You could try moving the trigger to the ComboBox level.

<ControlTemplate TargetType="{x:Type ComboBox}">
   <Grid>
      <Border Background="Green" x:Name="ComboBoxBorder">
         <Grid>
            <ToggleButton ... />
            <TextBox Visibility="Hidden" x:Name="PART_EditableTextBox" ...>
         </Grid>
      </Border>
   <Grid>
   <!-- other stuff here -->
   <ControlTemplate.Triggers>
      <!-- your trigger goes HERE -->
      <Trigger SourceName="PART_EditableTextBox" Property="UIElement.IsKeyboardFocused" Value="True">
         <Setter TargetName="ComboBoxBorder" Property="Background" Value="Blue" />
      </Trigger>
   </ControlTemplate.Triggers>
</ControlTemplate>

private _host = null;

private void StartServer()
{
  _host = new ServiceHost(typeof(DataBase.DataBaseService ), new Uri("http://localhost:8000/DataBaseService"));
  _host.AddServiceEndpoint(typeof(DataBase.IDataBaseService),
    new BasicHttpBinding(), "DataBaseService");
  _host.Open();
}

private void StopServer()
{
  if (_host != null)
  {
    _host.Close();
    _host.Dispose();
  }
}

It seems like WPF may be more time-consuming to develop in with fewer 3rd party controls.
