ListControl.DisplayMemberChanged Event

Definition

Occurs when the DisplayMember property changes.

C#
public event EventHandler DisplayMemberChanged;
C#
public event EventHandler? DisplayMemberChanged;

Event Type

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the DisplayMemberChanged 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 a type that inherits from ListControl, such as a ComboBox or ListBox. Then name the instance ListControl1 and ensure that the event handler is associated with the DisplayMemberChanged event.

C#
private void ListControl1_DisplayMemberChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the ListControl.DisplayMemberChanged event.");
}
