Empty text template for WPF ComboBox?

Question

How would I apply "an empty text" template for WPF ComboBox ?

<ComboBox 
          ItemsSource="{Binding Messages}"
          DisplayMemberPath="CroppedMessage"
          Name="Messages"
          Width="150" Margin="0,4,4,4">
</ComboBox>

I use the above code to display a ComboBox with a few messages. Now, when the application starts there's no item chosen by default, and if so, I want to display a custom text on the ComboBox . I think I would need some kind of template with a trigger?

Try this...

<ComboBox ItemsSource="{Binding Messages}"
          DisplayMemberPath="CroppedMessage"
          Name="Messages"
          Width="150"
          Margin="0,4,4,4"
          IsEditable="True"
          Text="select" />
