Hi Deepak, 
 
We have checked the reported queries. Please find the details as following. 
 
Queries 
Details 
Set background color to each group based on the level in grid 
You can achieve your requirement by using DrawCell eventby checking the RowType as CaptionCoveredRow 
 
private void SfDataGrid1_DrawCell(object sender, DrawCellEventArgs e) 
{ 
    if (e.DataRow.RowType == RowType.CaptionCoveredRow) 
    { 
        var level = (e.DataRow.RowData as Group).Level; 
        if (level == 1) 
            e.Style.BackColor = Color.YellowGreen; 
        else if (level == 2) 
            e.Style.BackColor = Color.AliceBlue; 
        else if (level == 3) 
            e.Style.BackColor = Color.IndianRed; 
    } 
} 
 
You can refer the following user guide documentation to customize the caption summary cell. 
In Group result, field name with Field value of selected field for Grouping is required.  
By default our SfDataGrid displays the group header with column name along with summary value. 
 
You can refer the following screen shot.

You can achieve this requirement by customizing the converter. You can refer the following code snippets. 
 
Exporting to excel. 
public class SfDataGridExcelConvereter    : DataGridToExcelConverter 
{ 
    int level = -1; 
    protected override void ExportGroupCaptionToExcel(SfDataGrid grid, ICollectionViewAdv view, IWorksheet sheet, ExcelExportingOptions excelExportingOptions, Group group) 
    { 
        level = group.Level; 
        base.ExportGroupCaptionToExcel(grid, view, sheet, excelExportingOptions, group); 
    } 
 
    protected override void ExportSummaryCellToExcel(SfDataGrid grid, IRange summaryRange, ExportCellType exportCellType, string summaryDisplayText, object exportNodeEntry, string columnName, ExcelExportingOptions excelExportingOptions) 
    { 
        base.ExportSummaryCellToExcel(grid, summaryRange, exportCellType, summaryDisplayText, exportNodeEntry, columnName, excelExportingOptions); 
        if (level == 1) 
            summaryRange.CellStyle.FillBackground = ExcelKnownColors.Green; 
        else if (level == 2) 
            summaryRange.CellStyle.FillBackground = ExcelKnownColors.Blue; 
        else if (level == 3) 
            summaryRange.CellStyle.FillBackground = ExcelKnownColors.Red; 
        level = -1; 
    } 
} 
 
private void ExportToExcel_Click(object sender, EventArgs e) 
{ 
    var options = new ExcelExportingOptions(); 
    var excelConverter = new SfDataGridExcelConvereter(); 
    var excelEngine = excelConverter.ExportToExcel(sfDataGrid1, sfDataGrid1.View, options);             
    var workBook = excelEngine.Excel.Workbooks[0]; 
    workBook.SaveAs("Sample.xlsx"); 
} 
 
 
Exporting to PDF 
 
public class SfDataGridPDFConvereter    : DataGridToPdfConverter 
{ 
    int level = -1; 
    protected override void ExportGroupCaptionToPdf(SfDataGrid sfgrid, PdfGrid pdfGrid, ICollectionViewAdv view, PdfExportingOptions pdfExportingOptions, Group group) 
    { 
        level = group.Level; 
        base.ExportGroupCaptionToPdf(sfgrid, pdfGrid, view, pdfExportingOptions, group);             
    } 
         
    protected override void ExportSummaryCellToPdf(SfDataGrid sfGrid, PdfGridCell pdfGridCell, PdfExportingOptions pdfExportingOptions, ExportCellType exportCellType, string summaryDisplayText, object exportNodeEntry, string columnName) 
    {             
        base.ExportSummaryCellToPdf(sfGrid, pdfGridCell, pdfExportingOptions, exportCellType, summaryDisplayText, exportNodeEntry, columnName); 
        if (level == 1) 
            pdfGridCell.Style.BackgroundBrush = PdfBrushes.YellowGreen; 
        else if (level == 2) 
            pdfGridCell.Style.BackgroundBrush = PdfBrushes.AliceBlue; 
        else if (level == 3) 
            pdfGridCell.Style.BackgroundBrush = PdfBrushes.IndianRed; 
        level = -1; 
    } 
} 
 
private void ExportToPDF_Click(object sender, EventArgs e) 
{ 
    PdfExportingOptions options = new PdfExportingOptions();            
    var pdfConverter = new SfDataGridPDFConvereter(); 
    var document = pdfConverter.ExportToPdf(sfDataGrid1,options);                       
    document.Save("Sample.pdf"); 
}     
 
 
We have attached the sample for your reference and it is available in the following location.  
 
Please let us know if you would require further assistance.
