In this post, I explain you about how to edit the GridView Row Values in ASP.NET with Ajax. First, create a new project on Visual Studio. In ASP.NET write the following code:
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajax" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title> How to Edit the GridView Row Values in ASP.NET with Ajax </title>
<style type="text/css">
.modalBackground
{
background-color: black;
opacity: 0.7;
}
#grd
{
margin:25px;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:DropDownList></asp:DropDownList>
<h4>Details</h4>
<div>
<asp:GridView ID="grd" runat ="server" GridLines="Both" BorderColor="#4F81BD" BorderStyle="Solid"
BorderWidth="1px" Style="position: static" AutoGenerateColumns="false" > <Columns>
<asp:BoundField DataField="User_id" HeaderText="User ID" SortExpression="User_id" />
<asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" /> <asp:BoundField DataField="Email_Address" HeaderText="Email Address" SortExpression="Email_Address" />
<asp:BoundField DataField="Mobile" HeaderText="Mobile No" SortExpression="Mobile" />
<asp:TemplateField HeaderText="Edit">
<ItemTemplate>
<asp:LinkButton ID="lnkBtn" runat="server" OnClick="lnkbtn_Click">Edit</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<RowStyle BorderColor="Red" BorderWidth="2px"></RowStyle>
</asp:GridView>
</div>
<asp:Button ID="btnShow" Visible="true" runat="server" />
<ajax:ModalPopupExtender ID="ModalPopup" runat="server" TargetControlID="btnShow"

</ajax:ModalPopupExtender>
<div ID="PnlShow" runat="server" style="display: none;background-color:white;">
<span style="float: right; padding-right: 0px; margin: 0px;">
<asp:Button ID="btnClose" Text="X" runat ="server" />
</span>
<div style="margin:25px;">
<table >

<td colspan="2" >User Details</td>
