title: Access Master Page public method from user control/class/page
body: <p>I am to access a method on my master page. I have an error label which I want to update based on error messages I get from my site. </p>
  
  <pre><code>public string ErrorText
  {
      get { return this.infoLabel.Text; }
      set { this.infoLabel.Text = value; }
  }
  </code></pre>
  
  <p>How can I access this from my user control or classes that I set up?</p>
