  Hello,
  
  In order to add any other controls inside RadPanelBarItem, you need to use RadPanelItem template.
  
  Check out the following help article for more on this.

  Thanks,

  Hello phyu,
  
  Please take a look at this Knowledge Base article for a solution.

  Consider using RadControls for ASP.NET AJAX (built on top of the ASP.NET AJAX framework) as a replacement for the Telerik ASP.NET Classic controls, See the product support lifecycle here.
