In this demo tutorial I will show you how to export data from gridview to pdf file.

Steps are as follows:

1. Create new web page.

2. Drag & drop gridview from toolbox & bind your database (don’t use enable sorting).

<asp:GridView ID="GridView2" runat="server">

        asp:GridView>

3. Drag & drop button.

  <asp:Button ID="Button1" runat="server" Text="Button"
onclick="Button1_Click" />

4. You need to download one dll file named iTextSharp.dll.

5. Now add reference of this downloaded dll.

6. Now go to code behind & some of the following codes.

using iTextSharp.text;

using iTextSharp.text.pdf;

using iTextSharp.text.html.simpleparser;

7. Now add following code in code behind.

public override void VerifyRenderingInServerForm(Control control)

{

/* Verifies that the control is rendered */

}

protected void Button1_Click(object sender, EventArgs e)

{

Response.ContentType = "application/pdf";

Response.AddHeader("content0disposition",

"attachment;filename=UserDetails.pdf");

Response.Cache.SetCacheability(HttpCacheability.NoCache);

StringWriter sw = new StringWriter();

HtmlTextWriter hw = new HtmlTextWriter(sw);

GridView1.AllowPaging = false;

GridView1.DataBind();

GridView1.RenderControl(hw);

GridView1.HeaderRow.Style.Add("width", "15%");

GridView1.HeaderRow.Style.Add("font-size", "10px");

GridView1.Style.Add("text-decoration", "none");

GridView1.Style.Add("font-family", "Arial, Helvetica, sans-serif");

GridView1.Style.Add("font-size", "8px");

StringReader sr = new StringReader(sw.ToString());

StreamReader reader = new StreamReader(new MemoryStream(Encoding.ASCII.Ge tBytes(sw.ToString())));

Document pdfDoc = new Document(PageSize.A2, 7f, 7f, 7f, 0f);

HTMLWorker htmlparser = new HTMLWorker(pdfDoc);

PdfWriter.GetInstance(pdfDoc, Response.OutputStream);

pdfDoc.Open();

htmlparser.Parse(reader);

pdfDoc.Close();

Response.Write(pdfDoc);

Response.End();

}

Now on button click , whole data from your gridview will be transferred in pdf file .
