標題可能聽起來令人費解,但忍受着我。內部ItemsControl中的對象的屬性如何綁定到外部ItemsControl中的對象的屬性?
我有包含住戶房間:
public class Room
{
public string Name { get; set; }
public List<Person> Occupants { get; set; }
public bool AreOccupantsEditable { get; set; }
}
public class Person
{
public string Name { get; set; }
}
這裏的客房數組:
<ResourceDictionary>
<x:Array x:Key="Rooms" Type="local:Room">
<local:Room Name="Happy Room" AreOccupantsEditable="True">
<local:Room.Occupants>
<local:Person Name="Mindy" />
</local:Room.Occupants>
</local:Room>
<local:Room Name="Sad Room" AreOccupantsEditable="True">
<local:Room.Occupants>
<local:Person Name="Bob" />
<local:Person Name="Jane" />
</local:Room.Occupants>
</local:Room>
<local:Room Name="Kill Room" AreOccupantsEditable="False">
<local:Room.Occupants>
<local:Person Name="Mork" />
<local:Person Name="Dave" />
<local:Person Name="Ryan" />
</local:Room.Occupants>
</local:Room>
</x:Array>
</ResourceDictionary>
這裏是一個ItemsControl在一個ItemsControl,顯示房間和他們的居住者:
<ItemsControl ItemsSource="{Binding Source={StaticResource Rooms}}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel>
<!-- room name -->
<TextBlock Text="{Binding Path=Name}" />
<ItemsControl ItemsSource="{Binding Path=Occupants}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<!-- occupant name -->
<TextBox Text="{Binding Path=Name}" Margin="20,0,0,0" IsEnabled="{Binding ???}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
沒有人提及房間,我如何綁定T的IsEnabled屬性extBox轉到Are a Room的人的AreOccupantsEditable屬性?
如果有幫助,下面是一個示例項目:http://dl.dropbox.com/u/4220513/ItemsControl-Binding.zip
我正在玩RelativeSource和AncestorType,但我無法得到它的工作。明天早上我會說這個。 – epalm
對,這正是我所需要的。謝謝 – epalm
