The PagedControl class defines the basic
functionality for controls that use internal pagination, and can
divide their content over multiple pages. These includes the
List, LiteralText,
ObjectList, and TextView
controls, all of which derive from this class. To create a custom
control that supports internal pagination, derive it from
PagedControl. Override the
ItemWeight property so that it returns the
approximate weight of an individual item in the control. (The default
weight is 100, which corresponds to a single line on the device using
the default unit system.) Then, when rendering the
control's output, call the
FirstVisibleItemIndex( ) method, which will tell
you the first item to render, and the VisibleItemCount(
) method to determine how many items to render. Your paged
control will automatically fire the LoadItems
event as needed.

PagedControl  : MobileControl {
