SFDataGrid paging controller not working

Question

Hi,I have been trying to use the `DataPagerController` with my data table but I am unable to control anything with it. Is there currently an issue with the controller as to why it does not do any of the functions it has.Thanks,Will

Hi Will,Based on the provided information, we are not able to reproduce
your reported issue in a simple sample i.e., we have the DataGrid with two
buttons. By pressing the button, we navigate to the next and previous page
using the datapager controller. It’s
working fine on our side. Please check the
following code snippet and sample which we have tested.Code Snippet:

final
  DataPagerController _dataPagerController = DataPagerController();
  
    @override  Widget
build(BuildContext context) {    return
Scaffold(      appBar:
AppBar(        leading:
const BackButton(),        title:
const Text('Syncfusion DataPager'),      ),      body:
LayoutBuilder(builder: (context, constraints) {        return
Column(          children:
[            Row(              mainAxisAlignment:
MainAxisAlignment.spaceEvenly,              children:
[                MaterialButton(                    onPressed:
() {                      _dataPagerController.previousPage();                    },                    child:
const Text('Move To Previous page'),                   color:
Colors.cyan),                MaterialButton(                    onPressed:
() {                      _dataPagerController.nextPage();                    },                    child:
const Text('Move To Next page'),                    color:
Colors.cyan),              ],            ),            SizedBox(              height:
constraints.maxHeight - dataPagerHeight,              child:
SfDataGrid(                  source:
_employeeDataSource,                  selectionMode:
SelectionMode.multiple,                  columnWidthMode:
ColumnWidthMode.fill,                  columns:
getColumns),            ),            SizedBox(                height:
60,                child:
SfDataPager(                    pageCount:                        ((_employees.length
/ _rowsPerPage).ceil()).toDouble(),                    direction:
Axis.horizontal,                    delegate:
_employeeDataSource,                    controller: _dataPagerController))          ],        );      }),    );  }
