将数据绑定到WebBrowser

Question

我将数据绑定到列表视图，需要在Web浏览器中显示HTML字符串。我该怎么做？这是清单：

<ListBox Margin="0,0,-12,0" ItemsSource="{Binding}" Name="postsList">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <StackPanel Margin="0,0,0,17" Width="432">
                <TextBlock Text="{Binding Path=name}" TextWrapping="NoWrap" Style="{StaticResource PhoneTextSubtleStyle}"/>
                <TextBlock Text="{Binding Path=content}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextNormalStyle}"/>
                <phone:WebBrowser Source="{Binding Path=webContent}" Margin="12,-6,12,0" />
            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

TIA， ng93
