VirtualizingStackPanel.MouseWheelUp Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Scrolls content logically upward in response to an upward click of the mouse wheel button.

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

Syntax

'Declaration
Public Overridable Sub MouseWheelUp
public virtual void MouseWheelUp()

Implements

IScrollInfo.MouseWheelUp()

Remarks

You can override MouseWheelUp in a derived class to change how the stack panel responds to the mouse wheel up action.

If you require physical scrolling instead of logical scrolling, wrap the VirtualizingStackPanel in a ScrollViewer and set its CanVerticallyScroll or CanHorizontallyScroll property to false. In this case, the ScrollViewer provides scrolling, and virtualization is disabled.
