DependencyProperty Binding to a programmatically created ListBox

Im new to WPF / Silverlight so its hard for me to describe what i try to do. Maybe that is the reason i could not find a answer on Stackoverflow and Google.

I try to bind to a DependyProperty programmatically.

public static DependencyProperty MyDependencyProperty
        = DependencyProperty.RegisterAttached(
                            "...", 
                            typeof(...),
                            typeof(...),
                            new PropertyMetadata(...)
                      );

xmlns:MyXMLNS="clr-namespace:...."

<ListBox MyXMLNS:MyClass.MyDependencyProperty="...">
    // ....
</ListBox>

This already works as expected.

How can i get this done programmatically?

The format in code is always the same and just a non-verbatim translation if you know how the XAML is handled.

<ListBox local:Attached.Test="{Binding PathToProperty)"/>

var binding = new Binding("PathToProperty");
listBox.SetBinding(Attached.TestProperty, binding);

If you set other properties on the binding like ElementName you should set those before SetBinding. (This SetBinding method is just for convenience (if you only set the Binding.Path there even is another one), for non-FrameworkElements you need BindingOperations.SetBinding)
