In simple terms "It enables the value to uniquely identify the data-bound instance of a grid view that generates the client id".
Step 1: Create a new "ASP.NET Web Application", as in:
Step 2: The complete code WebForm1.aspx looks like this:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="ClientIDRowSuffixApp.WebForm1" %>

<body>
<form id="form1" runat="server">

<div>
<table>
<tr>
<td colspan="2">
<asp:Label ID="Label1" runat="server" Text="ClientIDRowSuffix Property " Font-Bold="true"
Font-Size="Large" Font-Names="Verdana" ForeColor="Maroon"></asp:Label>
</td>
</tr>
<tr>
<td colspan="2" align="center">
<asp:Button ID="Button1" runat="server" Text="Select Data" Font-Names="Verdana" Width="213px"
BackColor="Orange" Font-Bold="True" OnClick="Button1_Click" />
</td>
</tr>
<tr>
<td colspan="2" align="center">
<br />
<asp:GridView ID="GridView1" runat="server" BackColor="LightGoldenrodYellow" BorderColor="Tan"
BorderWidth="1px" CellPadding="2" EnableModelValidation="True" ForeColor="Black"
GridLines="None" AutoGenerateColumns="False" ClientIDRowSuffix="EmpId">
<AlternatingRowStyle BackColor="PaleGoldenrod"></AlternatingRowStyle>
<FooterStyle BackColor="Tan"></FooterStyle>
<HeaderStyle BackColor="Tan" Font-Bold="True"></HeaderStyle>
<PagerStyle HorizontalAlign="Center" BackColor="PaleGoldenrod" ForeColor="DarkSlateBlue">
</PagerStyle>
<SelectedRowStyle BackColor="DarkSlateBlue" ForeColor="GhostWhite"></SelectedRowStyle>
<Columns>
<asp:BoundField DataField="EmpId" HeaderText="Emp Id" />
<asp:BoundField DataField="FirstName" HeaderText="First Name" />
<asp:BoundField DataField="LastName" HeaderText="Last Name" />
<asp:BoundField DataField="Age" HeaderText="Age" />
</Columns>
</asp:GridView>
</td>
</tr>
</table>
</div>
</center>
</form>
</body>
</html>
Step 3: The complete code WebForm1.aspx.cs looks like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;namespace ClientIDRowSuffixApp
{
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
GridView1.DataSource = objEntities.Employee.ToList();
GridView1.DataBind();
}
#region Instance VariablesCompanyEntities1 objEntities = new CompanyEntities1();
#endregion
}
}
Step 4: The output of application looks like this:
Step 5: The data selected output of the application looks like this:
