title: CalendarView SelectedDates are not recorded in my _DateChanged method
body: <p>...but it is when i perform the action upon a button click.</p>
  
  <p>This does not work:</p>
  
  <p>XAML:</p>
  
  <pre><code>            &lt;CalendarView CalendarViewDayItemChanging="MyCalendarView_DateChanged" x:Name="MyCalendarView" Grid.RowSpan="2" Grid.Row="1" Grid.Column="1" DisplayMode="Month" SelectionMode="Multiple" CalendarItemBackground="LightBlue" BorderBrush="Orange" BorderThickness="3" HorizontalAlignment="Center" VerticalAlignment="Center" /&gt;
  </code></pre>
  
  <p>C#:</p>
  
  <pre><code>private void MyCalendarView_DateChanged(Object sender, object e)
      {
          SelectedDate.Text = "The selected date(s):" + "\n";
          for (int i = 0; i &lt;= MyCalendarView.SelectedDates.Count - 1; i++)
          {
              SelectedDate.Text += MyCalendarView.SelectedDates[i].ToString() + "\n";
          }
  
  
      }
  </code></pre>
  
  <p>but this does work:</p>
  
  <p>XAML:</p>
  
  <pre><code>            &lt;Button x:Name="GoButton" Click="GoButton_Click" Content="Go!" Grid.Row="0" Grid.Column="1" HorizontalAlignment="Right"   VerticalAlignment="Top"/&gt;
  </code></pre>
  
  <p>C#:</p>
  
  <pre><code>private void GoButton_Click(object sender, RoutedEventArgs e)
      {
          SelectedDate.Text = "The selected date(s):" + "\n";
          for (int i = 0; i &lt;= MyCalendarView.SelectedDates.Count - 1; i++)
          {
              SelectedDate.Text += MyCalendarView.SelectedDates[i].ToString() + "\n";
          }
      }
  </code></pre>
  
  <p>What is wrong with first method? Is the SelectedDates not supposed to be refreshed automatically?</p>
  
  <p>I would prefer to avoid using button to record the user's dates' selection.</p>
  
  <p>EDIT</p>
  
  <p>And if in first method I use <code>RoutedEventArgs</code> instead of <code>Object</code> I get error:</p>
