You can export the SfDataGrid to PDF by using the extension methods provided in the Syncfusion.Maui.DataGrid.Exporting namespace.

• ExportToPdf
• ExportToPdfGrid

The following code illustrates how to create and display a SfDataGrid in view.

XAML

<StackLayout>
    <Button Text="Export" Clicked="ExportToPDF_Clicked"/>
    <syncfusion:SfDataGrid  x:Name="dataGrid"
                            AutoGenerateColumnsMode="None"
                            VerticalOptions="FillAndExpand"
                            ColumnWidthMode="Auto"
                            ItemsSource="{Binding OrderInfoCollection}" >
        <syncfusion:SfDataGrid.Columns>
            <syncfusion:DataGridNumericColumn MappingName="OrderID" HeaderText="Order ID" Format="d"/>
            <syncfusion:DataGridTextColumn MappingName="CustomerID" HeaderText="Customer ID"/>
            <syncfusion:DataGridTextColumn MappingName="Customer" HeaderText="Customer"/>
            <syncfusion:DataGridTextColumn MappingName="ShipCountry" HeaderText="Ship Country"/>
            <syncfusion:DataGridTextColumn MappingName="ShipCity" HeaderText="Ship City"/>
        </syncfusion:SfDataGrid.Columns>
    </syncfusion:SfDataGrid>
</StackLayout>

ExportToPdf

To export the data to PDF, you can use the DataGridPdfExportingController.ExportToPdf method, which requires passing the SfDataGrid as an argument.

C#

private void ExportToPDF_Clicked(object sender, EventArgs e)
{
    MemoryStream stream = new MemoryStream();
    DataGridPdfExportingController pdfExport = new DataGridPdfExportingController();
    DataGridPdfExportingOption option = new DataGridPdfExportingOption();
    var pdfDoc = new PdfDocument();
    pdfDoc = pdfExport.ExportToPdf(this.dataGrid, option);
    pdfDoc.Save(stream);
    pdfDoc.Close(true);
    SaveService saveService = new();
    saveService.SaveAndView("ExportFeature.pdf", "application/pdf", stream);
}

ExportToPdfGrid

To export the data to PDF, you can also use the DataGridPdfExportingController.ExportToPdfGrid method, which requires passing the SfDataGrid as an argument.

C#

private void ExportToPDF_Clicked(object sender, EventArgs e)
{
    DataGridPdfExportingController pdfExport = new DataGridPdfExportingController();
    MemoryStream stream = new MemoryStream();
    var pdfDoc = new PdfDocument();
    PdfPage page = pdfDoc.Pages.Add();
    var exportToPdfGrid = pdfExport.ExportToPdfGrid(this.dataGrid, this.dataGrid.View, new DataGridPdfExportingOption()
    {
        CanFitAllColumnsInOnePage = false,

    }, pdfDoc);
    exportToPdfGrid.Draw(page, new Syncfusion.Drawing.PointF(10, 10));
    pdfDoc.Save(stream);
    pdfDoc.Close(true);
    SaveService saveService = new();
    saveService.SaveAndView("ExportFeature.pdf", "application/pdf", stream);
}

NOTE

SfDataGrid cannot export the DataGridTemplateColumn to PDF or Excel due to the inability to access the loaded views and accurately capture their content and layout in a specific range and value from the DataGridTemplateColumn.

Exporting options

Exclude columns when exporting

By default, all columns, including hidden columns, are exported to PDF in the SfDataGrid. If you want to exclude specific columns during PDF export, you can add those columns to the DataGridPdfExportingOption.ExcludeColumns list.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
var list = new List<string>();
list.Add("OrderID");
list.Add("CustomerID");
option.ExcludedColumns = list;

Obtaining a PDF document

The DataGridPdfExportingOption.PdfDocument enables the export of the SfDataGrid to either an existing or a new PDF document.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
PdfDocument pdfDocument = new PdfDocument();
pdfDocument.Pages.Add();
pdfDocument.Pages.Add();
pdfDocument.Pages.Add();
option.StartPageIndex = 1;
option.PdfDocument = pdfDocument;

Obtaining columns for customization

By utilizing the property Columns, you can retrieve or modify the System.Collections.IEnumerable columns collection, which includes all the columns intended for export. Any columns listed in the ExcludedColumns List will not be included in the Columns collection.

