Data bindings can be implemented either in XAML or code, but they're much more common in XAML where they help to reduce the size of the code-behind file. However, when there are many views, there must also be many event handlers, which results in a lot of boilerplate code.ĭata binding automates this task and renders the event handlers unnecessary. It responds by transferring data from one object to another. An event handler can then be installed that is notified of these changes. The common solution is to define events that signal when a change occurs. To handle these changes successfully, the app must be notified of changes in these views or the underlying data. When the view changes, the underlying data must reflect that change, and similarly, when the underlying data changes, that change must be reflected in the view. Often the views represent values from an underlying data source, and users manipulate these views to change that data. One of the primary tasks of the app is to keep these views synchronized and to keep track of the various values or selections that they represent. NET Multi-platform App UI (.NET MAUI) app consists of one or more pages, each of which typically contains multiple user-interface objects called views.
