How to Export Gridview Data to Excel and Word Document

I have one gridview that has filled with user details now I need to export gridview data to word or excel document based on selection. To implement this functionality first we need to design aspx page like this



<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table>
<tr>
<td align="right">
<asp:ImageButton ID="btnExcel" runat="server" ImageUrl="~/ExcelImage.jpg"
onclick="btnExcel_Click" />
<asp:ImageButton ID="btnWord" runat="server" ImageUrl="~/WordImage.jpg"
onclick="btnWord_Click" />
</td>
</tr>
<tr>
<td>
<asp:GridView runat="server" ID="gvdetails" DataSourceID="dsdetails"  AllowPaging="true"AllowSorting="true" AutoGenerateColumns="false">
<RowStyle BackColor="#EFF3FB" />
<FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
<HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<AlternatingRowStyle BackColor="White" />
<Columns>
<asp:BoundField DataField="UserId" HeaderText="UserId" />
<asp:BoundField DataField="UserName" HeaderText="UserName" />
<asp:BoundField DataField="LastName" HeaderText="LastName" />
<asp:BoundField DataField="Location" HeaderText="Location" />
</Columns>
</asp:GridView>
</td>
</tr>
</table>
<asp:SqlDataSource ID="dsdetails" runat="server"ConnectionString="<%$ConnectionStrings:dbconnection %>"
SelectCommand="select * from UserInformation"/>
</div>
</form>
</body>
</html>

Here don’t forgot to set the connection string in web.config file here I am getting database connection from web.config file for that reason you need to set the connectionstring in web.config file like this 
<connectionStrings>
<add name="dbconnection" connectionString="Data Source=SureshDasari;Integrated Security=true;Initial Catalog=MySampleDB"/>
</connectionStrings>

Now in code behind add this reference:

using System.IO;
public override void VerifyRenderingInServerForm(Control control)
{
/* Verifies that the control is rendered */
}
/// <summary>
/// This event is used to export gridview data to word document
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void btnWord_Click(object sender, ImageClickEventArgs e)
{
gvdetails.AllowPaging = false;
gvdetails.DataBind();
Response.ClearContent();
Response.AddHeader("content-disposition"string.Format("attachment; filename={0}","Customers.doc"));
Response.Charset = "";
Response.ContentType = "application/ms-word";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gvdetails.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
}
/// <summary>
/// This Event is used to export gridview data to Excel
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void btnExcel_Click(object sender, ImageClickEventArgs e)
{
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition"string.Format("attachment; filename={0}""Customers.xls"));
Response.ContentType = "application/ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gvdetails.AllowPaging = false;
gvdetails.DataBind();
//Change the Header Row back to white color
gvdetails.HeaderRow.Style.Add("background-color""#FFFFFF");
//Applying stlye to gridview header cells
for (int i = 0; i < gvdetails.HeaderRow.Cells.Count; i++)
{
gvdetails.HeaderRow.Cells[i].Style.Add("background-color""#507CD1");
}
int j = 1;
//This loop is used to apply stlye to cells based on particular row
foreach (GridViewRow gvrow in gvdetails.Rows)
{
gvrow.BackColor = Color.White;
if (j <= gvdetails.Rows.Count)
{
if (j % 2 != 0)
{
for (int k = 0; k < gvrow.Cells.Count; k++)
{
gvrow.Cells[k].Style.Add("background-color""#EFF3FB");
}
}
}
j++;
}
gvdetails.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
}

I hope this might help you.
