我想知道如何使用CollectionViewSource在Expression Blend中显示设计时间数据,该数据位于SampleData.xaml中？在更改我的代码以使用CVS之前,我使用了一个ObservableCollection.我需要对其中的项进行过滤和排序,因此我更改了代码以使用CVS.现在,我的设计师抱怨无法使用适当的结构填充SampleData的NextItems以显示在Expression Blend中.这是我在app中使用的一些代码：

Mainviewmodel.cs

class Mainviewmodel
{
    public Mainviewmodel()
    {
        AllItems = new ObservableCollection<Itemviewmodel>();
        NextItems = new CollectionViewSource();
        NextItems.Source = AllItems;
    }

    public CollectionViewSource NextItems
    {
        get;
        private set;
    }

    public ObservableCollection<Itemviewmodel> AllItems
    {
        get;
        private set;
    }

    some functions to fill,filter,sort etc...
}

MainView.xaml：

<phone:PhoneApplicationPage
    ... some other stuff ...
    d:DesignWidth="480"
    d:DesignHeight="728"
    d:DataContext="{d:DesignData SampleData/SampleData.xaml}">

    <Grid
        x:Name="LayoutRoot"
        Background="Transparent">
        <controls:Panorama>
            <controls:PanoramaItem>
                <ListBox ItemsSource="{Binding NextItems.View}">
                    <ListBox.ItemTemplate>
                        <DataTemplate>
                            <StackPanel>
                                <Image Source="{Binding Image}" />
                                <StackPanel>
                                    <TextBlock Text="{Binding FullName}" />
                                </StackPanel>
                            </StackPanel>
                        </DataTemplate>
                    </ListBox.ItemTemplate>
                </ListBox>
            </controls:PanoramaItem>
        </controls:Panorama>
    </Grid>
</phone:PhoneApplicationPage>

SampleData.xaml

<local:Mainviewmodel
    xmlns:local="clr-namespace:MyAppNamespace"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:swd="clr-namespace:System.Windows.Data;assembly=System.Windows" >
    <local:Mainviewmodel.AllItems>
        <local:ItemModel
            FullName="Dummy"
            Image="/Images/dummy.png" />
    </local:Mainviewmodel.AllItems>

    <local:Mainviewmodel.NextItems>

        How to fill the CollectionViewSource's Source?

    </local:Mainviewmodel.NextItems>
</local:Mainviewmodel>

所以我找不到答案的问题是如何在SampleDate.xaml中填充NextItems的Source？任何帮助将非常感激.

public class Mainviewmodel
{
    public Mainviewmodel()
    {
        AllItems = new ObservableCollection<Itemviewmodel>();

        if (DesignMode.DesignModeEnabled)
        {
            AllItems = FakeDataProvider.FakeDataItems;
        }
        NextItems.Source = AllItems;
    }

    public CollectionViewSource NextItems
    {
        get;
        private set;
    }

    public ObservableCollection<Itemviewmodel> AllItems
    {
        get;
        private set;
    }
}
