Editing aspx/ascx files randomly disabled in Visual Studio 2010?

Question

I\'ll be debugging a site in Visual Studio 2010 and editing an *.aspx or *.ascx file, and without warning, it will lock up so that I can\'t edit it

Answer 1

Had the same problem with VS2010. R-click on the ASPX file and select the XML EDITOR -- then editing is enabled.
