Getting errors for code in unopened .aspx pages

Question

Is there a way to check for errors in closed * .ASPX pages. For example, if you change the function name, will Visual Studio catch the error on the page and list it in the "error list" only if the page is open and checked?

I think the question may be, is there a check option opposite to the compilation option for checking errors?

(Yes, I know that the code should go into pre-compiled code pages).

How to find out about the following without starting a page through a web server or opening a page for verification in VS?

<script runat="server">
     Public Sub MyFunciton() 
         Undefined_FUNCTION()
     End Sub
 </script>
