Binding custom dependency property in code behing

Question

Normal to do binding in code behind I do 

tb.SetBinding(TextBlock.FontSizeProperty, b);

I have a user control with DependencyProperty UserControlProperty

How do I replace the TextBlock.FontSizeProperty with my UserControlProperty?

Answer 1

Since a custom dependency property is a static property of the usercontrol class you can simply use <UserControlClassName>.<DependencyProperty>

Answer 2

do you mean something like myUserContro.MyDependencyProperty? I tried but MyDependencyProperty is not available for the control, it doesn't show up in my intelesence once I put "Static" in front of the dp
