Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ContentsResized 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 RichTextBox named RichTextBox1. Then ensure that the event handler is associated with the ContentsResized event.

private void RichTextBox1_ContentsResized(Object sender, ContentsResizedEventArgs e) {

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

Private Sub RichTextBox1_ContentsResized(sender as Object, e as ContentsResizedEventArgs) _ 
     Handles RichTextBox1.ContentsResized

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

End Sub
