The new display position of the ColumnHeader.
Examples
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" );
}
Private Sub ListView1_ColumnReordered(sender as Object, e as ColumnReorderedEventArgs) _
Handles ListView1.ColumnReordered
Dim messageBoxVB as New System.Text.StringBuilder()
messageBoxVB.AppendFormat("{0} = {1}", "OldDisplayIndex", e.OldDisplayIndex)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "NewDisplayIndex", e.NewDisplayIndex)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "Header", e.Header)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "Cancel", e.Cancel)
messageBoxVB.AppendLine()
MessageBox.Show(messageBoxVB.ToString(),"ColumnReordered Event")
End Sub
Remarks
The ColumnReordered event can be canceled by setting the Cancel property to true. However, if the event is cancelled, the NewDisplayIndex will not change to the OldDisplayIndex value.
