Funky formatting in databinding
This video shows how to call code in your databindings to do some funky formatting. Here I have nested a datasources inside a datalist. I show a price as crossed out if there is a sale price.

Note that you can do more than just calling Eval() in those custom dabinding statements. Also there is a warning on use of the aspx Culture tag.
Enjoy.
