The source is unknown. 1. PrerequisitesIt 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. BirthTo solve problems in the real world, we need to abstract things in

WPF Learning (III)-dependency attributes and wpf learning dependency attributes When I was learning about WPF, I was reading a book called "go deep into WPF. The dependency and additional attributes are being discussed on the entire 20 pages. I still don't understand them after reading them several times. It's really d

The examples in the WPF self-Learning Primer (10) WPF MVVM Simple introduction seem to run without problems or can be updated. But that's not the right way to use MVVM. 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

Through the previous introduction, we know that WPF supports using Style Setters to modify the property value of a control to change its appearance. We know that any control of WPF has a visual tree and a logic tree. However, Style has its own limitations: it can only modify the attributes of the existing tree structure of the control, but cannot modify the tree hierarchy of the control. In practice, we oft

in the. NET Framework DLL name, The dll version number, internal implementation, and size are different. Why? As we all know, the Silverlight installation package needs to be downloaded and installed. If the package is too large, it is definitely not suitable. So in order to compress. net framewrok core DLL, such as system. core. DLL, system. some classes that cannot be used by Silverlight, such as DLL, are removed (I guess O (pipeline _ runtime) O ). Therefore, Silverlight has fewer class impl

Implement custom virtual containers (implement VirtualizingPanel) and WPF custom controls in wpf Implement custom virtual containers in WPF (implement VirtualizingPanel) During the development of WPF applications, performance issues are usually taken into account for the presentation of large data volumes.

: this is a notification event when the new value of the property value is bound. Here, the obtained value is used to assign a value to the control. By now, the Time dependency attribute is half done.The TimePicker attribute depends on the binding of the Time attribute. The binding method is simple, for example. If Time is a common. net attribute rather than a dependency attribute, the binding method cannot be used in this way. If you add a common at

Introduction to three WPF templates and three wpf templates WPF supports the following types of templates: (1) control template. A control template can apply a custom template to all controls of a specific type or an instance of a control. The ControlTemplate determines the control's appearance. It determines what the control looks like. Therefore, the control te

application classIn the application class, we can write about the processing method (handler) of startup, Exit, sessionending and other source events.There is also a way to add a logic-override onxxx method when these events are triggered (OnXxx refers to the handling of the corresponding event). These methods are the source methods that the application class executes when an event is triggered. This way you can just rewrite the method in App.xaml.cs.The following
