How to: Handle User Input Events in Windows Forms Controls

This example demonstrates how to handle most keyboard, mouse, focus, and validation events that can occur in a Windows Forms control. The text box named TextBoxInput receives the events when it has focus, and information about each event is written in the text box named TextBoxOutput in the order in which the events are raised. The application also includes a set of check boxes that can be used to filter which events to report.
