Silverlight {Binding Key} - 请刷新我的记忆?

Mat*_*tts 1 silverlight binding

我确信这很简单,但我到底在这里错过了什么?有人能告诉我关键字"Key"引用了Text="{Binding Key}"什么?我知道我之前已经了解过它,但我似乎无法记住.我理解数据绑定是如何工作的,只是坚持这个特定的问题.

 <DataTemplate x:Key="groupItemHeader">
            <Border Background="{StaticResource PhoneAccentBrush}"
                    Width="432" Height="62"
                    Margin="6" Padding="12,0,0,6">
                <TextBlock Text="{Binding Key}" 
                           Foreground="#FFFFFF" FontSize="26.667"
                           HorizontalAlignment="Left"
                           VerticalAlignment="Bottom"
                           FontFamily="{StaticResource PhoneFontFamilySemiBold}"/>
                <Border.Projection>
                    <PlaneProjection RotationX="-60"/>
                </Border.Projection>
            </Border>
        </DataTemplate>

{Binding Key}是简写{Binding Path=Key}.这将返回Key当前属性的值DataContext.
