title: Call a button on a C# form through usercontrol
body: <p>I've created a user control with some buttons. When you click a button in the UserControl the BackColor of the button changes:</p>
  
  <pre><code> private void button1(object sender, EventArgs e)
      {
          Control ctrl = ((Control)sender);
          switch (ctrl.BackColor.Name)
          {
              case "Crimson": ctrl.BackColor = Color.Blue; break;
              case "Green": ctrl.BackColor = Color.Orange; break;
              case "Orange": ctrl.BackColor = Color.Crimson; break;
              case "Blue": ctrl.BackColor = Color.Green; break;
              default: ctrl.BackColor = Color.Crimson; break;
          }
      }
  </code></pre>
  
  <p>on my form is another button which is enabled = false; 
  so when the color in the UserControl changes I want the button on my form enabled=true;</p>
