dynamic

Description​

Optional. Enables dynamic data loading

Usage​

dynamic?: { rowsCount: number };

Parameters​

  • rowsCount - the number of all rows in the dataset

Example​

In the example below we use the dynamic property to enable dynamic data loading and specify the number of all rows in a dataset. The data-request action is triggered while scrolling and we add the event handler that receives the row.start and row.end values and loads data.

import { Grid } from "wx-react-grid";
import { getData } from "./common/data";
import { useRef } from "react";

const { allData, columns } = getData();

export default function App() {
    let data = [];
    const api = useRef(null);

    function dataProvider(ev) {
        const { requestData } = ev.detail;
        const { row } = requestData;

        if (row) data = allData.slice(row.start, row.end);
    }

    let rowsCount = 500;

    return (
        <Grid 
            data={allData}
            columns={columns}
            dynamic={{ rowsCount }}
            onDataRequest={dataProvider}
            api={api}
        />
    );
}
