title: Change label in masterpage in just one content page
body: <p>How do I define a label in a masterpage from inside one control page, withouth losing it when I navigate to another control page? I know that I can use this code and it works:</p>
  
  <pre><code>        (Master.FindControl("myControl") as Label).Text = "someNewContent";
  </code></pre>
  
  <p>But I have to define this on every page to keep the same content in the label. Is there a easier/shorter way to define this piece of code only one time in the whole program? Thanks in advance.</p>
