Today, in this article let's play around with one of the interesting and most useful concepts in .NET 4.5.

Question: What are model binders?

In simple terms "It is a data binding system which is used to perform some common operations based on the data retrieved from a model class with strongly typed invocations".

Step 1: Create a new "ASP.Net Web Forms Application", as in:

Step 2: The complete code of webform1.aspx looks like this:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="ModelBindersSelectApp.WebForm1" %>

<!DOCTYPE html>

<html xmlns="">

<head id="Head1" runat="server">




    <form id="form1" runat="server">



            <asp:GridView ID="GridView1" runat="server" BackColor="LightGoldenrodYellow" ItemType="ModelBindersSelectApp.Employee"

                BorderColor="Tan" BorderWidth="1px" CellPadding="2" ForeColor="Black" GridLines="None"

                AutoGenerateColumns="false" SelectMethod="GetData">

                <AlternatingRowStyle BackColor="PaleGoldenrod"></AlternatingRowStyle>

                <FooterStyle BackColor="Tan"></FooterStyle>

                <HeaderStyle BackColor="Tan" Font-Bold="True"></HeaderStyle>

                <PagerStyle HorizontalAlign="Center" BackColor="PaleGoldenrod" ForeColor="DarkSlateBlue">


                <SelectedRowStyle BackColor="DarkSlateBlue" ForeColor="GhostWhite"></SelectedRowStyle>

                <SortedAscendingCellStyle BackColor="#FAFAE7"></SortedAscendingCellStyle>

                <SortedAscendingHeaderStyle BackColor="#DAC09E"></SortedAscendingHeaderStyle>

                <SortedDescendingCellStyle BackColor="#E1DB9C"></SortedDescendingCellStyle>

                <SortedDescendingHeaderStyle BackColor="#C2A47B"></SortedDescendingHeaderStyle>


                    <asp:TemplateField HeaderText="Id">


                            <asp:Label ID="lblId" runat="server" Text='<%# Item.Id %>'></asp:Label></ItemTemplate>


                    <asp:TemplateField HeaderText="First Name">


                            <asp:Label ID="lblFirstName" runat="server" Text='<%# Item.FirstName %>'></asp:Label></ItemTemplate>


                    <asp:TemplateField HeaderText="Last Name">


                            <asp:Label ID="lblLastName" runat="server" Text='<%# Item.LastName %>'></asp:Label></ItemTemplate>


                    <asp:TemplateField HeaderText="Age">


                            <asp:Label ID="lblAge" runat="server" Text='<%# Item.Age %>'></asp:Label></ItemTemplate>









Step 3: The complete code of 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 ModelBindersSelectApp


    public partial class WebForm1 : System.Web.UI.Page


        protected void Page_Load(object sender, EventArgs e)



        public IQueryable GetData()

        {return objEntities.Employee;


        #region Instance VariablesCompanyEntities objEntities = new CompanyEntities();




Step 4: The output of the application looks like this:
