Virtuoso Grid API Reference
All properties are optional - by default, the component will render empty.
If you are using TypeScript and want to use correctly typed component ref, you can use VirtuosoGridHandle types.

Properties
atBottomStateChange
• Optional atBottomStateChange: (atBottom: boolean) => void
Defined in components.tsx:282
Called with true / false when the list has reached the bottom / gets scrolled up.
Can be used to load newer items, like tail -f.
atTopStateChange
• Optional atTopStateChange: (atTop: boolean) => void
Defined in components.tsx:287
Called with true / false when the list has reached the top / gets scrolled down.
components
• Optional components: GridProps["components"]
Defined in components.tsx:236
Use the components property for advanced customization of the elements rendered by the list.
computeItemKey
• Optional computeItemKey: GridProps["computeItemKey"]
Defined in components.tsx:248
If specified, the component will use the function to generate the key property for each list item.
endReached
• Optional endReached: (index: number) => void
Defined in components.tsx:266
Gets called when the user scrolls to the end of the list. Receives the last item index as an argument. Can be used to implement endless scrolling.
isScrolling
• Optional isScrolling: (isScrolling: boolean) => void
Defined in components.tsx:260
Called when the list starts/stops scrolling.
itemClassName
• Optional itemClassName: string
Defined in components.tsx:302
Sets the grid items' className
itemContent
• Optional itemContent: GridProps["itemContent"]
Defined in components.tsx:231
Set the callback to specify the contents of the item.
listClassName
• Optional listClassName: string
Defined in components.tsx:297
Sets the className for the list DOM element
overscan
• Optional overscan: number | { main: number ; reverse: number }
Defined in components.tsx:243
Set the overscan property to make the component "chunk" the rendering of new items on scroll. The property causes the component to render more items than the necessary, but reduces the re-renders on scroll. Setting { main: number, reverse: number } lets you extend the list in both the main and the reverse scrollable directions.
rangeChanged
• Optional rangeChanged: (range: ListRange) => void
Defined in components.tsx:276
Called with the new set of items each time the list items are rendered due to scrolling.
scrollSeekConfiguration
• Optional scrollSeekConfiguration: ScrollSeekConfiguration | false
Defined in components.tsx:255
Use to display placeholders if the user scrolls fast through the list.
Set components.ScrollSeekPlaceholder to change the placeholder content.
scrollerRef
• Optional scrollerRef: (ref: HTMLElement | null) => any
Defined in components.tsx:292
Provides access to the root DOM element
startReached
• Optional startReached: (index: number) => void
Defined in components.tsx:271
Called when the user scrolls to the start of the list.
totalCount
• totalCount: GridProps["totalCount"]
Defined in components.tsx:226
The total amount of items to be rendered.
useWindowScroll
• Optional useWindowScroll: boolean
Defined in components.tsx:307
Uses the document scroller rather than wrapping the grid in its own.
