View 5 RepliesI have a master page containing a tree and 3 dropdown lists. I am populating a context menu on right click of each node, and when clicked on any item of the context menu, it navigates to required pages.
My problem is after navigating to the required page, the selected values from the drop down lists and the selected node from the tree are getting cleared.
I can set the selected values for the dropdown lists by making some properties in master page.
But how do i maintain the selected node?
In my content page, i have got the valuepath of the right clicked node.
Or is there any other way than setting the properties in master page?

TreeNode node = new TreeNode("xx", "xx");
tree1.ChildNodes.Add(node);
TreeNode tree2 = new TreeNode("dir2", "", "", "dir2", "");

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();

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="*">
