update header on expand/collapse

[Flop]

Hello everyone,

I need to use a RadPanelBar in telerik in a way that when it is collapsed it must show a 2-3 details of a person. And when expanded, it shows complete details in its panelbaritem. I am using ItemClick event to read the expand/collapse state and update the header text. But after i implement this event, on every click (to expand/collapse), the whole page flickers. I tried couple of options, but could not avoid it.

Can someone please help? or suggest another control option option?

thanks

Hi,

One suggestion is you can try to use RadAjaxManager.
ASPX:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
   <AjaxSettings>
       <telerik:AjaxSetting AjaxControlID="RadPanelBar1">
          <UpdatedControls>
             <telerik:AjaxUpdatedControl ControlID="RadPanelBar1" />
          </UpdatedControls>
       </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadPanelBar ID="RadPanelBar1" runat="server" >
   <Items>
        ... ... ...
   </Items>
</telerik:RadPanelBar>

Thanks,
Shinu.
