Gets the type of scrollbar button that the end-user clicked on.
Type of the scroll button clicked.

Syntax

Visual Basic (Declaration)
Public ReadOnly Property ButtonType As ScrollBarButtonType

Visual Basic (Usage)	Copy Code
`Dim instance As ScrollBarEventArgs Dim value As ScrollBarButtonType value = instance.ButtonType`

C#
public ScrollBarButtonType ButtonType {get;}

Return Value

A ScrollBarButtonType enumeration value that represents the scrollbar element the end-user clicked on.

Example

In this example we override the default behavior when the user clicks on the reset button. Normally clicking on the reset button will result in the previous view being displayed, but using the AxisScrollBarClicked event we reset the view to its original state (i.e. no zooming). We only do this for the X axis of a chart area named "Default".
