title: Programmatically add UITextField to UIView with MonoTouch
body: <p>I am learning to use MonoTouch. I have a screen with two buttons. When a user clicks a button, a view that I have programmatically created will appear and hide the other. I have this successfully working. In one of my views, I want to show a text box. While I believe that I have created / add the the text box correctly to my view, it is not appearing. My initialization code is shown here:</p>
  
  <pre><code>RectangleF rectangle1 = new RectangleF(0, 100, 200, 200);
  this.view1 = new UIView(rectangle1);
  this.View.Add(view1);
  
  RectangleF rectangle2 = new RectangleF(0, 0, UIScreen.MainScreen.Bounds.Width, 300);
  this.view2 = new UIView(rectangle2);
  this.view2.Hidden = true;
  this.view2.BackgroundColor = UIColor.Green;
  
  UITextField textField = new UITextField();
  textField.Bounds = new RectangleF(20, 13, 200, 31);
  view2.AddSubView(textField);
  
  this.View.Add(view2);
  </code></pre>
  
  <p>What am I doing wrong? Why isn't the textField appearing?</p>
  
  <p>Thank you!</p>
