In my experience, using MVVM will slightly increase the amount of code, but in general it will reduce the complexity of the Code. This is a cost-effective transaction. Looking back at the MVVM illustration, you will notice that I have used fuzzy vertices "Y" and "update", without detailed instructions on how to do this. You can use KVO, just like MVC, but it will so

Windows presentation Foundation (WPF) and Silverlight provide a rich API for building modern applications, but it can be difficult to understand and consistently apply all the WPF features to build well-designed, maintainable applications. Where do I start? What kind of method is the correct application design method? The Model-view-viewmodel (MVVM) design pattern describes common methods for building WPF or Silverlight applications. It is also a pow

Some people asked me a few times ago, in mvvm mode, to nest the view in the view and switch the view. Write it down. Contentcontrol and datatemplate are mainly used. This is a viewmodel first idea. In fact, many mvvm frameworks also provide such functions. Bind viewmodel to contentcontrol to display the corresponding view. For example, Caliburn. Micro (CM framework ). Mvvmlight should have not been provided

Differences between Model-View-viewmodel and MVC and MVP design modes The Model-View-viewmodel design mode is the product of combining the MVP design mode with the WPF technology. It is common for Model-View-controller (MVC) design Patterns and Model-View-Presenter (MVP) design patterns have a major drawback when used in WPF: that is, they did not take into account the powerful data binding technology of
