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 BackgroundImageChanged 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 BackgroundImageChanged event.

private void ToolStripDropDown1_BackgroundImageChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the ToolStripDropDown.BackgroundImageChanged event.");
