how do I add & remove data in a styled listbox (c# WPF)

Question

Hi,
I have tried severalexamples of styled listboxes, but cannot find any examples of how to interact with the listbox as if it was a standard control.

I can get a styled listbox to look nice on a c# window, but cannot find how to  attach it to data, or how to select and use items within it.

The only way I can see items are those added manually in design time.

 

Please could someone point me in the right direction to accomplish this, or to suggest a sample application using a styled listbox and styled listitems ?

 

Many Thanks for any help.
