Gets the scroll bar orientation that raised the Scroll event.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
You would typically use the property to determine the scroll bar orientation that raised the Scroll event, such as with the ScrollableControl.Scroll event.
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ScrollableControl.Scroll 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 a type that inherits from ScrollableControl, such as a Panel or ContainerControl. Then name the instance ScrollableControl1 and ensure that the event handler is associated with the ScrollableControl.Scroll event.
