please use below code for web application protected void ExportToExcel(object sender, EventArgs e) { Response.Clear(); Response.Buffer = true ; Response.AddHeader( "content-disposition" , "attachment;filename=GridViewExport.xls" ); Response.Charset = "" ; Response.ContentType = "application/vnd.ms-excel" ; using (StringWriter sw = new StringWriter()) { HtmlTextWriter hw = new HtmlTextWriter(sw); //To Export all pages GridView1.AllowPaging = false ; this .BindGrid(); GridView1.HeaderRow.BackColor = Color.White; foreach (TableCell cell in GridView1.HeaderRow.Cells) { cell.BackColor = GridView1.HeaderStyle.BackColor; } foreach (GridViewRow row in GridView1.Rows) { row.BackColor = Color.White; foreach (TableCell cell in row.Cells) { if (row.RowIndex % 2 == 0) { cell.BackColor = GridView1.AlternatingRowStyle.BackColor; } else { cell.BackColor = GridView1.RowStyle.BackColor; } cell.CssClass = "textmode" ; } } GridView1.RenderControl(hw); //style to format numbers to string string style = @ " .textmode { } " ; Response.Write(style); Response.Output.Write(sw.ToString()); Response.Flush(); Response.End(); } } public override void VerifyRenderingInServerForm(Control control) { /* Verifies that the control is rendered */ }

You just need to reference Microsoft.Office.Interop.Excel and replace transcationTableDataGridView with your dataGridview and thats it.

Hi I have added reference but still getting below error please let me know is there any mistake happen or add any reference thanks

Rajanikant Hawaldar · Answer

@Gangadhar, open the solution explorer window expand your project folder accordion. right click on the references element select "add reference" from the dropdown select the .NET tab and look for the object library called Microsoft.Office.Interop.Excel click ok. transcationTableDataGridView is grid control name given in @Sachin singh example. i think you have just copy pasted so you need add required references and use.
