title: Get Selected Radio Button in a Group (WPF)
body: <p>I have a <code>ItemsControl</code> in my program that contains a list of radio buttons.</p>
  
  <pre><code>&lt;ItemsControl ItemsSource="{Binding Insertions}"&gt;
          &lt;ItemsControl.ItemTemplate&gt;
              &lt;DataTemplate&gt;
                  &lt;Grid&gt;
                      &lt;RadioButton GroupName="Insertions"/&gt;
                  &lt;/Grid&gt;
              &lt;/DataTemplate&gt;
          &lt;/ItemsControl.ItemTemplate&gt;
      &lt;/ItemsControl&gt;
  </code></pre>
  
  <p>How do I find the selected radio button in the <strong>group</strong> <code>Insertions</code> in a MVVM manner? </p>
  
  <p>Most of the examples I have found on the internet involve setting individual boolean properties that you bind the <code>IsChecked</code> property to with the help of a converter.</p>
  
  <p>Is there an equivalent of the <code>ListBox</code> <code>SelectedItem</code> that I can bind to?</p>
