RichTextBox.HScroll Event

Occurs when the user clicks the horizontal scroll bar of the control.

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

public event EventHandler HScroll

For more information about handling events, see Consuming Events.

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

private void RichTextBox1_HScroll(Object sender, EventArgs e) {

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

}
