title: Binding child element property to parent element
body: <p>I have a Button in which an image is embedded in it.Now what I want is to bind the tag property of the button to Source property of the image. </p>
  
  <pre><code>&lt;Button Name="Jobs" Tag={Binding ???} Click="button_click"&gt;
    &lt;Button.Content&gt;
      &lt;Image Source="{StaticResource nsds}"/&gt;
     &lt;Button.Content&gt;
  &lt;/Button&gt;
  </code></pre>
  
  <p>I want it to be general since every button that will be created will have this Image content and the button creation will be done dynamically.
  Binding with Image Name will defeat the purpose<code>Tag={Binding ElementName=Img, Path=Source}</code> as i have to use the source of the image to recreate the image elsewhere.</p>
