{
    public MainPage()
    {
        InitializeComponent();
        sfGrid.CellRenderers.Remove("CaptionSummary");
        sfGrid.CellRenderers.Add("CaptionSummary", new CustomCaptionCellRenderer());
    }
}
public class CustomCaptionCellRenderer : DataGridCaptionSummaryCellRenderer
{
    protected override void OnSetCellStyle(DataColumnBase dataColumn)
    {
        base.OnSetCellStyle(dataColumn);

        if (dataColumn.ColumnElement != null && dataColumn.ColumnElement.Content is SfDataGridLabel label)
        {
            dataColumn.ColumnElement.Background = Colors.SkyBlue;

            label.HorizontalTextAlignment = TextAlignment.Start;
            label.FontSize = 16;
            label.FontAttributes = FontAttributes.Bold;
            label.TextColor = Colors.White;
