XAML DataContext DesignInstance with nested types

问题

Is it possible to specify a nested type for d:DesignInstance in XAML? And if so, how?

If I have the following class structure:

namespace MyApp
{
    public class OuterClass
    {
        public class InnerClass
        {
             public string SomeData {get;set;}
        }
    }
}

How can I use the InnerClass type as a DesignInstance? The following doesn't work:

<phone:PhoneApplicationPage
    ...
    xmlns:local="clr-namespace:MyApp" 
    ...
    d:DataContext="{d:DesignInstance Type=local:OuterClass.InnerClass}"

回答1:

Try changing . to +. Something like:

<phone:PhoneApplicationPage
    ...
    xmlns:local="clr-namespace:MyApp" 
    ...
    d:DataContext="{d:DesignInstance Type=local:OuterClass+InnerClass}">
