Insert ,update and delete in GridView using WCF Service in ASP.net ~ Dotnet in simpleway

Insert ,update and delete in GridView using WCF Service in ASP.net

Today we discus about the WCF services with Insert , Update and Delete with GridView in Asp .net

First we create WCF Services………….

Open new Website in Visual Studio 2010/2012

Select WCF Service (Visual C#)

Now add new item (entity Model)

Select Generate from database and click Next button:-

New create new connection with database(Sql Server 2005/2008)

input server name

use Sql Server authentication

option if user name and password are available orther wise select

Use windows authentication

Select or enter a database name:

enter database name

now click ok button. now click next button

now select table name:-

now click on finish.

we have one interface and one class name (IService and Service )

Code for IService Interface:-

using System;

using System.Collections.Generic;

using System.ComponentModel.DataAnnotations;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

[ServiceContract]

public interface IService

{

[OperationContract]

[FaultContract(typeof(OverflowException))]

[FaultContract(typeof(FormatException))]

[FaultContract(typeof(DivideByZeroException))]

List<userdetail> GetData();

[OperationContract]

string insertData(userDetails user);

[OperationContract]

string UpdateData(userDetails user);

[OperationContract]

string DeleteData(userDetails user);

}

[DataContract]

public class userDetails

{

int mid;

string mname;

int mage;

string memailid;

string mpass;

string mph;

[DataMember(Order=1)]

public int id

{

get { return mid; }

set { mid = value; }

}

[DataMember(Order = 2)]

[DataType(DataType.Text)]

public string name

{

get{return mname;}

set { mname = value; }

}

[DataMember(Order = 3)]

public int age

{

get { return mage; }

set { mage = value; }

}

[DataMember(Order = 4)]

[DataType(DataType.EmailAddress)]

public string emailid

{

get { return memailid; }

set { memailid = value; }

}

[DataMember(Order = 5)]

public string pass

{

get { return mpass; }

set { mpass =value ;}

}

[DataMember(Order = 6)]

public string ph

{

get { return mph; }

set { mph = value; }

}

Code for Service Class that implement IService Interface:-

using System;

using System.Collections.Generic;

using System.Data;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

public class Service : IService

{

testEntities te = new testEntities();

string msg = string.Empty;

public List<userdetail> GetData()

{

List<userDetails> dt = new List<userDetails>();

userDetails ud = new userDetails();

var v = te.userdetails.ToList();

return v.ToList();

}

public string insertData(userDetails user)

{

try

{

userdetail ud = new userdetail();

ud.name = user.name;

ud.age = user.age;

ud.emailid = user.emailid;

ud.ph = user.ph;

te.userdetails.Add(ud);

te.SaveChanges();

msg = "Data added successfully";

return msg;

}

catch (Exception)

{

return "Some Error occured ! ... Please Contanct Program vendor";

}

public string UpdateData(userDetails user)

{

try

{

var v = te.userdetails.FirstOrDefault(m => m.id == user.id);

if (v != null)

{

v.name = user.name;

v.age = user.age;

v.emailid = user.emailid;

v.ph = user.ph;

te.SaveChanges();

msg ="Data Updated successfully";

}

return msg;

}

catch (Exception)

{

return "Some Error occured ! ... Please Contanct Program vendor";

}

public string DeleteData(userDetails user)

{

try

{

var v = te.userdetails.FirstOrDefault(m => m.id == user.id);

if (v != null)

{

te.userdetails.Remove(v);

te.SaveChanges();

msg = "Data Deleted Successfully";

}

return msg;

}

catch (Exception ex)

{

return ex.Message;

}

}

code for Web.config file

<?xml version="1.0"?>

</configSections>

</appSettings>

<system.web>

</assemblies>

</buildProviders>

</compilation>

</system.web>

<system.serviceModel>

</service>

</services>

</behavior>

</serviceBehaviors>

</behaviors>

</protocolMapping>

</system.serviceModel>

<system.webServer>

<!--

To browse web app root directory during debugging, set the value below to true.

Set to false before deployment to avoid disclosing web app folder information.

-->

</system.webServer>

</connectionStrings>

</entityFramework>

</configuration>

now run the service.svc file from Solution Explorer....

Now Right click on Service.svc

and copy the url

http://localhost:2752/Service.svc

Now create a new website …..

Add service reference and paste url in address: and click go button

And add service name in Namespace

Then click ok button.

Now design the aspx page

Code for Aspx:-

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html>

.auto-style1

{

width: 100%;

}

</style>
