In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

You can create an event handler for this event to determine when the selected index in the ComboBox has been changed. This can be useful when you need to display information in other controls based on the current selection in the ComboBox. You can use the event handler for this event to load the information in the other controls.

For more information about handling events, see Consuming Events.

The following code example demonstrates how to initialize a ComboBox control by setting the MaxDropDownItems and DropDownStyle properties and using the FindStringExact methods to search the ComboBox. It also shows handling the SelectedIndexChanged event.
