Panelbar script causing Warning: Unresponsive script error

[Pivetal]

Hi,

I am loading multiple controls using a RadTabstrip and RadMultipage combination. For the RadMultipage I have set RenderSelectedPageOnly flag to true, with one usercontrol on each pageview. On one of my controls I have a radpanelbar which hosts several RadPanelItem which intern host radcharts. After selecting a few different tabs (hence loading different controls) I get the following error in firefox (same for IE) Warning: Unresponsive script. When I debug the error I find myself within the javascript functions associated with RadPanelEventArgs:
_windowLoadHandler
->__callRadShow
->__repaintPanelBarItems
->get_expandedItems
->__findItemByHierarchicalIndex

I am quite surprised that I am within these functions as the panelbar is not being shown but I guess the event is still being fired!

When i take the radpanelbar out everything behaves as expected, but obviously I would like to keep it in; is there something I should be doing. Sorry I do not have an example to hand so hopefully I have provided enough information for you to go on!

Thanks
Bleddyn

Thank you for your fast reply!

I have tried the fix; it did improve the performance; but not enough!

So I will open a support ticket.
