RadTreeView & _expand()

[Suzi]

I use the version RadControls_Q4_2006_SP2_dev into my existing project. I would like to use RadControls_for_ASP.NET_AJAX_2008_1_619 into this project.

I read this article http://www.telerik.com/help/aspnet-ajax/tree_overviermigrating.html.

Into Client-Side Changes, th project doesn't recognize this javascript method :

- node.expand();
- node.set_expanded(true);

I don't know what to do... Do you have any idea ?

Thanks in advance,

Hello Suzi,

What do you mean by saying "the project doesn't recognize this javascript method"?

I have a javascript error :

node.expand is not a function.

node.expand();

I am using the trial version of telerik : RadControls_for_ASP.NET_AJAX_2008_1_619_trial

Hi Suzi,

Please check this online example. It demonstrates how to expand/collapse nodes.

So, The toggle method can be called only for the selectedNode ?

var treeView = $find("<%=RadTreeView1.ClientID%>")
var selectedNode = treeView.get_selectedNode();
selectedNode.toggle();
