How to show the context menu while adding a new record using addNewRow in WinForms DataGrid?

sfDataGrid.TableControl.MouseUp += SfDataGrid_MouseUp;
 
//Get the record context while AddingNewRow menu by customization 
private void SfDataGrid_MouseUp(object sender, MouseEventArgs e)
{
            // get the row and column index based on the pointer position 
            var rowColIndex = sfDataGrid.TableControl.PointToCellRowColumnIndex(e.Location);
 
            //Check the condition is AddNewRow and Only show the context menu while pressing right button of Mouse
            if (e.Button == MouseButtons.Right && sfDataGrid.IsAddNewRowIndex(rowColIndex.RowIndex) && this.sfDataGrid.RecordContextMenu != null && !rowColIndex.IsEmpty)
            {
                ContextMenuStrip contextMenu = null;
 
                //set the Record contextMenu for AddNewRow
                contextMenu = this.sfDataGrid.RecordContextMenu;
                //get the location 
                var location = this.sfDataGrid.TableControl.PointToScreen(e.Location);
                if (contextMenu != null)
                {
                    //show the ContextMenu for AddNewRow
                    contextMenu.Show(location);
                }
            }
}
