hi I have a RadTreeView which I have bound to an XML string. All works good no issues. I am now trying to add a navigation URL so that when the user clicks on a node of the treeview It will open a window based on the navigation URL. How can I do this so that I can specify the URL in XML which I pass to the Tree View.

Thanks
Vinay

Hello Vinay,

There are two ways to accomplish this:

1. To insert a NavigateUrl to each node in the .xml file as described below:

<Node Value="14" Text="Unread Mail" NavigateUrl="http://www.telerik.com"/>

2. You can bind the RadTreeView to a XMLDataSource and subscribe to the OnDataBound event and add additional properties in the handler. Please take a look at this help topic for reference.

Hope this helps.

Kind regards,

Thanks.

There is one more query. When i click on the node I want to populate a Rad Grid, with values from a webservice. Is it possible to do this without doing a complete post back. and Only refreshing the Grid area ? I am new to Ajax.

Hi Vinay,

You'll need to use RadAjaxManager. Please take a look at this help topic and this demo for an example.

Feel free to ask me if you have further questions.
