Navigation shortcuts to switch among the core components of the MVVM pattern
The Model-View-ViewModel (MVVM) is a modern architectural pattern for building applications based on XAML views. It allows us separate Model and View logic from View declaration while keeping the code clean and testable. This pattern is widely used in Xamarin.Forms applications and by convention each View is composed of 3 files:
- The XAML View (
.xaml) file where we describe our UI declaratively
- The View's code-behind (
- The View Model, a C# class that provide View logic through properties and commands that are bound to the view using the data-binding engine
Please read the Binding Context Resolution documentation to understand how MFractor associates view models with XAML views.
When working on a View you frequently switch back and forth this 3 files. Manually switching from the Solution Explorer or the open tabs is tedious and time-consuming. MFractor adds several shortcuts for navigating among those files.
Using the Navigation Shortcuts
The shortcuts becames available contextually when one of the 3 files that compose a group is open and active on the code editor. Shortcuts are available on the context menu of editor:
There are also very convenient and easy to remember keyboard shortcuts available:
|Go-To View Model||⌥ + ⇧ + 1||Alt + 1|
|Go-To Code-Behind||⌥ + ⇧ + 2||Alt + 2|
|Go-To View||⌥ + ⇧ + 3||Alt + 3|
Use the MVVM Wizard to create a XAML View with its corresponding code-behind and View Model files all at once, and using standards and conventions that you can set on project basis.
