title: Xamarin.Forms XAML - Adding an Entry to a Toolbar
body: <p>In my MasterDetail, I have a simple page:</p>
  
  <pre><code>&lt;ContentPage xmlns="..."  Title="Detail"&gt;
    &lt;ContentPage.ToolbarItems&gt;
      &lt;ToolbarItem Text="Hi" Icon="icon"&gt;&lt;Entry&gt;&lt;/Entry&gt;&lt;/ToolbarItem&gt;
    &lt;/ContentPage.ToolbarItems&gt;
  </code></pre>
  
  <p>I am trying to add an Entry, or better, a custom View into the Toolbar. How would I access the toolbar to add such a control?</p>
  
  <p>(Bascially I need a search textbox on the toolbar on every page)</p>
