I'm using the Telerik.Web.UI dll version v2011.2.712.35 and have a RadPanelBar that has 5 RadPanelItems.

3 of these items have an items collection in them which will be used to nvaigate around my site.
The RadPanelBar has the OnItemClicked handler configured so that the RadPanelItems can be acted upon once clicked.

The other 2 will be used as login and account detail panels. Only one will be visible depending on the state of the user (logged in or not).

The "Logged In" panel has an Items collection and makes use of the OnItemsClicked even handler mentioned above for its items.

The "Not Logged In" panel has a ContentTemplate configured in such a way as to show a small login form, consisting of 2 RadTextBoxes and a RadButton.

Now, heres the problem.

If the user is not logged in, the panel with the ContentTemplate is visible, and if the user then clicks anywhere on that panels header to expand it - other than on the arrow - the then panel doesnt expand. If the user clicks the arrow icon on the panel then it does expand.
But if the user clicks on any of the other visible RadPanelItems headerbars they do expand regardless of where on the headeer they click.

It seems that if you use the OnItemClicked handler to handle events in your RadPanelBar, and any of the RadPanelItems uses a ContentTemplate, then the expand/collapse features misbehave unless you specifically click the icon in the header.

Has anyone else experienced this, or does anyone know how to fix it?

Quick update...

Have also noticed that when the arrow is used to expand the panel with the ContentTemplate in, clicking the arrow to collapse it won't work, but clicking anywhere else on the header will?

Given that my RadPanelBar has theExpandMode property is set to SingleExpandedItem and AllowCollapseAllItems is set to false, surely I shouldn't be allowed to collapse this panel at all?

Very odd...

Hi Karl,

It looks like the scenario that you describe is very customized one and the information that you provide in not sufficient to reproduce the issue that you encounter. Also since there could be many reasons causing this issue my suggestion would be to open a support ticket and send us a simplified runnable project (containing only the very necessary controls that are needed) where we could inspect the issue and determine the proper behavior of the control in the context of your scenario.

It really isn't that custom to be honest, infact I would go so far as to say this would be fairly standard behaviour.

I will open a ticket and upload my test project so you can see for yourself...

If you open up firefox\firebug in the Console tab...there are no script errors?

Hi Steve, 

No script errors, but I do have 9 WebResource.axd warnings along with 2 of my own css warnings for "top" and "left".

I have a ticket open with Telerik now. Hopefully I'll hear something soon.

Hi Karl and Steve,

As I wrote in the ticket that I sent earlier to Karl the behavior that you experience is a bug of the RadPanelBar control that I already logged in our internal system so it can be fixed.

I just ran into this one myself and have noticed that I am never even getting into my ItemClick method.  Any ideas when the will be fixed?

Hello Shonda,

I addressed the issue to our development team, however I can not give any time frame when the bug will be fixed. They are currently doing their best, so please, wait until the beta release of the controls and check if it has been resolved.   

Kind regards,
Kate

Shonda, something you might want to look at in the time being is this...
