title: User Control showing in panel issue
body: <p>I have a mainForm that has 3 panels.  Panel3 is the one where I want my user control's to show.  On my main form if I have a button (on left menu) I use this code and it works great:</p>
  
  <pre><code>panel3.Controls.Clear();
  UserControl2 userControl2 = new UserControl2();
  userControl2.Dock = DockStyle.Fill;
  panel3.Controls.Add(userControl2);
  </code></pre>
  
  <p>My issue is when I have a button on that User Control 2 and I want that button click to bring up a UC called Employee List.  It can't find panel 3.  So my question is how can I tie Employee list to open up in Main Form Panel 3 or is there a better way to do that?</p>
  
  <p>UPDATE: I did this and it works.. but it creates another main form with my employee list UC open now in panel3.. how can I just have it open and not create another main form?</p>
  
  <pre><code>mainForm mf = new mainForm();
  mf.panel3.Controls.Clear();
  employeeList empList = new employeeList();
  empList.Dock = DockStyle.Fill;
  mf.panel3.Controls.Add(empList);
  mf.Show();
  </code></pre>
