RowSelectionManager class

Processes the row selection operation in SfDataGrid.

You can override the available methods in this class to customize the selection operation in DataGrid and set the instance to the SfDataGrid.selectionManager.

The following code shows how to change the Enter key behavior by overriding the handleKeyEvent() method in RowSelectionManager,

final CustomSelectionManager _customSelectionManager = CustomSelectionManager();
@override
Widget build(BuildContext context){
  return MaterialApp(
      home: Scaffold(
          body: SfDataGrid(
            source: _employeeDataSource,
            columns: [
                GridColumn(columnName: 'id', label = Text('ID')),
                GridColumn(columnName: 'name', label = Text('Name')),
                GridColumn(columnName: 'designation', label = Text('Designation')),
                GridColumn(columnName: 'salary', label = Text('Salary')),
            ],
            selectionMode: SelectionMode.multiple,
            navigationMode: GridNavigationMode.cell,
            selectionManager: _customSelectionManager,
          ))
  );
}
class CustomSelectionManager extends RowSelectionManager{
    @override
    void handleKeyEvent(RawKeyEvent keyEvent) {
        if(keyEvent.logicalKey == LogicalKeyboardKey.enter){
            //apply your logic
            return;
        }
        super.handleKeyEvent(keyEvent);
    }
}

inherited

handleDataGridSourceChanges() → void

Called when the selection is programmatically changed using SfDataGrid.controller.

override

handleKeyEvent(RawKeyEvent keyEvent) → Future<void>

Processes the selection operation when SfDataGrid receives raw keyboard event.

override

handleTap(RowColumnIndex rowColumnIndex) → void

Processes the selection operation when tap a cell.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notifyListeners() → void

Call all the registered listeners.

inherited

onGridSelectionModeChanged() → void

Called when the SfDataGrid.selectionMode is changed at run time.

override

onSelectedIndexChanged() → void

Called when the selectedIndex property in SfDataGrid.controller is changed.

override

onSelectedRowChanged() → void

Called when the selectedRow property in SfDataGrid.controller is changed.

override

onSelectedRowsChanged() → void

Called when the selectedRows property in SfDataGrid.controller is changed.

override

removeListener(VoidCallback listener) → void
