The name 'Web Control' does not exist in the current context. Error Message in Visual Studio.

I noticed these errors while building my project (Image#1), but wasn't able to fix them until I declared all of them in the Code behind file (Image #2).
It worked fine & I cleared all the errors in al the pages in Visual Studio, BUT the code wouldn't work right on the webpage (Image #3).
With this block of Web Controls commented out, I get 3782 errors as you can see below (Image #1).  When these blocks are Uncommented, that number goes down to 3755 (Image #2) and eventually clears all error messages.
Can anyone assist with this annoyance?
