In this post, I will explain how to export gridview to Excel in Asp.Net?
There often is a need in a project's reporting module to show records of a GridView in an Excel sheet. In ASP.Net we can easily export data of gridview data to an excel file. I will explain how to export data of gridview to an Excel sheet with an example.In this example, we will bind gridview on the page load event and will export it to excel on "Export to Excel" button click.
ASPX Page Code(HTML Code)
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="ExportToExcel.aspx.vb" Inherits="ExportToExcel" %>
<!DOCTYPE html>
<html lang="">
<head runat="server">
<title>Gridview Export to Excel in ASP.Net</title>
<style>
body {
font-family: Georgia;
font-size: small;
}
.GridViewStyle {
border-right: 2px solid #A7A6AA;
border-bottom: 2px solid #A7A6AA;
border-left: 2px solid white;
border-top: 2px solid white;
padding: 4px;
}
.GridViewStyle a {
}
.GridViewHeaderStyle th {
border-left: 1px solid #EBE9ED;
border-right: 1px solid #EBE9ED;
}
.GridViewHeaderStyle {
font-weight: bold;
}
.GridViewFooterStyle {
font-weight: bold;
}
.GridViewRowStyle {
}
.GridViewAlternatingRowStyle {
}
.GridViewRowStyle td, .GridViewAlternatingRowStyle td {
border: 1px solid #EBE9ED;
}
.GridViewSelectedRowStyle {
font-weight: bold;
}
.GridViewPagerStyle {
}
.GridViewPagerStyle table /* to center the paging links*/ {
margin: 0 auto 0 auto;
}
</style>
</head>
<body>
<form id="form1" runat="server" style="vertical-align: top;">
<h2>Gridview Export to Excel in ASP.Net</h2>
