I will explain how to export data from
gridview to pdf in asp.net using c#.
I created a database with table name
EmployeeInfo as shown.
USE

00:13:02 ******/
SET

ON
GO
SET
QUOTED_IDENTIFIER
ON
GO
CREATE
TABLE
[dbo].[EmployeeInfo](
[EmpId]
[nvarchar](50)
NOT
NULL,
[EmpName]
[nvarchar](50)
NOT
NULL,
[EmpAddress]
[nvarchar](50)

GO
In
Default.aspx I am adding GridView and ImageButton as Shown.
<%@
Page
Language="C#"
AutoEventWireup="true"
CodeBehind="Default.aspx.cs"
Inherits="file_conversion._Default"
%>
<!DOCTYPE

<asp:GridView

<Columns>
<asp:BoundField

<asp:BoundField
DataField="EmpName"

<asp:BoundField

<asp:BoundField

</Columns>
</asp:GridView>
<asp:ImageButton

runat="server"
ImageUrl="Scripts/download.jpg"
ToolTip
="Click
To Export PDF Format"
Width="32px"
Height="32px"
OnClick="btnPDF_Click"
/>
</form>
</body>
</html>
Now
I am writing the logic in Default.aspx.cs to export gridview data in
to pdf format as shown.
using
System;
using
System.Configuration;
using
System.Data;
using
System.IO;
using
System.Linq;
using
System.Web;
using
System.Web.Security;
using
System.Web.UI;
using
System.Web.UI.HtmlControls;
using
iTextSharp.text;
using
iTextSharp.text.pdf;
using
iTextSharp.text.html.simpleparser;
using
System.Data.SqlClient;
namespace
file_conversion
{
public
partial
class
_Default
: System.Web.UI.Page
{
protected
void
Page_Load(object
sender, EventArgs
e)
{
if
(!IsPostBack)
{
BindGridData();
}
}
private
void
BindGridData()
{
try
{
using
(SqlConnection
con = new
SqlConnection(ConfigurationManager.ConnectionStrings["Connstring"].ConnectionString))
{
SqlCommand
command = new
SqlCommand("SELECT
* from EmployeeInfo",
con);
SqlDataAdapter
da = new
SqlDataAdapter(command);
DataTable
dt = new
DataTable();
da.Fill(dt);
gridview.DataSource
= dt;
gridview.DataBind();
}
}
catch
(Exception
ex)
{
}
}
protected
void
btnPDF_Click(object
sender, ImageClickEventArgs
e)
{
Response.ContentType
= "application/pdf";
Response.AddHeader("content-disposition",
"attachment;filename=File.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter
sw = new
StringWriter();
HtmlTextWriter
htw = new
HtmlTextWriter(sw);
HtmlForm
hfrm = new
HtmlForm();
gridview.Parent.Controls.Add(hfrm);
hfrm.Attributes["runat"]
= "server";
hfrm.Controls.Add(gridview);
hfrm.RenderControl(htw);
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();
}
}
}
In
web.config I am adding the ConnectionString
<connectionStrings>
<add
name="Connstring"
connectionString="Data
Source=DotNetSharePoint;Database=Chinnu;User
Id=sa;Password=password123;"
providerName="System.Data.SqlClient"
/>
</connectionStrings>
Now
Press F5.
