React DeferRendering API

The DeferRendering is a UI component that waits for its content to be ready before rendering it. While the content is getting ready, the DeferRendering displays a loading indicator.

import DeferRendering from "devextreme-react/defer-rendering"
Selector: DeferRendering

IMPORTANT

This component is deprecated. To defer rendering in other components, enable the corresponding deferRendering properties. You can also create a loading indicator and display it based on your logic.
