How to Set Page Breaks While Exporting WinForms GridControl to PDF?

This example demonstrates how to set page breaks while exporting WinForms GridControl to PDF.

Page breaks can be set while exporting GridControl as PDF by passing row count for each PDF page in the GridPDFConverter.ExportToPdf method. The PDF pages are merged as a single PDF file and finally saved.

private void Exportbutton_Click(object sender, EventArgs e)
{
    var converter = new GridPDFConverter();
    var lowest = 0;
 
    //Adding page breaks to a list.
    var rows = new List<int> {30, 63, 90, 130, 150};
 
    var pdfDocument = new PdfDocument();
    pdfDocument.Save("Sample.pdf");
    foreach (var rownumber in rows)
    {
        var pdf = new PdfDocument();
        var maximumRow = rownumber;
        converter.ExportToPdf(pdf, gridControl1, GridRangeInfo.Rows(lowest, maximumRow));
        var stream = new MemoryStream();
        pdf.Save(stream);
        var loadedDocument = new PdfLoadedDocument("Sample.pdf");
        loadedDocument = PdfDocumentBase.Merge(loadedDocument, new PdfLoadedDocument(stream)) as PdfLoadedDocument;
        loadedDocument.Save("Sample.pdf");
        loadedDocument.Close(true);
        stream.Dispose();
        lowest = maximumRow + 1;
    }
    var loadedDocument1 = new PdfLoadedDocument("Sample.pdf");
    loadedDocument1.Pages.RemoveAt(0);
    loadedDocument1.Save("Sample.pdf");
    Process.Start("Sample.pdf");
}
