A practical example of a WCF service for inserting , Deleting and Displaying Data using a WCF Service in ASP.NET


WCF is more popular now a days and for beginners, I will show you a practical example of a WCF service for inserting, deleting and displaying data using ASP.NET.

Basically, this tip will demonstrate with example the following:

  • Step by step procedure/example to create WCF service
  • How to consume/access WCF service 
  • How to Use Proxy class
  • How to get data from WCF
  • How to bind/Load/Fill gridview from SQL Server database using WCF service
  • How to perform insert, edit, update and delete operation on gridview using WCF service

Using the Code

For inserting data into a database using a WCF service in ASP.NET, we have to do the following steps:

  • Create a WCF service
  • Create a Web based application

Part 1: Create a WCF Service

Open Visual Studio 2010/2012.

Step 1: Open Visual Studio -> Go to File menu -> New -> Project -->  Select the new Empty Solution and give name WCFProject.

Step 2: Then add new Class Library Project and give name SaleClassLibrary.

Step 3: Then add reference of System.ServiceModel and System.Runtime.Serialization into that project.

Step 4: Then add new Interface ISaleService.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
using System.Collections.Generic;
using System.Runtime.Serialization;
using System.ServiceModel;

    interface ISaleService
         bool InsertCustomer(Customer obj);

        List<Customer> GetAllCustomer();

        bool DeleteCustomer(int Cid);

        bool UpdateCustomer(Customer obj);     

   public class Customer
        public int CustomerID;
        public string CustomerName;        
        public string Address;
        public string EmailId;

Step 5: And write the following code in the SaleService.cs file:

SaleService.cs page:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;

public class SaleService : ISaleService
        public bool InsertCustomer(Customer obj)
            return true;

        public List<Customer> GetAllCustomer()
            return cutomerList;

        public bool DeleteCustomer(int Cid)
            var item = cutomerList.First(x => x.CustomerID == Cid);

            return true;

        public bool UpdateCustomer(Customer obj)
            var list = cutomerList;
            cutomerList.Where(p => p.CustomerID == 
            obj.CustomerID).Update(p => p.CustomerName = obj.CustomerName);
            return true;

      public static  List<Customer> cutomerList = new List<Customer>()
        new Customer {CustomerID = 1, CustomerName="Sujeet", 
        Address="Pune", EmailId="" },
        new Customer {CustomerID = 2, CustomerName="Rahul", 
        Address="Pune", EmailId="" },
        new Customer {CustomerID = 3, CustomerName="Mayur", 
        Address="Pune", EmailId=""}
 public static class LinqUpdates
        public static void Update<T>(this IEnumerable<T> source, Action<T> action)
            foreach (var item in source)

Step 6: Build your Class library.

Step 7: Add New Empty ASP.NET Project into that Solution, give name SaleServiceHost.

Image 2

Step 8: Add reference of Classlibrary Project to that SaleServiceHost ASP.NET project.

Step 9: Add new item WCF Service in that SaleServiceHost ASP.NET project and give name SaleService.

Image 3

Step 10: Right click on that SaleService.svc and select view Markup:

Image 4

Change the Service Name from that markup:

<%@ ServiceHost Language="C#" Debug="true" 
Service="SaleClassLibrary.SaleService"  %>

Step 11: And build the solution and SaleServiceHost set as startup project and SaleService.svc set as startup page.

Image 5

In this way, your WCF service builds successfully.

Part 2: Create a Web Based Application (Client)

Now, create your client application in your system:

Image 6

<html xmlns="">
<head runat="server">
    <form id="form1" runat="server">
        Welcome to Sale Service</h2><table class="style1">
                <td style="text-align: right">
                    Enter name</td>
                    <asp:TextBox ID="TextBox1" 
                <td class="style2">
                    <asp:TextBox ID="TextBox2" 
                <td class="style2">
                    Email ID</td>
                    <asp:TextBox ID="TextBox3" 
                <td class="style2">
                    <asp:Button ID="Button1" runat="server" 
                    onclick="Button1_Click" Text="Save" />
        <asp:GridView ID="GridView1" runat="server" 
        AllowPaging="True"  DataKeyNames="CustomerID,CustomerName"
            AllowSorting="True" AutoGenerateDeleteButton="True" 
        <asp:Label ID="Label1" runat="server" 
using SaleService;
  1. Create a Website.
  2. Add Service Reference http://localhost:53544/SaleService.svc?wsdl to a Web Application.
  3. Select your Website.
  4. Right click on it, add Service Reference, then enter your Service URL and click Go.
  5. Give the name for your service SaleService -> OK.
  6. Then automatically a proxy will be created in your client system.
  7. Write the following code in your source code:
  8. Add your service reference on the top.
  9. Then create an object for Service Reference and use that object to call the methods from your service.
  10. Write the following code in your aspx.cs file.
Default.aspx.cs page:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Collections.Generic;
using ServiceReference1;

public partial class _Default : System.Web.UI.Page
    SaleService.SaleServiceClient proxy;
        protected void Page_Load(object sender, EventArgs e)
            if (!IsPostBack)
                 proxy=new SaleService.SaleServiceClient();

        protected void Button1_Click(object sender, EventArgs e)
            proxy = new SaleService.SaleServiceClient();
            SaleService.Customer objcust = 
            new SaleService.Customer() { CustomerID=5, CustomerName=TextBox1.Text,
            Address=TextBox2.Text,EmailId=TextBox3.Text  };


            GridView1.DataSource = proxy.GetAllCustomer();
            Label1.Text = "Record Saved Successfully";

        protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
            int userid = Convert.ToInt32(GridView1.DataKeys
            proxy = new SaleService.SaleServiceClient();

            bool check = proxy.DeleteCustomer(userid);
              Label1.Text = "Record Deleted Successfully";
              GridView1.DataSource = proxy.GetAllCustomer();

By using this, you have successfully inserted data in the database and you have also shown this in the gridview.
