For more information about handling events, see Handling and Raising Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the KeyPress event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type ToolStripDropDown named ToolStripDropDown1. Then ensure that the event handler is associated with the KeyPress event.

private void ToolStripDropDown1_KeyPress(Object sender, KeyPressEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "KeyChar", e.KeyChar );
messageBoxCS.AppendFormat("{0} = {1}", "Handled", e.Handled );
MessageBox.Show(messageBoxCS.ToString(), "KeyPress Event" );
