this one helps. scrollToColumn will guarantee that the Grid's column will be visible. How can it be rendered so that it's centered in the grid? , You can do this using the scrollToAlignment property:

How to render whole Grid in DOM if I need in react-virtualized?
Date : March 29 2020, 07:55 AM
Any of those help I'm not an expert on react-virtualized, but it seems that defining a custom overscanIndicesGetter function may the simplest solution. Per the docs: overscanIndicesGetter const overscanIndicesGetter = ({cellCount}) => ({
overscanStartIndex: 0,
overscanStopIndex: cellCount - 1,
});
const { Grid } = window.ReactVirtualized;
const data = Array.from(new Array(1000)).map((_, i) => i);
const Cell = ({key, rowIndex, style}) =>
<div key={key} style={style}>{data[rowIndex]}</div>;
const overscanIndicesGetter = ({cellCount}) => ({
overscanStartIndex: 0,
overscanStopIndex: cellCount - 1,
});
const App = ({data}) => (
<Grid
cellRenderer={Cell}
columnCount={1}
columnWidth={100}
rowCount={data.length}
rowHeight={30}
height={300}
width={300}
overscanIndicesGetter={overscanIndicesGetter}
/>
);
ReactDOM.render(<App data={data}/>, document.querySelector('div'));

react virtualized grid sort icon
Date : March 29 2020, 07:55 AM
hope this fix your issue Sounds like you want the header icons to work similarly to how react-virtualized Table headers work. The basic approach to this requires you to track both sort-by and sort-direction at the level of your Grid. You seem to be tracking it in component state at the level of a column which will run into the issue you've mentioned.

Sortable rows using react-sortable-hoc and react-virtualized's MultiGrid
Date : March 29 2020, 07:55 AM
I wish this helpful for you I've been trying to make the react-virtualized's MultiGrid sortable. In the end, I adjusted the MultiGrid's Grids to get my desired effect. However, when sorting, the rows don't transition properly and always move to the extremes (topmost or bottom most). Heres a codesandbox demo of what I've made so far: https://codesandbox.io/s/5kl4z8olrn , Styles were needed for the rows to properly sort and transition.

React Click/Mouse Event Handling [react-sortable-hoc, material-ui, react-virtualized]
Tag : reactjs , By : Jason Jennings
Date : March 29 2020, 07:55 AM
around this issue i am working on same kind of application where i want to perform some operation when i clicked somthing on cell and also made them sortable. it can be achieved in two ways add delay prop pressDelay props in SortableContainer HOC. docs let's say pressDelay=500. what this will do is that if you hold your click for 500ms the row will become sortable otherwise just normal click event will fire.in my opinion this will work just fine import { SortableHandle } from 'react-sortable-hoc';
const DragHandle = SortableHandle(() => columns[0]);
return (
<div
{...a11yProps}
className={className}
key={key}
role='row'
style={style}>
<DragHandle />
{columns.slice(1, columns.length)}
</div>
);
