EDIT: Basically what happens when I hit enter is that I get the File Save As dialog, and when I save the file and open it, the contents of the file has the response string.
If you are using any of the
Ajax.* helpers (such as
Ajax.ActionLink) you need to remove all
Microsoft*.js scripts and replace them with:
jquery.unobtrusive-ajax.js, like this:
The reason is that staring from ASP.NET MVC 3 Microsoft realized that reinventing the wheel is never a good thing and deprecated their MsAjax script libraries in favor to the far more advanced and better jQuery library. So those scripts are no longer used (they are just provided for backwards compatibility). ASP.NET MVC 3
Ajax.* helpers use HTML5 data-* attributes which are unobtrusively AJAXified with jQuery.
Also you should ensure that unobtrusive AJAX is enabled in your web.config:
If you still want backwards compatibility or something you could set the
Microsoft*.js libraries (absolutely not recommended).
