Expand Treeview node based on bowser URL
Hi
How can i expand the node based on the page url.
I'm using the treeview in sharepoint using sitemap datasource.
want to expand the node based on the site/ sub site and in the expanded node it should be selected child node based on the pagename
Thanks
Arun
Hello Arunkumar,
There is a method set_expand() that you can use.
sample
function pageLoad() var tree = $find("<%= RadTreeview1.ClientID %>"); if (tree) var location = window.location.pathname; location = location.substring(location.lastIndexOf('/') + 1); var nodeText = location.split('.'); var currentNode = tree.findNodeByText(nodeText[0]); if (currentNode) currentNode.set_expanded(true); while using the code i got the following error
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)
sorry for the cause im very new to Telerik controls, forgive me if i did anything wrong.
Here is my code
and the xml file contains the following code

Hi Arunkumar,
To select a node use set_selected method on the client. get_parent will give you the parent node and set_expanded Expands or collapses a Node.
Sincerely yours,
Ivan Dimitrov
