We'll use the TutList application, to demonstrate this phenomenon. The implementation of such a feature can cross many disciplines and many portions of a code base. The “read” flag is a great example of a conceptually simply feature that may have far-reaching consequences to the application as a whole. This tutorial is going to show you, by way of implementation in an existing application, how one might go about incorporating a read flag feature into a ListView control. One common feature of "reader"-type applications is keeping track of items that have been read, or previously viewed.
