[v2.x only]Panelbar group not expanded when a page loads

PROBLEM
When calling a page containing the panelbar, the panelbar item  with href="[this page's url]" is NOT expanded/selected (v2.x only)

REASON
The panelbar cannot know which item on which page was previously selected - in theory the user could have come to the page from anywhere - just a URL has been followed. E.g., the panelbar does not know that the user clicked on a link within a panelbar in order to come to this page. On the server it might be one single user control, but this control is included in completely independent pages (and the information is not transfered in a postback, since there is NO postback).

SOLUTION

1. The easiest step is to try the AutoUrlDetect property and see if it will do the job in your scenario (not guaranteed when you have multiple nested directories in the site).

2. Use the SelectedId, SelectedLabel or SelectedUrl properties.
For an example how to use the property, see the panelbar installation example framework, or the KB article in RadPanelBar -> How To's.
