Examples

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

private void RichTextBox1_VScroll(Object sender, EventArgs e) {

   MessageBox.Show("You are in the RichTextBox.VScroll event.");
}

Private Sub RichTextBox1_VScroll(sender as Object, e as EventArgs) _ 
     Handles RichTextBox1.VScroll

   MessageBox.Show("You are in the RichTextBox.VScroll event.")

End Sub
