title: Hide a usercontrol in a usercontrol from another form
body: <p>I have a user control named <code>Meeting</code> which is inside a user control <code>P2</code> inside <code>Form2</code>. From <code>Form1</code> I call a function named <code>Update</code> in <code>P2</code> :</p>
  
  <pre><code>public void Update1()
  {
      meeting1.Visible = false;
  }
  </code></pre>
  
  <p>So from Form 1 I use :</p>
  
  <pre><code>    P2 p = new P2();
      p.Update();
  </code></pre>
  
  <p>And it does nothing. If I use the function from <code>P2</code> directly it works but it doesn't work if I try to use it from Form1. If i add a <code>MessageBox</code> inside the function, the MessageBox works but codes regarding <code>meeting</code> doesn't.</p>
