ASP.NET 4 Unleashed

Handling the Command Event

All three Button controls support both the Click event and the Command event. The difference between these events is that you can pass a command name and command argument to a Command event handler but not to a Click event handler.

For example, the page in Listing 2.25 contains two Button controls and a BulletedList control. When you click the first button, the items displayed by the BulletedList control are sorted in ascending order, and when you click the second button, the items displayed by the BulletedList control are sorted in descending order (see Figure 2.15).
