How we can export Grid View Data to a Text File in asp.net c# ? 

In this article I am going to explain how we can export our Grid View data in a text file.

Below is my Data Table in design mode from which I will show data in Grid View.

Script of my Table is:

CREATE TABLE [dbo].[Employee](
          [Emp_ID] [int] IDENTITY(1,1) NOT NULL,
          [Name] [varchar](50) NULL,
          [Designation] [varchar](50) NULL,
          [City] [varchar](50) NULL,
          [State] [varchar](50) NULL,
          [Country] [varchar](50) NULL,
   CONSTRAINT [PK_Employee] PRIMARY KEY CLUSTERED
  (
          [Emp_ID] ASC
  )WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF,
  IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
  ) ON [PRIMARY] 

GO

 

Data in my Table:

Below is my aspx code

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

<body>
    <form id="form1" runat="server">
    <div>
        <table style="border: solid 15px blue; width: 100%; vertical-align: central;">
            <tr>
                <td style="padding-left: 50px; padding-top: 20px; padding-bottom: 20px; background-color: skyblue;
                    font-size: 20pt; color: orangered;">

                </td>
            </tr>
            <tr>
                <td style="text-align: left; padding-left: 50px; border: solid 1px red;">
                    <asp:GridView ID="GridViewEmployee" runat="server" AutoGenerateColumns="False" Width="90%"
                        BackColor="White" BorderColor="#3366CC" BorderStyle="None" BorderWidth="1px"
                        CellPadding="4" GridLines="Both">
                        <Columns>
                            <asp:BoundField DataField="Name" HeaderText="Employee Name" />
                            <asp:BoundField DataField="Designation" HeaderText="Designation" />
                            <asp:BoundField DataField="City" HeaderText="City" />
                            <asp:BoundField DataField="State" HeaderText="State" />
                            <asp:BoundField DataField="Country" HeaderText="Country" />
                        </Columns>
                        <FooterStyle BackColor="#99CCCC" ForeColor="#003399" />
                        <HeaderStyle BackColor="#003399" Font-Bold="True" ForeColor="#CCCCFF" />
                        <PagerStyle BackColor="#99CCCC" ForeColor="#003399" HorizontalAlign="Left" />
                        <RowStyle BackColor="White" ForeColor="#003399" />
                        <SelectedRowStyle BackColor="#009999" Font-Bold="True" ForeColor="#CCFF99" />
                    </asp:GridView>
                </td>
            </tr>
            <tr>
                <td align="right">
                    <asp:Button ID="btnExport" Text="Export Grid View" OnClick="btnExport_Click" runat="server" />
                </td>
            </tr>
        </table>
    </div>
    </form>
</body>
</html>


Now my aspx.cs code is:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;
 
public partial class _Default : System.Web.UI.Page
{
    SqlDataAdapter da;
    DataSet ds = new DataSet();
    DataTable dt = new DataTable();
 
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
            this.BindGrid();
    }
 
    private void BindGrid()
    {
        SqlConnection con = new SqlConnection();
        ds = new DataSet();
        con.ConnectionString = @"Data Source=INDIA\MSSQLServer2k8; Initial Catalog=EmployeeManagement; Uid=sa; pwd=india;";
        SqlCommand cmd = new SqlCommand("SELECT * FROM EMPLOYEE", con);
 
        da = new SqlDataAdapter(cmd);
        da.Fill(ds);
        con.Open();
        cmd.ExecuteNonQuery();
        con.Close();
 
        if (ds.Tables[0].Rows.Count > 0)
        {
            GridViewEmployee.DataSource = ds.Tables[0];
            GridViewEmployee.DataBind();
        }
    }
 
    protected void btnExport_Click(object sender, EventArgs e)
    {
        string txtFile = string.Empty;
 
        //Adding Column Name In Text File.
        foreach (TableCell cell in GridViewEmployee.HeaderRow.Cells)
        {           
            txtFile += cell.Text + "\t\t";
        }
       
        txtFile += "\r\n";
 
        //Adding Data Column Values in Text File
        foreach (GridViewRow row in GridViewEmployee.Rows)
        {
            foreach (TableCell cell in row.Cells)
            {               
                txtFile += cell.Text + "\t\t";
            }            
            txtFile += "\r\n";
        }
        
        Response.Clear();
        Response.Buffer = true;
        Response.AddHeader("content-disposition", "attachment;filename=EmployeeData.txtFile");
        Response.Charset = "";
        Response.ContentType = "application/text";
        Response.Output.Write(txtFile);
        Response.Flush();
        Response.End();
    }
}

Now run your application:
