I'm afraid that I'm not familiar with a Sys.Application.Dispose
method. Is it a method in a custom library, or do you just mean the Sys.Application.dispose()
method? If the second option, basically you don't need to call that method, as it is called automatically in the page unload phase. If called during the page load phase it could break the proper client-side operation of the controls.
Please, find attached a small application with RadPanelBar
in a page, located in an IFrame
I just prepared. Can you fill it to demonstrate the problem and send it back? Please note, that the attached archive contains the trial versions of the Telerik.Web.UI
assemblies. You can download the dev release from your ClientNet
the Telerik team
