dynamic

Description​

Optional. Enables dynamic data loading

Usage​

dynamic?: { 
    rowCount: number,
    columnCount: number,
};

Parameters​

  • rowCount - (required) the number of all rows in the dataset
  • columnCount - (required) the number of columns in a 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 request-data action is triggered while scrolling and we add the event handler that receives the row.start and row.end values and loads data.

<script>
    import { Grid } from "wx-svelte-grid";
    import { getData } from "./common/data";
    const { allData, columns } = getData();

    let data = [];

    function dataProvider(ev) {
        const { row } = ev;

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

    let rowCount = 500;

</script>

<Grid 
    data={allData}
    {columns}
    dynamic={{rowCount}}
    onrequestdata={dataProvider} />
