Multiple Record Selection API
Documentation
The DataGrid widget provides a flexible selection API. In this demo, when you choose a title from the drop-down menu above the DataGrid, the selectRows(keys) method selects those rows that contain the chosen title. A click on the Clear Selection button clears the selection by calling the clearSelection() method.
Thank you!
