Hi guys,

I'm having a problem with RadPanelBar. It is refreshing the whole page when I'm using it in SharePoint.

I did a sample test application without using SharePoint and it is working properly (not refreshing the whole page).

Below is the sample I create: (Note that this sample is the asp.net, not the SharePoint code as it will be the same).
Kindly highlight or specify what I did wrong or what I need to do in able to make it work on SharePoint.

Please be kind as I am not a frequent forum poster. Thanks in advance for the help/support.
