The identifier of the dependency property to set.
The new local value.

Not all Windows Runtime properties as used by XAML are dependency properties. A DependencyProperty identifier needs to exist and it must be available as a public property of an owning object, typically the object that registered the property.
For app user-code, calling
SetValue is not typically necessary. Usually, a Windows Runtime dependency property or a custom dependency property has a conventional property that wraps it, and you can just set the property value through a conventional dotted usage. Cases where you might still use
- You are defining a custom dependency property. You will call
SetValueas part of defining your own property set accessor for a conventional property usage. For more info, see Custom dependency properties.
- You are defining a callback or are in some other scope where you are already being passed a DependencyProperty identifier, and it is possible that more than one dependency property exists that you might want to interact with in that scope. In these cases it is probably simpler to call
SetValue, passing the identifier.
