title: Disable the drop down menu of a WPF ComboBox
body: <p>I have a ComboBox as specified below:</p>
  
  <pre><code>&lt;ComboBox Height="31" Margin="7,7,0,0" Name="callerID" IsEditable="True"  Background="LightBlue" KeyDown="callerIDbar_KeyDown" Foreground="White" FontSize="17"  FontWeight="Bold" HorizontalContentAlignment="Center" VerticalAlignment="Top" Grid.Row="0" Grid.Column="0"  /&gt;
  </code></pre>
  
  <p><code>storedCalls</code> is a collection of phone numbers that will be populated to the <code>ComboBox.Items</code>:</p>
  
  <pre><code>foreach (string call in storedCalls)
  {
     if (call != "Enter a number to dial")
        callerID.Items.Add(call);
  }
  </code></pre>
  
  <p>All this works fine.  I populate the <code>Items</code> primary because I like the autocomplete that is driven by the values in the <code>ComboBox</code>'s <code>Items</code> collections.  Is there a way the XAML to disable the drop down error, and disable the drop down menu?  I.e. make a simple auto complete textbox like control?</p>
  
  <p>I have seen full on <code>TextBox</code> controls that include a bunch of code-behind and complicated markup, and this is not what I am looking to do.  I just need to disable the ability of the drop down menu from showing.</p>
