What's the code-behind equivalent of {Binding}?

Question

What's the code-behind equivalent of this code?

<SomeControl SomeProperty="{Binding}"/>

(If I wanted to do that in the code-behind of SomeControl instead of in the consumer's XAML.)

That is, how do I construct a Binding object such that I bind directly to the DataContext of my current object, instead of to some property?

Answer 1

Since {Binding} is just a shortcut for {Binding Path=.}, it should be just as simple as

SomeControl.SetBinding(SomeControl.SomeProperty, new Binding("."));

Answer 2

Take a look at BindingOperations.SetBinding:

BindingOperations.SetBinding(myControl, MyControlClass.Property, new Binding(...));
