title: How can i change background of programmatically added button in C# Xamarin?
body: <p>I tried to make this, that way: btn.Background(Android.Graphics.Color holo_blue_dark); but it doesn't work, here is my code of adding this button (it's working fine except this background). Can you tell how to set other properties like height, margin etc.?</p>
  
  <pre><code>Button btn = new Button(this);
  i++;
  title = title.Trim(new Char[] { '"', '&lt;', '&gt;' });
  btn.Text = title;
  btn.Id = i;
  layout.AddView(btn);
  </code></pre>
