Databinding Comboboxes in XAML   

I'm databinding to a XElement (from a XML file) in XAML... All of my 
TextBoxes are a breeze, it's just a simple Text="{Binding 
Path=Element[Event].Element[Name].Value..., but I don't understand how I 
would databind to a ComboBox. How do I get the the ComboBox to automatically 
select the item whose text matches the Value from my Binding Path?

Any help with this would be greatly appreciated :)
