title: C# Draw when window is loaded
body: <p>I want to draw some ellipses when the window is <code>loaded</code> without clicking anything, how can I do it?
  My code is the following : </p>
  
  <pre><code>        int kerX = random.Next(10,281);
          int kerY = random.Next(10,281);
          mrPainter.FillEllipse(Brushes.Black, kerX + 10, kerY + 10, 20, 20);
          mrPainter.FillEllipse(blue,65,65,20,20);
          mrPainter.FillEllipse(red, 205, 65, 20, 20);
          mrPainter.FillEllipse(yellow, 135, 215, 20, 20);
  </code></pre>
