Silverlight 4: image in datatemplate not appearing on design surface

I'm trying to bind an image's source to a string in a listbox with a data template.

When I run the application, I see the image in the browser, but I cannot see it on the design surface.

Any ideas?

I have created a sample user control with a 3-row grid. In row 0 i just put the image In row 1 i put the image into a listbox item In row 2 I put the image into a datatemplate in a listbox bound to a resource

On the design surface, I can see the image in rows 0 and 1, but not in row 2.

public class PersonCollection : List<Person>
{
}

public class Person
{
    public string Name { get; set; }
    public string PictureURL { get; set; }
}

<Grid x:Name="LayoutRoot" Background="White">
    <Grid.Resources>
        <mystuff:PersonCollection x:Key="PersonList">
            <mystuff:Person Name="Rick" PictureURL="abc.jpg"/>
            <mystuff:Person Name="Bob" PictureURL="abc.jpg"/>
        </mystuff:PersonCollection>
    </Grid.Resources>
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition/>
        <RowDefinition/>
    </Grid.RowDefinitions>
    <Image Source="abc.jpg"/>
    <ListBox Grid.Row="1">
        <ListBoxItem>
            <StackPanel Orientation="Horizontal">
            <Image Source="abc.jpg"/>                    
            </StackPanel>
        </ListBoxItem>
    </ListBo开发者_如何学Gox>
    <ListBox Grid.Row="2" ItemsSource="{StaticResource PersonList}">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <Image Source="{Binding PictureURL}"/>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>
</Grid>

Just change the Person.Name Property to something else

Once I defined the PictureUrl property as an ImageSource in the Person class, the designer in the VS IDE showed the image.

public class Person {
public string Name { get; set; }
public ImageSource PictureURL { get; set; } }

Here's where I got the information from:
