View 3 RepliesI'm trying to get my treeview control to work where a user clicks on a parent node. The node will expand.Then, the user clicks on another parent node and that node expands while the previous parent node stays expanded.

View 6 RepliesI 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="*">

How to populate or bind TreeView from one table use SQLSERVER database in ASP.NET & C# table include
ID,Name,ParentID

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.

tree.FindNode("dir1/xx").Select();
tree.FindNode("dir1/xx").Expand();
