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

public ColumnHeader Header { get; }

Property Value

Type: System.Windows.Forms.ColumnHeader

The ColumnHeader that is being reordered.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ListView.ColumnReordered 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.ColumnReordered event.

private void ListView1_ColumnReordered(Object sender, ColumnReorderedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "OldDisplayIndex", e.OldDisplayIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "NewDisplayIndex", e.NewDisplayIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Header", e.Header );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Cancel", e.Cancel );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ColumnReordered Event" );
}
