Question

我需要将dx-data-grid（devExpress网格）导出到pdf文档。有一个解决方案可用于将数据导出到excel，但是如何将其导出为pdf？

Answer 1

目前dxDataGrid上不允许这样做，请回答DX支持：

目前，dxDataGrid不提供导出到PDF功能。我们知道这个限制，这个功能在我们的TO-DO列表中。但是，我无法为您提供何时可以引入的确切日期。 https://www.devexpress.com/Support/Center/Question/Details/T458071/dxdatagrid-is-it-possible-to-export-data-to-pdf

但您可以在应用的服务器端生成自己的pdf文件。使用iTextSharp，本文将介绍如何执行此操作http://www.c-sharpcorner.com/UploadFile/f4f047/generating-pdf-file-using-C-Sharp/

using iTextSharp.text;  
using iTextSharp.text.pdf; 

protected void GeneratePDF(object sender, System.EventArgs e)  
{  
using(System.IO.MemoryStream memoryStream = new System.IO.MemoryStream())   
{  
    Document document = new Document(PageSize.A4, 10, 10, 10, 10);  

    PdfWriter writer = PdfWriter.GetInstance(document, memoryStream);  
    document.Open();  

    Chunk chunk = new Chunk("This is from chunk. ");  
    document.Add(chunk);  

    Phrase phrase = new Phrase("This is from Phrase.");  
    document.Add(phrase);  

    Paragraph para = new Paragraph("This is from paragraph.");  
    document.Add(para);  

    string text = @ "you are successfully created PDF file.";  
    Paragraph paragraph = new Paragraph();  
    paragraph.SpacingBefore = 10;  
    paragraph.SpacingAfter = 10;  
    paragraph.Alignment = Element.ALIGN_LEFT;  
    paragraph.Font = FontFactory.GetFont(FontFactory.HELVETICA, 12f, BaseColor.GREEN);  
    paragraph.Add(text);  
    document.Add(paragraph);  

    document.Close();  
    byte[] bytes = memoryStream.ToArray();  
    memoryStream.Close();  
    Response.Clear();  
    Response.ContentType = "application/pdf";  

    string pdfName = "User";  
    Response.AddHeader("Content-Disposition", "attachment; filename=" + pdfName + ".pdf");  
    Response.ContentType = "application/pdf";  
    Response.Buffer = true;  
    Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);  
    Response.BinaryWrite(bytes);  
    Response.End();  
    Response.Close();  
}  
}

然后将其转移到您的客户端 How to download a file to client from server?
