Then Build your solution

Section 2: Coding follow your functionality, we have login form with 2 textbox and 1 button

Open LoginDTO.cs in project MVPPatternInSharepoint.Contract

Paste this code as follows:

public class LoginDTO

    {

        #region Properties

        public string UserName { get; set; }

        public string Password { get; set; }

        #endregion

        #region Events

        public event EventHandler Login;

        #endregion

    }

The user interface as follows

In project MVPPatternInSharepoint.Presentation, open ILoginView.cs

Paste this code as follows:

public interface ILoginView

    {

        #region Properties

        string UserName { get; set; }

        string Password { get; set; }

        #endregion

        #region Events

        event EventHandler Login;

        #endregion

    }

            set

            {

                txtUserName.Text = value;

            }

        }

    }

}

Finish code in LoginUserControl.ascx.cs

Open LoginPresenter.cs like this

Open LoginController.cs, Add Reference to MVPPatternInSharepoint.Contract.dll and MVPPatternInSharepoint.Data.dll

Paste this code into public class LoginController

Source code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using MVPPatternInSharepoint.Contract.DTO;

using MVPPatternInSharepoint.Data.SPRepository;

namespace MVPPatternInSharepoint.Model.Controllers

{

    public class LoginController

    {

        private string _url;

        public LoginController(string url)

        {

            _url = url;

        }

        public void Login(LoginDTO loginDTO)

        {

           

        }

    }

}

Build your Solution

Go back MVPPatternInSharepoint.Presentation project, Open LoginPresenter.cs >>replace this code in public class LoginPresenter Like this

Source code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using MVPPatternInSharepoint.Presentation.IView;

using MVPPatternInSharepoint.Model.Controllers;

using MVPPatternInSharepoint.Contract.DTO;

namespace MVPPatternInSharepoint.Presentation.Presenter

{

    public class LoginPresenter

    {

        private ILoginView _view;

        private LoginController _loginController;

        public LoginPresenter(string url, ILoginView view)

        {

            _view = view;

            _loginController = new LoginController(url);

            _view.Login += new EventHandler(_view_Login);

        }

        void _view_Login(object sender, EventArgs e)

        {

            LoginDTO loginDTO = new LoginDTO();

            loginDTO.UserName = _view.UserName;

            loginDTO.Password = _view.Password;

            _loginController.Login(loginDTO);

        }

    }

}

Finish coding in MVPPatternInSharepoint.Presentation project. Build solution

Open project MVPPattern.Data >> add references to MVPPatternInSharepoint.Contract.dll

Declare namespace

using MVPPatternInSharepoint.Contract.DTO;

Paste this code into public class LoginRepository

        {

            string userName = loginDTO.UserName;

            string password = loginDTO.Password;

        }

    }

}

Finish coding in MVPPatternInSharepoint.Data project. In Login method, you can get UserName and Password to do something (Select, Insert ….). Build your solution

Go back MVPPatternInSharepoint.Model project, open LoginController.cs, paste this code into method Login

Build your solution. Finish coding in MVPPatternInSharepoint.Model project

Section 3: Add dll of Class Library into Package and deploy webpart

In MVPPatternInSharepoint.Web project double click to Package.package and click to Advanced

Click button Add >> Add Assembly from Project output

Source project choose “MVPPatternInSharepoint.Presentation” and click to “click here to add new item” button

   

Namespace is “MVPPatternInSharepoint.Presentation.IView”

Assembly is “MVPPatternInSharepoint.Presentation”

Continue !!!!

Click button Add >> Add Assembly from Project output.  Source project choose “MVPPatternInSharepoint.Contract” and click to “click here to add new item” button

   

Namespace is “MVPPatternInSharepoint.Contract.DTO”

Assembly is “MVPPatternInSharepoint.Contract”

Continue !!!!

Click button Add >> Add Assembly from Project output.  Source project choose “MVPPatternInSharepoint.Model” and click to “click here to add new item” button

Namespace is “MVPPatternInSharepoint.Model.Controllers”

Assembly is “MVPPatternInSharepoint.Model”

Continue !!!!

Click button Add >> Add Assembly from Project output.  Source project choose “MVPPatternInSharepoint.Data” and click to “click here to add new item” button

Namespace is “MVPPatternInSharepoint.Data.SPRepository”

Assembly is “MVPPatternInSharepoint.Data”

Continue !!!!

Click button Add >> Add Assembly from Project output.  Source project choose “MVPPatternInSharepoint.Common” and click to “click here to add new item” button

Namespace is “MVPPatternInSharepoint.Common”

Assembly is “MVPPatternInSharepoint.Common”

Build your solution

Deploy “MVPPatternInSharepoint.Web” project but we have error “The primary reference "MVPPatternInSharepoint.Presentation" could not be resolved because it has an indirect dependency on the .NET Framework assembly "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" which has a higher version "4.0.0.0" than the version "2.0.0.0" in the current target framework.

 “

I search on google I check Target Framework of MVPPatternInSharepoint.Web is 3.5

But Class Library have Target Framework, so we change it to 3.5

For MVPPatternInSharepoint.Common

We do it for MVPPatternInSharepoint.Contract, MVPPatternInSharepoint.Data, MVPPatternInSharepoint.Model, MVPPatternInSharepoint.Presentation

Then Build solution but we continue get error “Error       2              Assembly generation failed -- Referenced assembly 'MVPPatternInSharepoint.Presentation' does not have a strong name   MVPPatternInSharepoint.Web”

Reason is: Class library don’t have Strong name, we will create for them

For MVPPatternInSharepoint.Common

Right click to MVPPatternInSharepoint.Common >> Signing >> Check to Sign the assembly >> choose New

We do it for MVPPatternInSharepoint.Contract, MVPPatternInSharepoint.Data, MVPPatternInSharepoint.Model, MVPPatternInSharepoint.Presentation

Then Build solution again and get successful

Deploy project sharepoint “MVPPatternInSharepoint.Web”

Add Webpart to sharepoint page successful
