title: How do you call master page methods from a content page when the button is inside an update panel?
body: <p>I have a masterpage and a content page. In the content page I have a script manager and an update panel. In the update panel I want to be able to click a button which would hit a public method on the master page to show a message.  This works if I don't have an update panel on the content page but is there a way to get it to work when the button is in an update panel?</p>
  
  <p>Master Page:</p>
  
  <pre><code>public void ShowMessage(string Message) 
  {
      lblError.Text = Message; 
      lblError.Visible = True; 
  }
  </code></pre>
  
  <p>Content Page:</p>
  
  <pre><code>Master.ShowMessage("something");
  </code></pre>
