In this article I am going to explain with example how to Bind GridView and Export Gridview data to Ms Word file usingasp.net.

Bind and Export GridView data to Ms Word in asp.net

Implementation: Let's create an asp.net sample application to understand.

First of all create a Database e.g. "MyDataBase" and a also create a table under that DataBase in Sql Server and name it "EMPLOYEE" as shown in figure:

Note: EMP_ID column is set to Primary key and Identity specification is set to yes with Identity increment and Identity seed equal to 1. Insert some data in this table that you want to show in the Gridview.

Now in web.config file add the connection string under <configuration> tag :

</connectionStrings>

Note: Replace the Data Source and the Initial catalog as per your applicaton.

In the design page (.aspx) place a GridView control to bind with data and a Button control to Export the GridView data to MS word file.

Source Code:

<fieldset style="width:360px;">

<legend>Bind and Export GridView data to Ms Word in asp.net</legend>

<table>

<tr>

<td>

<asp:GridView ID="grEmp" runat="server" AllowPaging="True" AutoGenerateColumns="False"

GridLines="None" Width="100%" CellPadding="4" ForeColor="#333333">

<asp:BoundField DataField="EMP_NAME" HeaderText="Emp Name" />

<asp:BoundField DataField="DEPT" HeaderText="Department" />

<asp:BoundField DataField="SALARY" HeaderText="salary" />

<asp:BoundField DataField="EMAIL_ID" HeaderText="Email Id" />

</Columns>

</asp:GridView>

</td>

</tr>

<tr>

<td>

<asp:Button ID="btnExportToWord" runat="server" Text="Export To MS Word FIle"OnClick="btnExportToWord_Click" />

</td>

</tr>

</table>

</fieldset>

C#.Net Code to Bind and Export GridView data to Ms word file

First include the following namespaces

using System.Data;

using System.Data.SqlClient;

using System.Configuration;

using System.Net;

using System.Net.Mail;

using System.Web.UI.HtmlControls;

using System.IO;

using System.Text;

Then write the code as:

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["conStr"].ConnectionString);

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

BindEmpGrid();

}

public override void VerifyRenderingInServerForm(Control control)

{

//It solves the error "Control 'GridView1' of type 'GridView' must be placed inside a form tag with runat=server."

}

protected void BindEmpGrid()

{

SqlCommand cmd = new SqlCommand("select * from EMPLOYEE", con);

DataTable dt = new DataTable();

SqlDataAdapter adp = new SqlDataAdapter(cmd);

adp.Fill(dt);

grEmp.DataSource = dt;

grEmp.DataBind();

}

protected void btnExportToWord_Click(object sender, EventArgs e)

{

try

{

Response.ClearContent();

Response.AddHeader("content-disposition", "attachment;filename=MyWordFile.doc");

Response.Cache.SetCacheability(HttpCacheability.NoCache);

Response.Buffer = true;

Response.Charset = "";

Response.ContentType = "application/vnd.word";

StringWriter strWrite = new System.IO.StringWriter();

HtmlTextWriter htmWrite = new HtmlTextWriter(strWrite);

HtmlForm htmfrm = new HtmlForm();

grEmp.Parent.Controls.Add(htmfrm);

grEmp.AllowPaging = false;

htmfrm.Attributes["runat"] = "server";

htmfrm.Controls.Add(grEmp);

htmfrm.RenderControl(htmWrite);

Response.Write(strWrite.ToString());

Response.Flush();

Response.End();

}

catch (Exception ex){}

}

VB.Net Code to Bind and Export GridView data to Ms word file

First import the following namespaces

Imports System.Data

Imports System.Data.SqlClient

Imports System.Configuration

Imports System.Net

Imports System.Net.Mail

Imports System.Web.UI.HtmlControls

Imports System.IO

Imports System.Text

Then write the code as:

Dim con As New SqlConnection(ConfigurationManager.ConnectionStrings("conStr").ConnectionString)

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load

If Not Page.IsPostBack Then

BindEmpGrid()

End If

End Sub

Public Overrides Sub VerifyRenderingInServerForm(control As Control)

'It solves the error "Control 'GridView1' of type 'GridView' must be placed inside a form tag with runat=server."

End Sub

Protected Sub BindEmpGrid()

Dim cmd As New SqlCommand("select * from EMPLOYEE", con)

Dim dt As New DataTable()

Dim adp As New SqlDataAdapter(cmd)

adp.Fill(dt)

grEmp.DataSource = dt

grEmp.DataBind()

End Sub

Protected Sub btnExportToWord_Click(sender As Object, e As EventArgs)

Try

Response.ClearContent()

Response.AddHeader("content-disposition", "attachment;filename=MyWordFile.doc")

Response.Cache.SetCacheability(HttpCacheability.NoCache)

Response.Buffer = True

Response.Charset = ""

Response.ContentType = "application/vnd.word"

Dim strWrite As StringWriter = New System.IO.StringWriter()

Dim htmWrite As New HtmlTextWriter(strWrite)

Dim htmfrm As New HtmlForm()

grEmp.Parent.Controls.Add(htmfrm)

grEmp.AllowPaging = False

htmfrm.Attributes("runat") = "server"

htmfrm.Controls.Add(grEmp)

htmfrm.RenderControl(htmWrite)

Response.Write(strWrite.ToString())

Response.Flush()

Response.[End]()

Catch ex As Exception

End Try

End Sub

Notice that I have added an overriding function VerifyRenderingInServerForm in the code behind. This is to resolve the error “Control 'GridView1' of type 'GridView' must be placed inside a form tag with runat=server” that may occur on exporting GridView data to MS Excel file or MS Word or PDF or CSV (Comma separated value) file.

Exported gridview data to word file will look like as shown in figure:
