Simulate Treeview Root node click

Hi Experts,

I've found some good posts in EE on capturing some of the events but what i need to do is simulate the click on the root node of my treeview in javascript on the client. I'm hoping this is going to be simple and quick ! I've had a look around the treeview in firebug but can't see anything obvious, not to this beginner anyway ;-)

thanks

if root node has id assigned, you can get object handle by inquiry

 document.getElementById()

Once you have object, trigger click call


e.g

<html>
<head>
<script type="text/javascript">
function clickRoot()
  {
  document.getElementById('root').click()
  }
function alertMsg()
  {
  alert("Root  was clicked!")
  }
</script>
</head>
<body onload="clickRoot()">
<ul id="root" onclick="alertMsg();">Root

Hi pravinasar,

Apologies for delay, yes i am using the <asp:treeview> and i've been trying to code a .click() function in javascript to replicate. However it appears that there is no .click() method on an element once i've got hold of it e.g. ele = doc.getelementbyid('rootnoteid'); there is no method of .click() well not in my flavour.

What i have been ablt to ascertain is that i can replicate the click actions by coding...


__doPostBack('TreeView1','valuefromrootnode');
