Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ColumnDisplayIndexChanged 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 DataGridView named DataGridView1. Then ensure that the event handler is associated with the ColumnDisplayIndexChanged event.

private void DataGridView1_ColumnDisplayIndexChanged(Object sender, DataGridViewColumnEventArgs e) {

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

Private Sub DataGridView1_ColumnDisplayIndexChanged(sender as Object, e as DataGridViewColumnEventArgs) _ 
     Handles DataGridView1.ColumnDisplayIndexChanged

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

End Sub
