Scrolls content logically to the left in response to a left click of the mouse wheel button.
Assembly: System.Windows (in System.Windows.dll)
You can override in a derived class to change how the stack panel responds to the mouse wheel left 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.
