title: How to bind Xamarin.Forms Entry to a Non String Type such as Decimal
body: <p>I have and Entry created and I am trying to bind it to a Decimal property like such: </p>
  
  <pre class="lang-cs prettyprint-override"><code>var downPayment = new Entry () {
      HorizontalOptions = LayoutOptions.FillAndExpand,
      Placeholder = "Down Payment",
      Keyboard = Keyboard.Numeric
  };
  downPayment.SetBinding (Entry.TextProperty, "DownPayment");
  </code></pre>
  
  <p>I am getting the following error when I try to type into the Entry on the simulator.</p>
  
  <blockquote>
    <p>Object type System.String cannot be converted to target type: System.Decimal</p>
  </blockquote>
