title: Is it possible specify Xamarin Forms Entry Numeric Keyboard without comma or decimal point separator?
body: <p>I have to create a form in which the user must input his age. I would like to use a numeric keyboard:</p>
  
  <pre><code>    &lt;Entry
          x:Name="AgeEntry"
          VerticalOptions="FillAndExpand"
          HorizontalOptions="FillAndExpand"
          Keyboard="Numeric"
      /&gt;
  </code></pre>
  
  <p>but it shows even the decimal point character, I'd like to show only numbers...</p>
