open-row

Description​

Fires when opening (expanding) a row

The action can be triggered if the treetoggle parameter of the columns property is enabled.

Usage​

"open-row": ({
    id: string | number,
    nested?: boolean
}) => boolean|void;

Parameters​

The callback of the action takes an object with the following parameters:

  • id - (required) the id of a row that have nested rows
  • nested - (optional) if set to true, all nested items will be expanded
note

If id is set to 0 and nested to true, all rows in the table will be expanded

Example​

In the example below we make all rows expand on a button click. To do this, we get access to the Grid api via bind:api and use the api.exec() method to trigger the open-rowaction on a button click.

Example:

<script>
  import { Button } from "wx-svelte-core"; // import the Button component
  import { Grid } from "wx-svelte-grid";
