The new Browser Link feature in VS 2013 is causing an error when DetailTable of Hierarchy RadGrid is expanded.

[Telerik Admin]

  We have discovered an issue when expanding RadGrid DetailTable in case the Browser Link of VS 2013 is enabled. The issue is actually a generic internal problem in the VS feature and affects the RadGrid control with the following error:

“JavaScript runtime error: Syntax error, unrecognized expression: unsupported pseudo: 0_0”

  The issue is known bug in jQuery which is internally used in the Browser Link functionality. When selecting elements which contains ":" in its id, jQuery does not return element. The reason for the problem is that jQuery has some predefined pseudo-selectors and “:00” for example is not a valid selector.

  The Browser Link script tries to find our detail tables elements by its id (the detail table id contains ":"), jQuery does not return element and the Browser Link scripts throws an error that the character sequence is not recognized.

  As this issue is still not fixed in the latest version of jQuery the only workaround for now is to disable the Browser Link feature in VS 2013.

Thanks for this info. When this bug is fixed in a forthcoming jquery version, could someone post here to help others who get the error.  Also to save time in finding how to disable the browser link, you don't need to go looking through all the VS config settings. In your VS2013 IDE, locate the down-arrow selector just to the right of the refresh icon, located between the browser selector and the Debug/Release drop-down list. Click the down-arrow and un-select the option: "Enable Browser Link". MSDN also notes two other ways to achieve this setting change via code, including:

1. Set appSetting “vs:EnableBrowserLink” to “false ““. This will  disable Browser Link.

2. Set debug= false in web.config file.

Hope this saves someone some time.

so this issue caused me many hours and much pain. Dealing with an old application that uses an old telerik library. other programmer upgrade the project to VS 2013 a month ago, and started seeing the script error earlier this week but had no idea why. fortunately I Googled the right thing finally and found this post. turning off the "Enable browser link" and now is working. Just wish I could get my lost hours back...

<add key ="vs:EnableBrowserLink" value="false"/>
 Thanks a lot. It worked.

This is an issue in VS2015 also. I just installed the WebEssentials and it started erroring on my RadWindows popups.

Unhandled exception at line 37, column 59140 in http://localhost:64250/5899e8865f1844aba876e40dbab18311/browserLink

 I tried turning it off via Tools/Options, but that not work. still errored. Adding the key did turn it off:

<add key ="vs:EnableBrowserLink" value="false"/>

 

But this is 2 years later, wondering why it's still an issue.

Hello Nannette,

Note that the mentioned problem is actually a bug in JQuery used in the BrowserLink feature. As the JQuery used in the feature for VS 2015 still behaves in this way you should disabled the BrowserLink for avoiding this issue.
