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:
- Now in web.config file add the connection string under <configuration> tag :
<add name="conStr" connectionString="Data Source=LocalServer;Initial
Catalog=MyDataBase;Integrated Security=True"/>
</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;">
<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">
<AlternatingRowStyle BackColor="White" ForeColor="#284775" />
<Columns>
<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>
<EditRowStyle BackColor="#999999" />
<FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
<RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
<SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
<SortedAscendingCellStyle BackColor="#E9E7E2" />
<SortedAscendingHeaderStyle BackColor="#506C8C" />
<SortedDescendingCellStyle BackColor="#FFFDF8" />
<SortedDescendingHeaderStyle BackColor="#6F8DAE" />
</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.
Note: To view complete article on
why this error occur and how to resolve that error, read my article “How to Solve Error Control 'GridView1' of type 'GridView' must be placed inside a form tag with runat=server”
- Exported gridview data to word file will look like as shown in figure:
