Find A TreeView Node From Codebehind?

Feb 21, 2011

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:

<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode url="" title="" description="" SelectAction="Expand" roles="*">

Web Forms :: How To Highlight Selected Node In Treeview Using Javascript

Jun 30, 2010

Im using an asp.net treeview control and i managed to get code from these forums so that when i select a node no postback is done but i can access the selected node in my C# code behind pages by using javascript.

It works fine i can get the selected node by saying:

TreeNode t = TreeView1.SelectedNode;

and then displaying it to a label on an on click event of a button:

Label1.Text = t.Text;

But what i really need is to either display the node selected to a label (or textbox) or when a node is selected it needs to be highlighted so that the end user knows the option chosen is selected.

VS 2010 Populate Child Node When Parent Node Is Selected

Oct 16, 2012

I'm populating a treeview dynamically. On OnTreeNodePopulate I call a sub and populate the Parent nodes. I do not want to populate the child nodes at this time. Upto this point it works fine.

Now I would like the user to click the parent node and then populate the child node. I tried to use TreeNodeExpanded, but that is called for each parent node, so that didn't work.

Web Forms :: Expand A Particular Node On Treeview

Jun 22, 2010

What I am acheiving is a simple treeview which will have a tree structure

Simple stuff !. Here is the code

TreeNode tree1 = new TreeNode("dir1", "", "", "dir1", "");
tree.Nodes.Add(tree1);
TreeNode node = new TreeNode("xx", "xx");

I have put the code

tree.CollapseAll();
tree.FindNode("dir1").Select(); <-- falls over
tree.FindNode("dir1").Expand();
tree.FindNode("dir1/xx").Select();
tree.FindNode("dir1/xx").Expand();

but it falls over on the 2nd line with object not set

Oct 27, 2010

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.
