title: binding combobox to another combobox in wpf
body: <p>I have two combo boxes in wpf one of the combo boxes looks like so:</p>
  
  <pre><code>            &lt;ComboBox Height="23" HorizontalAlignment="Left" Margin="244,10,0,0" Name="comboBox2" VerticalAlignment="Top" Width="120"&gt;
                  &lt;ComboBoxItem Content="Peugeut" /&gt;
                  &lt;ComboBoxItem Content="Ford" /&gt;
                  &lt;ComboBoxItem Content="BMW" /&gt;
              &lt;/ComboBox&gt;
  </code></pre>
  
  <p>I was wondering how you bind the second combobox2 to list specifc car makes to the selected item in combobox1. </p>
  
  <p>If Peurgeut is selected then in combobox two there should be a list:</p>
  
  <pre><code>106
  206
  306 
  </code></pre>
  
  <p>or if bmw is selected then</p>
  
  <pre><code>4 series
  5 series
  </code></pre>
  
  <p>And so on</p>
