This may be customer records in a database, or product information on a website, or anything else.
They allow you to attach a value to an object that does not know anything about this value. Each layout panel needs different data to align its child elements. Since you can write your own layout panel, the list is infinite.As I mentioned, MVVM can make developing applications in WPF efficient, quick, and highly maintainable.Now that I’ve covered some of the basic technological advances in WPF, mainly Data Binding, Commands, and Templating, it’s time to bring everything together, and demonstrate how this improves our jobs as developers.So you see, it's not possible to have all those properties on all WPF controls. They are defined by the control that needs the data from another control in a specific context.
For example an element that is aligned by a parent layout panel. Left property of a button aligned within a Canvas panel, you write it like this: If you want to listen to changes of a dependency property, you can subclass the type that defines the property and override the property metadata and pass an Property Changed Callback.In this case we can coerce the value within the allowed boundaries.
