WPF自定義控件本地地產結合

Question

我有named- RoomAndPersonsAccommodationItem和內部自定義控件我有產權房：

public static readonly DependencyProperty roomProperty = 
DependencyProperty.Register("Room", typeof(RoomData), 
typeof(RoomAndPersonsAccommodationItem), new FrameworkPropertyMetadata(null)); 

     public RoomData RoomProperty 
     { 
      get { return GetValue(roomProperty) as RoomData; } 
      set { SetValue(roomProperty, value); } 
     } 


     private RoomData room = null; 
public RoomData Room 
     { 
      get { return room; } 
      set { room = value; } 
     } 

RoomAndPersonsAccommodationItem設置喜歡的DataTemplate上的ListView：

<ListView Name="RoomsListView" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" > 
        <ListView.ItemsPanel> 
         <ItemsPanelTemplate> 
          <StackPanel Orientation="Horizontal"></StackPanel> 
         </ItemsPanelTemplate> 
        </ListView.ItemsPanel> 
        <ListView.ItemTemplate> 
         <DataTemplate> 
          <Controls:RoomAndPersonsAccommodationItem Room="{Binding Path=., Mode=TwoWay}" HorizontalAlignment="Stretch" 
                     VerticalAlignment="Stretch" /> 
         </DataTemplate> 
        </ListView.ItemTemplate> 

       </ListView> 

在課堂上哪裏是以上ListView- RoomsListView我有這樣的代碼：

RoomsListView.ItemsSource = reservation.Rooms; 
//reservation.Rooms is List<RoomData> 

p這裏是：

<Controls:RoomAndPersonsAccommodationItem Room="{Binding Path=., Mode=TwoWay}" HorizontalAlignment="Stretch" 
                      VerticalAlignment="Stretch" /> 

我想從ListView上的ItemSource綁定Room屬性到房間對象，但我收到null。 有誰知道我錯在哪裏？也許在這裏：Room =「{Binding Path =。，Mode = TwoWay}」或DependencyProperty聲明？

感謝 馬丁

UPDATE：

還不行......結果始終爲空。我嘗試了很多選項來綁定Tag或DataContext，但沒有任何反應。我想這個問題不在DependencyProperty中。它是介於結合我的事情...... 這再次驗證碼：

private ReservationData reservation = null; 
//Methods 
private void fillForms() 
     { 
      //Logic 
        RoomsListView.ItemsSource = reservation.Rooms; 
      //Logic 
     } 

這是DataTemplate中ListView控件：

<ListView Name="RoomsListView" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" > 
        <ListView.ItemsPanel> 
         <ItemsPanelTemplate> 
          <StackPanel Orientation="Horizontal"></StackPanel> 
         </ItemsPanelTemplate> 
        </ListView.ItemsPanel> 
        <ListView.ItemTemplate> 
         <DataTemplate> 
          <Controls:RoomAndPersonsAccommodationItem 
           Room="{Binding}" 
           HorizontalAlignment="Stretch" VerticalAlignment="Stretch" /> 
         </DataTemplate> 
        </ListView.ItemTemplate> 

       </ListView> 

在RoomAndPersonsAccommodationItem

而且DependencyProperty的：

public static readonly DependencyProperty RoomProperty = 
    DependencyProperty.Register(
     "Room", typeof(RoomData), typeof(RoomAndPersonsAccommodationItem), 
     new FrameworkPropertyMetadata(null)); 

     public RoomData Room 
     { 
      get { return (RoomData)GetValue(RoomProperty); } 
      set { 
       SetValue(RoomProperty, value); } 
     } 

UPDATE 2

已解決 上面的來源是正確的。錯誤的結果來自於我在構造函數完成之前檢查了房間屬性。當我檢查構造函數後的結果一切正常！謝謝！

Answer 1

試試這個，一個特性，一個依賴屬性此屬性：

public static readonly DependencyProperty RoomProperty = 
    DependencyProperty.Register(
     "Room", typeof(RoomData), typeof(RoomAndPersonsAccommodationItem), 
     new FrameworkPropertyMetadata(null)); 

public RoomData Room 
{ 
    get { return (RoomData)GetValue(RoomProperty); } 
    set { SetValue(RoomProperty, value); } 
} 

您還可以刪除從綁定的「路徑」，這是沒有必要的。
