How to Set TargetNullValue to Visibility.Collapsed in Binding

Question

I'm binding TextBlock.Visiblitiy to something, and I want to set the Binding.TargetNullValue to Collapsed, how can I do it in XAML?

This one How do I set TargetNullValue to a date? does not work in Silverlight. (No x:Static).

This is working for me in SL4:

<TextBlock Text="Text" Visibility="{Binding Foo, TargetNullValue=Collapsed}"/>

Where Foo:

public Visibility? Foo { get; set; }

Hmmm, this is a workaround though it works. As you know, Visibility.Collapsed is a constant, so there should be no instance to refer to it. – Dishonest

@PeterLee Well... ok. But maybe I don't fully understand your problem. Why is it just a workaround for you? Could you please update your question with some sample code, XAML to be clear what you are trying to achieve? – Falstaffian

I tried your method before, but I misspelled the Collapsed . What a mistake! It's working. Forget my previous comment. – Dishonest
