title: No access to cooresponding .cs file in asp.net
body: <p>The <code>aspx</code> page that I need to add code to has an <code>aspx.cs</code> file which was written by a company that has this <code>aspx.cs</code> file on their system (per contract) and I cannot modify/access. 
  Example:   MyFile.aspx   and no access file MyFile.aspx.cs</p>
  
  <p>I need to use a label.text from the page in the control pages and also depending on <code>IF ELSEIF</code> statements it will call which of the different controls that it needs to execute.  </p>
  
  <p>What is a good way to do this when one does not have access to the <code>aspx.cs</code> file?</p>
  
  <p>I have spent a couple days trying to find/figure out answers to this problem and keep running into problems.</p>
