Prism is a lightweight WPF framework used to build a composite WPF Application and try to separate the Ui and logic as much as possible. The process of understanding this framework is also a process of understanding the design model.

The "command" here is the "Command" in command mode. Almost every applicationProgramThis mode is used to copy, paste, undo, and other operations. We know that this mode isolates the operation requestor from the Operation execution logic, and it has good support for request queuing and repeated revocation operations, so it is widely used. While WPF further encapsulates and im

Recently I learned how to use the MVVM of WPF. In practice, I found that ComandParameter does not know how to pass it to ViewModel. I found some solutions on the Internet. Most of them use IComand to solve the problem as follows:
// The purpose is to pass in the selected row of the DataGrid to delete the public ICommand DelCmd {get {return new DelegateCommand
The above code can solve m
Xamarin. Forms + Prism (1) -- Development Preparation, xamarin. formsprism

Prism 5.0 source code for reading ModuleCatalog, graphpadprism5.0
Concept
ModuleCatalog is one of the main concepts in Prism. It is mainly used to save the available modules of an application. Every module is defined by ModuleInfo (including the module name, type, and location ).
Function implementation
ModuleCatalog inherits from IModuleCatalog. IModuleCatalog declares the following attributes and methods:
In the previous article, I wrote the model inotifypropertychanged interface implementation. In prism, A icationicationobject automatically implemented this interface, which is located in the Microsoft. Practices. Prism. viewmodel namespace. That is to say,Prism recommends that viewmodel inherit the icationicationobject class to automatically implement the inotify
Last week, the final version of prism 4.0, which supports Windows Phone 7, was released. Damian, Diego, Guido, And Ezequiel updated the prism training kit, this beta version of training kit includes five hands-on experiments covering the core concepts of Prism (modularity, bootstrapping, dependency injection, uicomposition and communication ):
Modularity lab:
The source code of this set of projects comes with the prism framework, covering the vast majority of practical problems we encounter during prism development. The following articles are my series of stocktrader RI (RI) studies in the last half month.ArticleCollection. A total of about 15 articles are expected to be attached to the topics of the prism Study Serie
Today, when I used Prism's ieventaggregator, I found that it was not working. The reason was analyzed later because the MEF dependency injection was not correctly set. Let's talk about the prism event mechanism first.
The observer mode is used to decouple the publishing and subscription of events. In prism, the two modules can communicate with each other and the basic classes of events can be placed in

Prism4, which has been used for a period of time, is not used to it at the beginning. Now I feel that this loose coupling mechanism has its own principle. Now I want to organize some things to facilitate my memory. When we implement the MVVM mode, the interaction between the foreground View and the background ViewModel is achieved through binding. The control trigger event binding involves several situations:
First, Control inherited fromButtonBase, MenuItemClass, such as: Button, RadioButton

The Prism framework needs to initialize the application when it starts. the Bootstrapper is used as the starting point.
Bootstrapper mainly involves creating and configuring module catalog, creating DI Container, configuring the default region adapter for UI, creating and initializing shell and initializing module.
