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} />
