title: WPF grouping for checkboxes
body: <p></p>
  
  <pre><code>    &lt;CheckBox Content="1" Margin="43,73,430,227" /&gt;
      &lt;CheckBox  Content="2" Margin="123,73,359,227"/&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p>Above are my checkboxe. I need to group them. I f check 1 then 2 should be unchecked and vice versa. This should be done in xaml.  Is there any property settings or xaml code to apply my requirement other than adding c# code.</p>