Column header on each page

To display or conceal the column headers on every page of the exported PDF document, you can use the DataGridPdfExportingOption.CanRepeatHeaders property. By default, its value is set to true.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.CanRepeatHeaders = true;

Customize header, stacked header, groups, table summary and unbound row when exporting

Export groups

By default, all the groups in the data grid will be exported to PDF document. To export the data grid without groups, set the DataGridPdfExportingOption.CanExportGroups property to false.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.CanExportGroups = true;

Exclude column header while exporting

By default, the column headers will be exported to PDF document. To export the SfDataGrid without the column headers, set the DataGridPdfExportingOption.CanExportHeader property to false.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.CanExportHeader = false;

Export stacked header

By default, the column headers will not be exported to PDF document. To export the SfDataGrid with the column headers, set the DataGridPdfExportingOption.CanExportStackedHeaders property to true.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.CanExportStackedHeaders = true;

Export table summaries

By default, table summaries in the data grid will be exported to PDF. To export the SfDataGrid without table summaries, set the DataGridPdfExportingOption.CanExportTableSummary property to false.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.CanExportTableSummary = true;

Export group summaries

By default, the GroupSummary rows in the data grid will be exported to PDF. To export the SfDataGrid without group summaries, set the DataGridPdfExportingOption.CanExportGroupSummary property to false.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.CanExportGroupSummary = true;

Export unbound row

By default, the unbound rows in the data grid will not be exported to PDF. To export the SfDataGrid with unbound rows, set the DataGridPdfExportingOption.CanExportUnboundRow property to true.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.CanExportUnboundRow = true;

Exporting the selected rows of SfDataGrid

The SfDataGrid allows you to export only the currently selected rows in the grid to a document using the DataGridPdfExportingController.ExportToPdf method. To achieve this, you need to pass the instance of the SfDataGrid and the SfDataGrid.SelectedRows collection as arguments to the method.

Please refer to the code below for exporting only the selected rows to a PDF document:

C#

ObservableCollection<object> selectedItems = dataGrid.SelectedRows;
var pdfDoc = pdfExport.ExportToPdf(this.dataGrid, selectedItems);

Export all columns in one page

Gets or sets a value indicating whether all the columns should be fitted on a page. To export all the columns in one page, set the DataGridPdfExportingOption.CanFitAllColumnsInOnePage property to true.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.CanFitAllColumnsInOnePage = true;

Exporting the grid from a specified page and point

The SfDataGrid allows exporting data to a specific starting position on a particular PDF page using the following options:

• StartPageIndex
• StartPoint

StartPageIndex

The SfDataGrid allows you to export data to a specific page in a PDF document by using the DataGridPdfExportingOption.StartPageIndex property.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();

Customizing borders

The SfDataGrid provides the ability to customize grid borders by utilizing the DataGridPdfExportingOption.GridLineType property.

• Both
• Horizontal
• Vertical
• None

Both

Set the DataGridPdfExportingOption.GridLineType as GridLineType.Both to export the data grid with both horizontal and vertical borders.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.GridLineType = GridLineType.Both;

Set the DataGridPdfExportingOption.GridLineType to GridLineType.None to export the data grid without borders.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.GridLineType = GridLineType.None;

Setting header and footer

The SfDataGrid offers a way to include additional content at the top (header) or bottom (footer) of the page when exporting to PDF. This can be achieved by handling the DataGridPdfExportingController.HeaderAndFooterExporting event.

To insert a string in the header or footer, you need to use the PdfHeaderFooterEventHandler. By setting the PdfPageTemplateElement as PdfHeaderFooterEventArgs.PdfDocumentTemplate.Top, you can load the content at the top of the page. Similarly, setting the PdfPageTemplateElement as PdfHeaderFooterEventArgs.PdfDocumentTemplate.Bottom will load the content at the bottom of the page.

C#

DataGridPdfExportingController pdfExport = new DataGridPdfExportingController();
pdfExport.HeaderAndFooterExporting += PdfExport_HeaderAndFooterExporting;
private void PdfExport_HeaderAndFooterExporting(object sender, DataGridPdfHeaderFooterEventArgs e)
{
    PdfFont font = new PdfStandardFont(PdfFontFamily.TimesRoman, 20f, PdfFontStyle.Bold);
    var width = e.PdfPage.GetClientSize().Width;
    PdfPageTemplateElement header = new PdfPageTemplateElement(width, 38);
    header.Graphics.DrawString("Order Details", font, PdfPens.Black, 70, 3);
    e.PdfDocumentTemplate.Top = header;

    PdfPageTemplateElement footer = new PdfPageTemplateElement(width, 38);
    footer.Graphics.DrawString("Order Details", font, PdfPens.Black, 70, 3);
    e.PdfDocumentTemplate.Bottom = footer;
}

Change PDF page orientation

You have the option to change the page orientation of a PDF document during the export process. The default page orientation is portrait.

To modify the page orientation, you can export the PDF grid value using the ExportToPdfGrid method. Afterwards, you can draw the PDF grid into a PDF document by adjusting the PageSettings.Orientation property of the PDF document.

