I have a RadTreeView inside a user control with a custom skin. The base behavior is to expand the nodes on a double click, but I want it to be on a single click to expand, so i followed this help item at : http://www.telerik.com/help/radcontrols/prometheus/tree_expand_onsingleclick.html but it doesnt seem like the BeforeClientClick event is firing. Here is my markup:
<%
@ Control Language="C#" AutoEventWireup="true" CodeBehind="MainMenu.ascx.cs" Inherits="website.MainMenu" %>
<%
@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<
script type="text/javascript" language="javascript">
function ClickHandler(node)
{
if(node.Nodes.length > 0)
{
node.Toggle();
}
}
</
script>
<div id="sidenav">
<div class="sidetop"></div>
<telerik:RadTreeView ID="RadTVTestMenu" runat="server" onnodedatabound="RadTVTestMenu_NodeDataBound" Skin="wired" EnableEmbeddedSkins="false" BeforeClientClick="ClickHandler">
<CollapseAnimation Type="OutQuint" Duration="100"></CollapseAnimation>
<ExpandAnimation Type="OutQuart" Duration="100"></ExpandAnimation>
</telerik:RadTreeView>
<div class="sidebottom"></div>
</
div>

Actually, this article is obsolete. It is not going to exist in the Prometheus help of Q3 SP2 release due by the end of the month. The help will be entirely updated.
With RadTreeView Prometheus you have to use the OnClientNodeClicking event, like:
function OnClientNodeClicking(sender, args)
{
var node = args.get_node();
if(node.get_nodes().get_count()>0)
node.toggle();
}
For more details please refer to the following articles:

Changes in the The RadTreeView class

Hope these help.
