ListControl.FormatStringChanged Event

Occurs when value of the FormatString property changes

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

'Declaration
Public Event FormatStringChanged 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 FormatStringChanged 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 FormatStringChanged event.

Private Sub ListControl1_FormatStringChanged(sender as Object, e as EventArgs) _ 
     Handles ListControl1.FormatStringChanged

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

End Sub
