Example​

The example below shows how to output the selected row ID by obtaining it via the api.getState() method:

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

    const columns = [
        { id: "id", width: 50 },
        { id: "city", header: "City", width: 160 },
        { id: "firstName", header: "First Name" },
        { id: "lastName", header: "Last Name" },
        { id: "companyName", header: "Company" },
    ];

    let api;
    s = 0;
    const updateSelected = () => (s = api.getState().selected);
</script>

<p>Click a cell to select a row. The selected row: {s || 'none'}</p>

<div style="height: 415px; ">
 <Grid {data} {columns}
 bind:api
 on:select-row={updateSelected} />
</div>
