sometimes the tree becomes larger and the down scroll bar is need to see the entire tree. user can select a node from the tree. if one node is selected ,i change the color of the node from server side.
my problem is that if a user selected a node which is bottom in the tree(means, the user used the down scrollbar to see that node), after postback it shows the top of the tree.to see the selected node the user need to use the down scroll bar.
I need to show the selected node after postback. How can I do this?
Why does microsoft make objects in .NET with incomplete behavioural methods, then expect everyone to use a client side "language" to help complete the methods? I don't wanna have to use Javascript to keep focus on my leaf node in my TreeView after clicking it. I want a server side answer to my question, but if that's impossible I guess I can run ANOTHER javascript bandaid to do this, since I guess Microsoft doesn't have a solution. Oh and By the Way if your going to post an answer please remember I'm using WEBFORMS not WINFORMS. God help people who try to run my app (or any .net app) and don't have Javascript enabled on thier browsers. Does Microsoft own Javascript? Maybe since they rely so heavily on help from the client side to achieve behaviours, they ought to think about acquiring it.

I have a treeview which will be generated dynamically which need to be displayed on left side and when user clicks on a node it need to open a page on the right side of the same page. and each node has different aspx page. so whenever user selects a node the page details should be displayed on the right side .we can use an iframe on the page which will display the different pages clicked on the node.Is there any alternative i can use to display different pages based on the user selection on the right side without using iframe.
The idea here is to bind the move_node to a function that will hit the handler and update the database as to where I moved the object. I've been able to create the bind to do that. The problem, however, is that I can't seem to obtain the ID. I'm setting it in the attributes in the population of the JSON object, but when I do a watch on the NODE and REF objects via console.log, the id field is empty.

I need to retrieve a specific node from the TreeView in order to dynamically set it's NavigateUrl property. I've tried using the code below:
TreeNode homeLink = TreeView1.FindNode("Home");
However this returns System.NullReferenceException error.My guess is that I'm using a wrong valuePath in the FindNode("Home"); function. I assume that valuePath refers to the "title" property of the node in the SiteMap?ere is an extract from the sitemap:
