Hi Дмитрий Шелковников,
You can look at this example how to update data in the Grid dynamically: https://www.htmlelements.com/demos/grid/datagrid-update-data/. If you want to update the data set, you can create a new dataAdapter instance and set the Grid’s dataSource property to it. Alternatively, you can use the Grid API to make updates: https://www.htmlelements.com/demos/grid/live-update/
