1 month ago Hi @abdulrehmananwar ,
In SfDataGrid, when you attempt to edit a cell, the focus shifts to the TextField loaded in the buildEditWidget. When the focus moves to the TextField, key events are no longer handled by the DataGrid. In SfDataGrid, we handle key events such as Enter (to submit the cell) and Tab (for navigation) during editing. If you want to handle the Ctrl+V key event, you will need to add a Focus widget as the parent of the TextField and perform the action as needed.
Additionally, we have attached the user guide documentation for key behaviors handled by SfDataGrid, along with code snippets for your reference. Please review these code snippets for more details and adapt them to suit your specific requirements.

Code snippets:
@override
Widget? buildEditWidget(DataGridRow dataGridRow,
RowColumnIndex rowColumnIndex, GridColumn column, CellSubmit submitCell) {
final String displayText = dataGridRow
.getCells()
.firstWhereOrNull((DataGridCell dataGridCell) =>
dataGridCell.columnName == column.columnName)
?.value
?.toString() ??
'';
newCellValue = null;
final bool isNumericType =
column.columnName == 'ID' || column.columnName == 'Salary';
return Container(
padding: const EdgeInsets.all(8.0),
alignment: isNumericType ? Alignment.centerRight : Alignment.centerLeft,
child: Focus(
onKeyEvent: (node, keyEvent) {
if (keyEvent.logicalKey == LogicalKeyboardKey.keyA) {
if (HardwareKeyboard.instance.isControlPressed) {
// Execute the necessary action.
return KeyEventResult.handled;
}
}
return KeyEventResult.ignored;
},
child: TextField(
autofocus: true,
controller: editingController..text = displayText,
textAlign: isNumericType ? TextAlign.right : TextAlign.left,
decoration: const InputDecoration(
contentPadding: EdgeInsets.fromLTRB(0, 0, 0, 8.0),
),
keyboardType:
isNumericType ? TextInputType.number : TextInputType.text,
onChanged: (String value) {
if (value.isNotEmpty) {
if (isNumericType) {
newCellValue = int.parse(value);
} else {
newCellValue = value;
}
} else {
newCellValue = null;
}
},
onSubmitted: (String value) {
submitCell();
},
),
),
);
