VirtualizingStackPanel.MouseWheelDown Method

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

Scrolls content logically downward in response to a downward click of the mouse wheel button.

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

Syntax

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

Implements

IScrollInfo.MouseWheelDown()

Remarks

You can override MouseWheelDown in a derived class to change how the stack panel responds to the mouse wheel down 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.
