    I am new to .NET and have been going through some basic projects in the Visual Studio 2013 Preview version.  I have added a TreeView control to my Site.Master, and now I'm getting the error:

    'WebForm_InitCallback' is undefined

    I downloaded the JavaScript being generated from WebResource.axd, but the files are all empty.  I'm sure I missed something obvious to some of you all and would appreciate any help.

    Hi jrb

    'WebForm_InitCallback' is undefined

    I can hardly give precise troubleshoot just according to the error message above, it's recommanded to research relevant information about this error message in bing, and check whether it can give some hints for you to troubleshoot, at the same time you can also check whether the files are really existed,
