Hi,

I am using a RadPanelBar and within the RadPanelBar I have a radgrid, that is being populated by data OnItemClick event.

My problem is that all expansion behavior is lost once a panel bar is open it cannot be closed again, and ieve the SingleExpanededItem expandMode is lost.

Any Help?

Thanks.

Hello Ivan,

I've already replied to the support forum regarding this issue. I'm pasting my reply here:

The reason for this is that the item template is set globally and this means that it is applied to all the items - including the root items - when root items have templates they cannot be expanded and collapsed. You should set the template to the subitems only, this can be done in the aspx if your items are also defined there or dynamically as demonstrated here.
