Silverlight Custom Property Inheritance

I have a class inheriting from UserControl, with a custom DependencyProperty. I put a standard button inside (not necessarily it's immediate child) and I want to get the value of my custom DP on the button, like this:

usercontrol.MyDependency = "hello";
var x = button.GetValue(MyUserControl.MyDependencyProperty);

It's pretty much property inheritance inside the visual tree, but x is null, instead of "hello".

Is property inheritance like this possible in silverlight?
(And no, I do not want to put userControl into its own DataContext, I need the DC for my ViewModel, MyDependency is a property of the view, not the viewmodel)

Solution

  • It is available to a few native properties only. And you cannot enable it for custom properties.
