Get and set WPF custom attached property from code behind

问题

I generate objects of framework Rectangle class (which is sealed) and programmatically add them to Canvas. I want to add some information to that objects. Is there such a possibility? I can get and set attached properties in XAML but these is not useful for me.

回答1:

You can set attached properties in code, something like this:

OwningClass.SetMyAttachedProperty(textBox, true);
