DataList to PDFエクスポート

Question

私は、タグクラウド（データリストを使って赤と緑のタグ）を表示するASCXコントロールを持っています。このデータリストをPDFファイルにエクスポートして、タグのサイズとその色を保存する方法はありますか？ご協力ありがとうございます

Answer 1

.NET用PDFライブラリを使用してください。最も良い例はおそらくiTextです。 書籍iText in Actionも投資価値があり、すぐにiText .NET APIを使用して稼働させることができます。

HTMLフラグメントをPDFに変換するのではなく、ASCX/HTMLバージョンに加えて、タグクラウドのPDFバージョンを作成します。

Response.ContentType = "application/pdf"; 
    Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf"); 
    Response.Cache.SetCacheability(HttpCacheability.NoCache); 
    StringWriter sw = new StringWriter(); 
    HtmlTextWriter hw = new HtmlTextWriter(sw); 
    datalist1.RenderControl(hw); 
    StringReader sr = new StringReader(sw.ToString()); 
    Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f); 
    HTMLWorker htmlparser = new HTMLWorker(pdfDoc); 
    PdfWriter.GetInstance(pdfDoc, Response.OutputStream); 
    pdfDoc.Open(); 
    htmlparser.Parse(sr); 
    pdfDoc.Close(); 
    Response.Write(pdfDoc); 
    Response.End();
