ASP.NET Export GridView to Excel

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 :
