When running my ASP.NET webforms app in the Visual Studio 2012 debugger using IIS Express and a localhost URL I'm getting the following error:
JavaScript runtime error: 'WebForm_InitCallback' is undefined
however when I deploy the app and run under IIS I do not get the error. I've tried everything and can't resolve this. Any suggestions?

I encountrered the same issue, my local project started throwing JS errors (after a windows 8 reinstall) like you mentioned and failed to load WebResource files (css mostly). On IIS these errors did not occur. After A LOT of searching (internet was not really helpful) I found that adding a RadStylesheetmanager to my (master)page resolved all my issues.
<head runat="server">
<title></title>
<telerik:RadStyleSheetManager id="RadStyleSheetManager1" runat="server" />
</head>
Dont ask me why, all I know is I can make the errors appear/dissapear by resp. removing/adding this element, at this time I'm glad I finally solved this and I'll settle for a solution with no explanation.
