title: "An inline collection of ComboBoxItem" in a DataGridComboBoxColumn
body: <p><a href="https://msdn.microsoft.com/en-us/library/system.windows.controls.datagridcomboboxcolumn(v=vs.110).aspx#Anchor_7" rel="nofollow">MSDN</a> says:</p>
  
  <blockquote>
    <p>To populate the drop-down list, first set the ItemsSource property for
    the ComboBox by using one of the following options: </p>
    
    <ul>
    <li>A static resource. For more information, see StaticResource Markup Extension. </li>
    <li>An x:Static code entity. For more information, see x:Static Markup Extension. </li>
    <li>An inline collection of ComboBoxItem types.</li>
    </ul>
  </blockquote>
  
  <p>With "<strong>An inline collection of ComboBoxItem types</strong>" I thought about something like this:</p>
  
  <pre><code>&lt;DataGrid&gt;
    &lt;DataGrid.Columns&gt;
      &lt;DataGridComboBoxColumn&gt;
        &lt;ComboBoxItem Content="None" Tag="0" /&gt;
        &lt;ComboBoxItem Content="Few" Tag="1" /&gt;
        &lt;ComboBoxItem Content="Some" Tag="2" /&gt;
        &lt;ComboBoxItem Content="Enough" Tag="3" /&gt;
        &lt;ComboBoxItem Content="Lots" Tag="4" /&gt;
        &lt;ComboBoxItem Content="Too much" Tag="5" /&gt;
      &lt;/DataGridComboBoxColumn&gt;
   &lt;/DataGrid.Columns&gt;
  &lt;/DataGrid&gt;
  </code></pre>
  
  <p>But it doesn't works. I know about another methods to populate the DataGridComboBoxColumn, but I'm curious about that, this because I find nothing about that in my research... What means "inline collection of ComboBoxItem types" then?</p>
