### Getting row details

To retrieve the details of a row in the DataGrid, use the [controller](https://pub.dev/documentation/syncfusion_flutter_datagrid/latest/datagrid/SfDataGrid/controller.html) property. Create an instance of the [DataGridController](https://pub.dev/documentation/syncfusion_flutter_datagrid/latest/datagrid/DataGridController-class.html) and assign it to the controller property of the DataGrid. To obtain the details of a row, use the `getRowDetails` method from the controller, providing the index as the parameter. This method returns a `DataGridRowDetails`, which includes the following properties:

* [rowType](https://pub.dev/documentation/syncfusion_flutter_datagrid/latest/datagrid/RowType.html) – Returns the type of the row (e.g., dataRow, headerRow).

* [dataGridRow](https://pub.dev/documentation/syncfusion_flutter_datagrid/latest/datagrid/DataGridRow-class.html) – Provides the DataGridRow corresponding to the specified index.

* isSelected – Indicates whether the row is currently selected.

## Customizing selection behavior

To perform custom actions apart from the functionalities mentioned in the above tables for key press actions of the keyboard, implement your custom actions in the [handleKeyEvent()](https://pub.dev/documentation/syncfusion_flutter_datagrid/latest/datagrid/RowSelectionManager/handleKeyEvent.html) override of the custom written selection manager class derived from [RowSelectionManager](https://pub.dev/documentation/syncfusion_flutter_datagrid/latest/datagrid/RowSelectionManager-class.html) and assign it to the [SfDataGrid.selectionManager](https://pub.dev/documentation/syncfusion_flutter_datagrid/latest/datagrid/SfDataGrid/selectionManager.html) property.
