Mr. 14F: ASP.NET 將網頁輸出PDF

ASP.NET PDF
將網頁物件輸出至PDF，以下使用Table為例。

1.Download the itextsharp.dll from Internet.
2.Reference of itextsharp.dll

3.use following references of itextsharp.dll

using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.html.simpleparser;

4.Now the whole code of tsPDF.aspx.cs page will be as follows:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Configuration;
using System.Data.SqlClient;
using System.IO;
using System.Web;
using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.html.simpleparser;  

public partial class Test_tsPDF : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        
    }

    public override void VerifyRenderingInServerForm(Control control)
    {
        //required to avoid the runtime error "  
        //Control 'GridView1' of type 'GridView' must be placed inside a form tag with runat=server."  
    }  

    private void ExportGridToPDF()
    {
        try
        {
            Response.ContentType = "application/pdf";
            Response.AddHeader("content-disposition", "attachment;filename=Vithal_Wadje.pdf");
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            StringWriter sw = new StringWriter();
            HtmlTextWriter hw = new HtmlTextWriter(sw);
            //GridView1.RenderControl(hw);
            Table1.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();
            GridView1.AllowPaging = true;
            GridView1.DataBind();
        }
        catch (Exception)
        {
            
            throw;
        }
        
    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        ExportGridToPDF();  
    }
}

5.Now the whole code of tsPDF.aspx page will be as follows:

<body>
    <form id="form1" runat="server">
    <div>
        <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
        <asp:GridView ID="GridView1" runat="server"></asp:GridView>
        <asp:Table ID="Table1" runat="server">
            <asp:TableRow>
                <asp:TableCell>Cell 1</asp:TableCell>
                <asp:TableCell>Cell 2</asp:TableCell>
                <asp:TableCell>Cell 3</asp:TableCell>
                <asp:TableCell>Cell 4</asp:TableCell>
                <asp:TableCell>Cell 5</asp:TableCell>
                <asp:TableCell>Cell 6</asp:TableCell>
            </asp:TableRow>
        </asp:Table>
    </div>
    </form>
</body>
