    public MainPage()
    {
        InitializeComponent();

        Title = "Employees List";
        EmployeeViewModel viewModel = new EmployeeViewModel();
        sfGrid = new SfDataGrid
        {
            GridLinesVisibility = GridLinesVisibility.Both,
            HeaderGridLinesVisibility = GridLinesVisibility.Both,
            ColumnWidthMode = ColumnWidthMode.Auto,
            AutoGenerateColumnsMode = AutoGenerateColumnsMode.None,
            ItemsSource = viewModel.Employees,
        };

        // Create a new style for the header
        var headerStyle = new Style(typeof(DataGridRowHeaderCell))
        {
            Setters =
            {
                new Setter { Property = DataGridRowHeaderCell.TextColorProperty, Value = Colors.Yellow },
                new Setter { Property = DataGridRowHeaderCell.FontAttributesProperty, Value = FontAttributes.Bold },
                new Setter { Property = DataGridRowHeaderCell.FontSizeProperty, Value = 25.0 },
            }
        };

        sfGrid.Columns.Add(new DataGridNumericColumn
        {
            MappingName = "EmployeeID",
            Format = "#",
            HeaderText = "Employee ID",
            HeaderStyle = headerStyle,

        });

        sfGrid.Columns.Add(new DataGridTextColumn
