In my solution I have three projects: Console application, class library, and a website project. The Show All Files button is visible on the console and class library proje
If you are in a WebSite project all files are shown by default. If there are some missing (added during debugging etc), just hit the refresh button on the top of the solution explorer and they should appear.
Click on folder which must contain target file and Solution explorer properties will be changed. There you can find Refresh button and Show all files button.

Improved Solution Explorer in Visual Studio 2012 to Improve Productivity
In Solution Explorer, click on a project, and then the 'Show All Files' button will appear.
None of the above answers worked for me. If this is the case for you try right-clicking on any file in your project, then choosing "Show all files". The "Show all files" icon should now appear on this and all subsequent Solution Explorer windows.
YMMV, be kind. :-)
I just got the same problem "Solution Explorer toolbar missing" eg. "Show all files". Here's what I did:
try to open any file use ctrl+alt+a . once a file will open "show all" button will appear automatically.
