使用MVP填充Combobox和DataGridView

Question

如何使用MVP（Model-View-Presenter）填充ComboBox和DataGridView。其實我有這樣的事情：

視圖的基類：

public interface IView 
{ 
    event EventHandler Initialize; 
    event EventHandler Load; 
} 

主講基類：

public class Presenter<TView> where TView : class, IView 
{ 
    private TView view; 
    public TView View { get { return view; } private set { view = value; } } 

    public Presenter(TView view) 
    { 
     if (view == null) 
      throw new ArgumentNullException("view"); 

     View = view; 
     View.Initialize += OnViewInitialize; 
     View.Load += OnViewLoad; 
    } 

    protected virtual void OnViewInitialize(object sender, EventArgs e) { } 

    protected virtual void OnViewLoad(object sender, EventArgs e) { } 
} 

的具體看法：

public interface IAdministrarUsuariosView : IView 
{ 

    string NombreUsuarioABuscar {get; set;} 

    List<Perfil> ListaPerfiles {get; set;} 

    event EventHandler BuscarUsuarioPorNombre; 
    event EventHandler BuscarUsuarioPorPerfil; 
} 

我不知道如何填充組合框和Datagridview！

PD：由於喬希用於查看和演示基類（MVP Base Class）

致謝代碼!!

Answer 1

您需要創建一個屬性，您將使用該屬性爲ComboBox和DropdownList設置數據源。

只給你一個例子（你需要提高這個代碼，但它表明你如何能做到這一點的方式）

在您

查看：

//this is just a template to simulate a datasource item 
public class TestItem 
{ 
    public int Id { get; set; } 
    public string Description { get; set; } 
} 

public interface IAdministrarUsuariosView : IView 
{ 

    string NombreUsuarioABuscar { get; set; } 

    // List<Perfil> ListaPerfiles { get; set; } 

    event EventHandler BuscarUsuarioPorNombre; 
    event EventHandler BuscarUsuarioPorPerfil; 
    List<TestItem> SetComboBox { set; } 
    List<TestItem> SetGridView { set; } 

} 

然後在具體的視圖（該imolements的IAdministrarUsuariosView在WinForm

public class YourView:IAdministrarUsuariosView 
{ 
    public string NombreUsuarioABuscar 
    { 
     get { throw new NotImplementedException(); } 
     set { throw new NotImplementedException(); } 
    } 

    public event EventHandler BuscarUsuarioPorNombre; 
    public event EventHandler BuscarUsuarioPorPerfil; 

    public List<TestItem> SetComboBox 
    { 
     set 
     { 
      ComboBox.DataSource = value; 
      //your need to specify value and text property 
      ComboBox.DataBind(); 
     } 
    } 

    public List<TestItem> SetGridView 
    { 
     set 
     { 
      GridView.DataSource = value; 
      //your need to specify value and text property 
      GridView.DataBind(); 

     } 
    } 
} 

那麼你的演講應該像下面的：

public class YourPresenter:Presenter<IAdministrarUsuariosView> 
{ 

    public YourPresenter(IAdministrarUsuariosView view) : base(view) 
    { 
    } 

    protected override void OnViewLoad(object sender, EventArgs e) 
    { 
     List<TestItem> listResult = GetListItem(); 
     this.View.SetComboBox = listResult; 
     this.View.SetGridView = listResult; 
    } 
}
