In this post, I’ll share a simple class which you can use to export your ASP.NET GridView to Excel Sheet file. You have to pass your ASP.NET GridView control name (Id of GridView) and file name with which you wish to export the excel sheet file.

ASP.NET Export GridView to Excel class :


public void GridViewToExcelSheet(GridView dataGrid, String fileName)
{
try
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename="+fileName+System.DateTime.Now.ToString()+".xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
using (StringWriter stringWriter = new StringWriter())
{
HtmlTextWriter htmlTextWriter = new HtmlTextWriter(stringWriter);
dataGrid.RenderControl(htmlTextWriter);
Response.Output.Write(stringWriter.ToString());
Response.Flush();
Response.End();
}
}
catch (Exception ex)
{
String error = ex.Message.ToString();
}
}

public override void VerifyRenderingInServerForm(Control control)
{
/* Verifies that all the controls is rendered */
}

My GridView :

Exported Excel Sheet of GridView :

Usage :

Let’s see how we can use the above class in our .aspx.cs file.

My Design page – .ASPX Page :


<%@ Page Language="C#" AutoEventWireup="true" CodeFile="GridViewToExcel.aspx.cs" Inherits="GridViewToExcel" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<body>
<form id="form1" runat="server">
<div>
<asp:GridView runat="server" ID="myDataGrid" BackColor="White" BorderColor="#999999"

<asp:Button runat="server" Text="Export" ID="btnExport" OnClick="btnExport_Click" />
</div>
</form>
</body>
</html>

Code file – .ASPX.CS page (File name : GridViewToExcel.aspx.cs)

Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
using (StringWriter stringWriter = new StringWriter())
{
HtmlTextWriter htmlTextWriter = new HtmlTextWriter(stringWriter);
dataGrid.RenderControl(htmlTextWriter);
Response.Output.Write(stringWriter.ToString());
Response.Flush();
Response.End();
}
}
catch (Exception ex)
{
String error = ex.Message.ToString();
}
}

public override void VerifyRenderingInServerForm(Control control)
{
/* Verifies that all the controls is rendered */
}

protected void btnExport_Click(object sender, EventArgs e)
{
GridViewToExcelSheet(myDataGrid, "myGridExcelFile");
}

}
