Row Selection
In this demo, the DataGrid allows users to select only one row at a time. To enable this mode, set the selection.mode option to "single".
You can access the selected row data from the onSelectionChanged function. In this demo, this function fetches the selected row's information and displays it under the grid.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
