Scrolling

If the RadListDataItems cannot fit in the pop up, a vertical scroll bar appears so that they can be scrolled and later selected. RadListControl provides three scrolling modes that can be used depending on user preferences: Discrete, Smooth and Deferred. It is controlled by the ScrollMode property.

ScrollMode	Description	Scrolling Behavior
Discrete	Defines scrolling by only one item at a time.
Smooth	Sets scrolling by pixel, meaning that an item can be partially visible.
Deferred	Does not cause GUI updates until the user finishes the scrolling operation.

KineticScrolling

This feature ensures that the control is ready for modern touch-screen applications. It can be attached by simply setting the EnableKineticScrolling property to true.

Programmatically Scrolling

The RadListControl.ListElement provides out of the box functionality for programmatically scrolling its content. The available methods are:

• ScrollToItem: Scrolls to a specific item.

• ScrollToActiveItem: Scrolls to the active item if it is not null and if it is not fully visible.
