2-Model ModelsIn this project there is only one data model, that is QQ account data. Then QQ account data has two attributes, one is the QQ number, one is the password.What we need to do in the MVVM architecture is "back and forth", so most of the data needs to be "data binding binding". After data binding we may need to modify, delete, add these dynamic operations, it is necessary to use the INotifyPropertyChanged interface (to notify the client, usu

capability than View.Or you can simply think that View is just a test method that is not very recommended.After this mode is applied, the unit test of ViewModel is required.Depends on any UI control. (if it does not correspond to ViewModel development, should it pass the test?To drive? TDD ?) 4, AttachBehavior Generally, using the WPF features such as Command, Binding, AttachProperty, View, andViewModel works well together. Suppose we have a Button,

In-depth introduction to WPF series of videos (special series)-introduction and improvement of mvvm (more than 300 difficulty) We haven't launched any new videos for more than a year, so it's a long time! This is a big contribution-up to 2 hours and 40 minutes. We will explain in detail the application of the Model-View-viewmodel in WPF development. This video i

the interface display. 6 Description Using MVVM in WPF can reduce the coupling between UI display and back-end logic code, which means that when you replace an interface, you only need to modify very little logic code to achieve it, even without modification. In WinForm development, we will generally directly manipulate the interface elements (such as: textbox1.text= "AAA"), so that after the interface c

To develop a WPF application, you have to mention MVVM. I'll show you a simple implementation of MVVM, mainly in the implementation of ICommand, but this implementation should not be used by many people in development, only for learning. Get ready: The interface is drawn in a simple box with a TextBox and button buttons. Start Next write ViewModel, note that Vie

When using WPF-MVVM development, the implementation of their own notification interface, Delegatecommand relatively less use, we are more use of the third-party MVVM framework, which Microsoft's own team provided by the PRISM framework, this framework is more functional, I now learn a limited, For the time being, let's introduce simple use.

Some UI elements of WPF can be directly bound with the command attribute, such as button But how to bind the trigger of many events to the command in viewmodel? The answer is to use eventtrigger. Continue the previous research on slider and modify interaction in view. If you change eventname to thumb. dragcompleted, the event is not triggered.The reason is: Because the command is hooked up to the slider, but the event is fired on the thum

PS: This article is from encyclopedia. The mvvm mode is mainly used to achieve the separation of views and logic. In the example of implementation, realcommand is used at the viewmodel layer.

The previous article briefly describes the use of Notificationobject in Prism, as well as Delegatecommand. This article is more simple, just describe how to use delegatecommand The ICommand interface is the first to provide a method with parameters, and we often encounter the use of that parameter is useless, Prism also helped us. Of course, Prism does not forget that we sometimes have to drop the parameters. In terms of definitions, we use ICommand definitions, like Delegatecommand and delegat
