Combo Box in Windows CE Environment

[Steve]

Win CE, C# Forms app

I am trying to write a C# app for win ce. In my normal windows app I create
a ListItem object with a display value and a key value and just add it to the
Items of the combo:

ListItem item = new ListItem("Steve", 012);

combo.Items.Add(item);

Then when the user selects Steve, I can retrieve the unique id for steve, in
this example 012.

How do I do this in the mobile world?? I cant see the ListItem class for a
start!

Cheers

Steve
