    I am trying to use the Data Grid in an existing Aurelia 2 application that uses Shadow DOM exclusively. If I test the Data Grid without a Shadow Root host, I get the following example:  https://gist.dumber.app/?gist=ea762782caa0c4bf225ce55e65f78d33

    However, if I try and use the Data Grid that is hosted already by a parent Shadow Root, I get the following failure:  https://gist.dumber.app/?gist=45fa3a1a5cdc000b300a892741533f18

    It appears that the selector used to find the element does NOT pierce the Shadow DOM and this explains why we have a failure in the second.

    Please advise how this should work,

    Matt

    Hi Matt,

    You can use this approach:

    export class MyApp {
    message = 'Hello Aurelia 2!';
    attaching() {
    document.addEventListener('readystatechange', () => {
    if (document.readyState === "complete") {
    this.grid.dataSource =new Smart.DataAdapter(
    {
    dataSource: [
