绑定用户控件内LongListSelector当前项目 [英] Binding user control inside LongListSelector with current Item

问题描述

这是我在做什么。

UserControl.xaml

<Grid x:Name="LayoutRoot" Background="{StaticResource PhoneChromeBrush}">
    <phone:LongListSelector
        Name="MainList"
        ItemsSource="{Binding}">
        <phone:LongListSelector.ItemTemplate>
            <DataTemplate>
                <StackPanel>
                <views:PostView
                    DataContext="{Binding ElementName=MainList, Path=ItemsSource}">
                </views:PostView>
                </StackPanel>
            </DataPanel>

我希望我的后览内部控制与当前的ItemsSource元的性质的约束。但是，什么情况是，说我有设置的ItemsSource，我在发布的每一个元素观点得到5个值5对象的列表。

I want controls inside my PostView to be bound with properties of Current ItemsSource element. But whats happening is, say I have List of 5 objects set as ItemsSource, every element in my Post view gets 5 values.

所以我得到的，而不是1月25日PostViews初始化，5元的ItemsSource对象。

So I am getting 25 PostViews initialized, 5 per ItemsSource object, instead of 1.

下面是我的 PostView.xaml 是它可以帮助

Here is my PostView.xaml is it helps

PostView.xaml

<Grid x:Name="LayoutRoot" Background="{StaticResource PhoneBackgroundBrush}">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"></RowDefinition>
        <RowDefinition Height="Auto"></RowDefinition>
    </Grid.RowDefinitions>
    <ItemsControl
        ItemsSource="{Binding}">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <StackPanel>
                    <TextBlock Text="{Binding Path=User.Username, Mode=OneWay}" />
                </StackPanel>

用户在模型中，我绑定到一个对象的属性。
我怎样才能解决这个问题？

User is an Object property in the model I am binding to. How can I fix it?
