Unhandled (JavaScript) exception in RadPanelBar

[Marja]

Hi,

This morning, we changed the target framework for our web application from ASP.NET 4.0 to 4.5. And accordingly, we also changed the project references to point at the Telerik Bin45 folder instead of the Bin40 folder..

Since then, we get the following error when running the application:

Unhandled exception at line 37, column 59140 in http://localhost:49950/1f27ba37075b4daeb798953036e5ebbd/browserLink

0x800a139e - Runtime-fout JavaScript: Syntax error, unrecognized expression: div#ctl00_RadPanelBar2>ul>li.rpItem rpFirst

We use "Visual Studio Express 2013 for Web" for development.
And we're running/testing on 'localhost' using IIS Express on a Windows 8.1 laptop.

What might be the cause of this error?

Best regards, Marja

I see in the submitted post that some characters were lost in the error message.

In fact, just before "rpFirst" in that last line there is "& # 3 2 ;" in the error message (I've put spaces between characters now to not lose them again) .
And I think that HTML-character is probably the cause of the problem?

Never mind. It turns out it had something to do with a debugging option in Visual Studio called "Browser Link". When I turned that off, the error disappeared.
