title: WPF SelectionChanged to same value
body: <p>I am using SelectionChanged in ComboBox item, but when I select the same item again the SelectionChanged function does not fire and I need it to do so. How can I tell it to fire no mater witch selection I do.</p>
  
  <pre><code>private void ComboBox_SelectionChanged4(object sender, SelectionChangedEventArgs e)
      {
  
        //do some stuff
  
      }
  </code></pre>
  
  <p>XAML:</p>
  
  <pre><code>&lt;ComboBox   Height="30" Name="Combo4" Style="{StaticResource CategoryComboBox}"   SelectionChanged="ComboBox_SelectionChanged4" Grid.ColumnSpan="2"  Grid.Column="0"&gt;
              &lt;ComboBoxItem Content="ComboBox Item 1 (Example)" /&gt;
              &lt;ComboBoxItem Content="ComboBox Item 2 (Example)" /&gt;
              &lt;ComboBoxItem Content="ComboBox Item 3 (Example)" /&gt;
              &lt;ComboBoxItem Content="ComboBox Item 4 (Example)" /&gt;
          &lt;/ComboBox&gt;
  </code></pre>
  
  <p>Adding items:</p>
  
  <pre><code>for (int i = 0; i &lt; Pr4.Count(); i++)
          {
              ComboBoxItem item = new ComboBoxItem();
              item.Content = Pr4[i];
              Combo4.Items.Add(item);
  
          }
  </code></pre>
