![]() ![]() Why such a difference? One reason is the matter of efficiency. NET are a language feature that combines a get/set pair of methods with some internally stored value (such as the text of a TextBox), Dependency Properties, while still being accessible through get/set, store their values in an external, highly optimized place. These XAML properties are implemented as “Dependency Properties.” The main difference is that while properties in. What may not be obvious to the casual observer is that in XAML, these properties are slightly different from “normal” properties. This includes elements with properties that can be used to change the appearance or behavior of said elements. In more sophisticated terms, Attached Properties are a feature that allows developers to extend UI objects with arbitrary features in very powerful ways.īut let's start at the beginning: In systems such as WPF (Windows Presentation Foundation) or WinRT (what the industry generally refers to as the “XAML Dialects”), UI elements and controls behave much like you would expect them to behave. In simple terms, these are properties that can be arbitrarily attached to just about any object in the UI hierarchy and allow attaching data that needs to be associated and stored with those objects. ![]() All XAML dialects support a feature that is used mostly by accident, yet goes overlooked for its vast potential: Attached Properties. ![]()
