Windows Phone 7 listpicker itemsource模板问题

我试图让列表选择器显示 iList 中的属性。当我运行应用程序时，出现的是绑定信息..不是那个属性..

这是xaml

 <phone:PhoneApplicationPage.Resources>
    <DataTemplate x:Name="lpkItemTemplate">
        <TextBlock Text="{Binding Operation}" />
    </DataTemplate>
    <DataTemplate x:Name="lpkFullItemTemplate">
        <TextBlock Text="{Binding Operation}" />
    </DataTemplate>
</phone:PhoneApplicationPage.Resources>
 <toolkit:ListPicker x:Name="lbOperation" Header="Operations"  SelectedIndex="0" 
                        FullModeItemTemplate="{Binding lpkFullItemTemplate}"
             ItemTemplate="{Binding lpkItemTemplate}"
                        Grid.Row="5" 
                        >

和背后的代码，

        Dim Os As List(Of wsOperation.Operation) = e.Result
    Me.lbOperation.ItemsSource = Os

我认为这是一个模板错误，因为列表中的行数是当我单击列表选择器时出现。但我询问的属性（“操作”）不显示数据。相反，我显示了大约 10 行 wsOperation.Operation。

谢谢香农

~~~~~~~~~ 也许更多的信息将有助于找到可能的解决方案时列表选择器显示的内容..这就是列表选择器显示的内容

运行此页面ProcWP.wsOperation.Operation

这是当我单击上面的行时

ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation

I'm trying to get the listpicker to show a property that is in an iList. When i run the app, what comes up instead is the binding info.. not that property..

Here is the xaml

 <phone:PhoneApplicationPage.Resources>
    <DataTemplate x:Name="lpkItemTemplate">
        <TextBlock Text="{Binding Operation}" />
    </DataTemplate>
    <DataTemplate x:Name="lpkFullItemTemplate">
        <TextBlock Text="{Binding Operation}" />
    </DataTemplate>
</phone:PhoneApplicationPage.Resources>
 <toolkit:ListPicker x:Name="lbOperation" Header="Operations"  SelectedIndex="0" 
                        FullModeItemTemplate="{Binding lpkFullItemTemplate}"
             ItemTemplate="{Binding lpkItemTemplate}"
                        Grid.Row="5" 
                        >

and the code behind

        Dim Os As List(Of wsOperation.Operation) = e.Result
    Me.lbOperation.ItemsSource = Os

i'm thinking it is a template error because the number of rows in the list is the number that comes up when i click on the listpicker.. but the property i've asked ("Operation") is not displaying the data. Instead i get ~10 rows of wsOperation.Operation showing up.

thanks
shannon

这个问题的答案就在工具包里：ListPicker。我需要将 {Binding lpkFullItemTemplate} 更改为 {StaticResource lpkFullItemTemplate} 并与 itemTemplate 相同

，所以现在看起来像这样

<toolkit:ListPicker x:Name="lbOperation" Header="Operations"  SelectedIndex="1" 
                        FullModeItemTemplate="{StaticResource lpkFullItemTemplate}"
             ItemTemplate="{StaticResource lpkItemTemplate}"
                        Grid.Row="5" 
                        >

the answer to this problem was in the toolkit:ListPicker. I needed to change the {Binding lpkFullItemTemplate} to {StaticResource lpkFullItemTemplate} and same with itemTemplate

so it looks like this now

<toolkit:ListPicker x:Name="lbOperation" Header="Operations"  SelectedIndex="1" 
                        FullModeItemTemplate="{StaticResource lpkFullItemTemplate}"
             ItemTemplate="{StaticResource lpkItemTemplate}"
                        Grid.Row="5" 
                        >
