DisplayMemberChanged Event

ListControl.DisplayMemberChanged Event

Occurs when the DisplayMember property changes.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

'Declaration
Public Event DisplayMemberChanged As EventHandler

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 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.

Private Sub ListControl1_DisplayMemberChanged(sender as Object, e as EventArgs) _ 
     Handles ListControl1.DisplayMemberChanged

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

End Sub
