This blog will cover virtualization technologies in WPF.1. Data virtualization Typically, we say that virtualization means that the data source is not fully loaded, loading only the data that is currently needed for display to the user.

But if WPF is to inherit forms, I personally feel that I do not understand before: it is difficult, do not know how to deal with or can not inherit, but after understanding is ve

1. Prerequisites It can be said that mvvm is a model designed for WPF, or mvvm is just a variant of MVC. However, in practice, if you or your team are not used to binding, it makes little sense to study mvvm. In addition, I personally think that using command and creating a reasonable and simplified way to use command is equally important as using binding. 2.

As I said in the previous article, the goal of MVVM is to minimize the coupling of XAML files and CS files, separating the interface and business logic, so we do not write code in the view background as much as possible. But in this example,

Today to record the basis of the binding and the specific use of the binding, in WPF, binding is a very important feature, in the traditional Windows software, most are the UI driver mode, can also say that the event driver, This program pattern is deeply rooted in programmers who have worked for a few years, and as a WinForm upgrade, WPF changes the UI driver completely, and the core goes back to the data-
