title: Setting a button icon in C#
body: <p><img src="https://i.stack.imgur.com/q1vlQ.png" alt="enter image description here"></p>
  
  <p>Is it possible the change the Icon for btnEdit in my C# code? For example, when you click on btnEdit, the Icon will switch from "Edit" to "Cancel"?</p>
  
  <p>This app is for Windows Phone 8.1, and I want to use the icons that have already been provided.</p>
  
  <p>I have so far been able to switch the label (btnEdit.Label = "Cancel") and this works, but I can't seem to get it working for Icon.</p>
  
  <p>Any suggestions?</p>
