How to Display the Wrapped HeaderTemplate Text in Exported PDF File in WPF DataGrid?

This sample illustrates how to display the wrapped HeaderTemplate text in exported PDF file in WPF DataGrid (SfDataGrid).

In DataGrid, you can wrap the header in exported PDF document by setting WordWrap property in PdfStringFormat class and apply the format to the PdfPageTemplateElement using PdfHeaderFooterEventHandler.

C#

private void Export_Click(object sender, RoutedEventArgs e)
{
    PdfExportingOptions options = new PdfExportingOptions();
    options.PageHeaderFooterEventHandler = PdfHeaderFooterEventHandler;
    var document = dataGrid.ExportToPdf(options);
    document.Save("Sample.pdf");
}

static void PdfHeaderFooterEventHandler(object sender, PdfHeaderFooterEventArgs e)
{
    var document = new PdfDocument();
    var page = document.Pages.Add();
    PdfPageTemplateElement header = new PdfPageTemplateElement(page.Graphics.ClientSize.Width, 38);
    var _headerFont = new PdfTrueTypeFont(new Font("Microsoft Sans Serif", 10f), true);
    var _blackBrush = new PdfSolidBrush(System.Drawing.Color.Black);
    PdfStringFormat format = new PdfStringFormat();
    format.Alignment = PdfTextAlignment.Center;
    format.WordWrap = PdfWordWrapType.Word;
    string title = "This text is too long and doesn't match in one line of the page XXX-3 111111111 22222 33333 44444 55555 66666 77777 88888 99999 000000";
    //Draw title
    header.Graphics.DrawString(title, _headerFont, _blackBrush, new RectangleF(0, 0, header.Width, header.Height), format);           
    e.PdfDocumentTemplate.Top = header;
}
