Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ListView.ColumnWidthChanged 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 ListView named ListView1. Then ensure that the event handler is associated with the ListView.ColumnWidthChanged event.

private void ListView1_ColumnWidthChanged(Object sender, ColumnWidthChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ColumnWidthChanged Event" );
}

Private Sub ListView1_ColumnWidthChanged(sender as Object, e as ColumnWidthChangedEventArgs) _ 
     Handles ListView1.ColumnWidthChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"ColumnWidthChanged Event")

End Sub
