Separation of Concerns (decoupling) or So C is a principle that promotes best practices for software architecture.A ‘concern’ can be considered as an aspect of software functionality.
HTML defines the content structure, CSS defines content presentation and Java Script defines how the content interacts and behaves with the user.
To realize the So C principle, many Design Patterns have emerged over the years.
It leverages the rich data binding capabilities of the XAML platform to expose the view model to the UI through the view's Data Context property.
The business layer is also termed as Model whereas the View Model layer is responsible for exposing data objects from model to the UI using Data Binding.
My specific case was a bit more complex because I was binding to the page View Model (which I didn’t want to instantiate more than once as it made web service calls) to a Combo Box in a Data Template for a cell in a Grid View.
There wasn’t much documentation regarding that which I found that was helpful, so I’ll do another post about that later.Abstract: The MVVM Light toolkit provides a lot of boiler plate code to implement Model-View-View Model based applications quickly and gives the user the freedom to customize and design the application.This article shows how to get started with MVVM development for WPF applications.Currently the templates are only provided for Visual Studio 20 for the Pro, Premium and Ultimate editions. To do so, open an existing WPF project in Visual Studio In the following steps, we will make use of MVVM Light for implementing a WPF application that performs some basic database operations.In these steps, we will make use of the following features of MVVM Light: Step 1: Open Visual Studio and create a WPF Application and name it ‘WPF_MVVMLight_CRUD’.You can read more about the different binding modes here. Background in the payment industry, particularly in card switching and related system architecture.
