Remarks
The IScrollInfo interface exposes access to methods that enable logical scrolling of child content as well as computing which child elements are visible. In addition, it defines properties used to define the scrollable region.
Logical scrolling enables scrolling to the next element in the logical tree. Physical scrolling, in contrast, scrolls content by a defined measurable increment in a specified direction. If you require physical scrolling instead of logical scrolling, wrap the host Panel element in a ScrollViewer and set the value of its CanContentScroll property to false.
