Gets or sets a value that indicates whether elements that support the IScrollInfo interface are allowed to scroll.
Assembly: PresentationFramework (in PresentationFramework.dll)
Content in a ScrollViewer can be scrolled in terms of physical units or logical units. Physical units are device independent pixels. Logical units are used for scrolling items within an ItemsControl. The default behavior of the ScrollViewer is to use physical units to scroll its content. However, in cases where the is set to true, the content could use logical units to scroll. For example, ListBox, ListView, and other controls that inherit from ItemsControl use logical units to scroll. If is true, the values of the ExtentHeight, ScrollableHeight, ViewportHeight, and VerticalOffset properties are number of items, instead of physical units.
If you require physical scrolling instead of logical scrolling, wrap the host Panel element in a ScrollViewer and set its property to false. Physical scrolling is the default scroll behavior for most Panel elements.