C#

var pdfDoc = new PdfDocument();
option.PdfDocument = pdfDoc;
pdfDoc.PageSettings.Orientation = PdfPageOrientation.Landscape;

Row height and column width customization

ExportColumnWidth

By default, the columns of the data grid will be exported to PDF using the DataGridPdfExportingOption.DefaultColumnWidth value. If you want to export the data grid to PDF with precise column widths, you can set the `DataGridPdfExportingOption.CanExportColumnWidth to true.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.CanExportColumnWidth = true;

ExportRowHeight

By default, the data grid rows will be exported to PDF using the DataGridPdfExportingOption.DefaultRowHeight value. If you want to export the data grid to PDF with the exact row heights, you can set the DataGridPdfExportingOption.CanExportRowHeight to true.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.CanExportRowHeight = true;

DefaultColumnWidth

The SfDataGrid allows customizing column width in the PDF document using the DataGridPdfExportingOption.DefaultColumnWidth property. The DefaultColumnWidth value will be applied to all the columns in the document.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.DefaultColumnWidth = 150;
option.CanExportColumnWidth = false;

DefaultRowHeight

The SfDataGrid allows customizing row height in the PDF document using the DataGridPdfExportingOption.DefaultRowHeight property. The DefaultRowHeight value will be applied to all the rows in the document.

C#

DataGridPdfExportingOption option = new DataGridPdfExportingOption();
option.DefaultRowHeight = 80;
option.CanExportRowHeight = true;

Events

The SfDataGrid provides the following events for exporting:

• RowExporting : This event is raised when exporting a row during execution.
• CellExporting : This event is raised when exporting a cell during execution.

RowExporting

The DataGridRowPdfExportingEventHandler delegate allows for customizing the styles of record rows and group caption rows. The RowExporting event is triggered with DataGridRowPdfExportingEventArgs, which contains the following properties:

• PdfGrid: Customizes the properties of the pdfGrid, such as Background, CellPadding, CellSpacing, and more.
• PdfRow: Specifies the PDFGridRow to be exported and allows customization of the properties of a particular row.
• Record: Retrieves the collection of exported underlying data objects.
• RowType: Specifies the row type using the ExportRowType enum. It checks the row type and applies different styles based on the type.

You can use this event to customize the properties of the grid rows that are exported to PDF. The following code example demonstrates how to change the background color of the record rows and caption summary rows during the export process.

C#

pdfExport.RowExporting += pdfExport_RowExporting; 
void pdfExport_RowExporting (object sender, DataGridRowPdfExportingEventArgs e)
{
    if (e.RowType == ExportRowType.Record) {
        if ((e.Record.Data as OrderInfo).IsClosed)
            e.PdfRow.Style.BackgroundBrush = PdfBrushes.Yellow;
        else
        e.PdfRow.Style.BackgroundBrush = PdfBrushes.LightGreen;
    }
}

CellExporting

The DataGridCellPdfExportingEventHandler delegate allows for customizing the styles of header cells, record cells, and group caption cells. The CellExporting event is triggered with DataGridCellPdfExportingEventArgs, which contains the following properties:

• CellType: Specifies the cell type using the ExportCellType enum. It checks the cell type and applies different cell styles based on the type.

• CellValue: Contains the actual exported value used to format the PDF using the Range property.

• ColumnName: Specifies the column name (MappingName) of the exporting cell. It applies formatting for a particular column by checking the ColumnName.

• Handled: Determines whether the cell is exported to PDF or not.

• PdfGrid: Specifies the PDFGridCell to be exported. It customizes properties such as Background, Foreground, Font, Alignment, etc., for a particular cell.

• Record: Retrieves the collection of underlying data objects being exported.

You can use this event to customize the properties of grid cells that are exported to PDF. The code example below demonstrates how to customize the background color, Text color, and cell value of header cells, record cells, and caption summary cells during the export process.

C#

pdfExport.CellExporting += pdfExport_CellExporting;  
void pdfExport_CellExporting(object sender, DataGridCellPdfExportingEventArgs e)
{
    if (e.CellType == ExportCellType.HeaderCell)
    {
        e.PdfGridCell.Style.BackgroundBrush = PdfBrushes.Navy;
        e.PdfGridCell.Style.TextBrush = PdfBrushes.White;
        
    }

    if (e.CellType == ExportCellType.RecordCell)
    {
        e.PdfGridCell.Style.BackgroundBrush = PdfBrushes.LightBlue;
        e.PdfGridCell.Style.TextBrush = PdfBrushes.Black;
    }        
}

Cell customization

Customize the cells based on column name

You can customize the record cell style in a specific column based on the column name when exporting to PDF by handling the CellExporting event.

C#

pdfExport.CellExporting += PdfExport_CellExporting;
private void PdfExport_CellExporting(object sender, DataGridCellPdfExportingEventArgs e)
{
    if (e.CellType == ExportCellType.RecordCell && e.ColumnName == "OrderID")
    {
        e.PdfGridCell.Style.TextBrush = PdfBrushes.LightBlue;
    }
}
