无法绑定到属性

Question

I've got the following markup.

<TextBox x:Name="Address" 
         Text="{x:Static local:MainWindow.Boundie.SomeProp}" 
</TextBox>

In the code behind I have a static property like so.

static Something Boundie { get; set; }

public class Something { public String SomeProp { get; set; } }

The problem is that it nags that "type expected" when I hover over Boundie and "static member expected" when I hover over SomeProp . When I leave out the latter, it only complains that the expected type is String but it only sees Something .

How do I bind to a static member's non-static field?

Why I want to do that? Because I want to reuse the domain object model and those classes are not equipped with static members.

Answer 1

SomeProp is instance property so you cannot use x:Static to access that. You can bind to it using combination of static Source and Path

<TextBox ...
         Text="{Binding 
           Source={x:Static local:MainWindow.Boundie}, 
           Path=SomeProp}"/> 

Answer 2

<object property="{x:Static prefix:typeName.staticMemberName}" .../>
