title: Margin of control in window from
body: <p>I create a control like this:</p>
  
  <pre><code>public class MyTextBoxControl : System.Windows.Forms.TextBox
  {
  }
  </code></pre>
  
  <p>and I drag-drop MyTextBoxControl to a window form, default margin is "3, 3, 3, 3"</p>
  
  <p>My question is "Can I change default margin when drag-drop my control to a form?"</p>
  
  <p>I want set default margin is "5, 5, 5, 5" and when I drag-drop my control to a form, margin is "5, 5, 5, 5". NOT "3, 3, 3, 3"</p>
  
  <p>Thanks.</p>
