Hello,
In my page I have a button.
When I press this button, I want radpanelbar to expand/collapse and  make a specific item as selected, without leaving/reloading  the page.
I can find the item I want to be selected.
I'm looking for the functions to make radpanelbar expand/collapse in order to show this item as selected.
For example:
In page
http://www.telerik.com/help/aspnet-ajax/editoroverview.html
<overview> is highlighted.
with my javascript, the selection <RadAjax for ASP.NET vs RadAjax for ASP.NET AJAX> will be highlighted (thus the tree will expand by itsself) , but the page that it'll show will be still the same page (http://www.telerik.com/help/aspnet-ajax/editoroverview.html).

he code is :
<script type="text/javascript">
<!--
function MsgBox1() {
alert("beginning");
var panel1 = $find('ctl00_PlaceHolderLeftNavBar_RadPanelBar3'); // I had problem using $find (<%= RadPanelBar3 %>)
var item1 = panel1.get_items();
var itemurl = panel1.findItemByText("RadAjax for ASP.NET vs RadAjax for ASP.NET AJAX");.
// which function should I call to make itemurl as the selected and make radpanelbar redisplay (thus showing itemurl as selected);
}
 -->
</script>
<INPUT NAME="submit" TYPE=Button VALUE="Change RadPanelMenou!!" onClick="MsgBox1()">

I hope it's not very difficult to understand.
Thank you!

Hello Christos,

You could call the expand method of the Item to expand it.
