A helper element that enables a "stashed-based" lazy loading approach for the content of the sap.uxap.ObjectPageSubSection control.
ObjectPageLazyLoader
is intended to be used in a declarative way only (for example, in a view) with the stashed
property set to true
, and is recommended to be used only once per subsection as its sole content.
ObjectPageLazyLoader
utilizes UI5's stashing mechanism and is a lightweight alternative to the native block-based Lazy Loading of the ObjectPageLayout
. Wrapping the content of a subsection in an ObjectPageLazyLoader
with stashed=true
will make the content unstash automatically as the user scrolls.
Note: Subsections are required to have an ID when used with ObjectPageLazyLoader
.
Constructor for a new ObjectPageLazyLoader
.
Accepts an object literal mSettings
that defines initial property values, aggregated and associated objects as well as event handlers. See sap.ui.base.ManagedObject#constructor for a general description of the syntax of the settings object.
