wpf contentcontrol

I think one of the core changes of WPF is that the control model has undergone an important change. In the big aspect, the controls (most of them) in the window do not have independent hwnd. In addition, the control can provide a variety of forms through the so-called template. In this article, let's talk about contentcontrol. The first part is to dynamically add controls and search controls. What is

not. The consideration for the content attribute may be due to the mandatory addition of the layout style of the Panel type. So if you put more than one control in the content attribute at the same time, the property 'content' is set more than once. error will occur, but you can do this. 3. Additional attributes This is an important assignment method. This allows you to define attributes for the parent node by attaching attributes. The most typical example is to define the elements in the

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

Introduction to WPF ControlsWith an introduction to the previous XAML language, we know that XAML is a tree structure, and that WPF controls, as part of the entire XAML tree, are also a tree-shaped structure. Let's look at a simple example."F:\01.Code\01.MyCode\WpfApplication1\WpfApplication1\Resources\. jpg"Width=" -"/> "Red"Foreground="Red"Verticalalignment="Center">"Green"Foreground="Green"Verticalalignm

Windows Presentation Foundation (WPF) Data Binding provides an easy and consistent way for applications to display and interact with data. Elements can be bound to data from various data sources in the form of Common Language Runtime Library (CLR) objects and XML. ContentControl (such as Button) and ItemsControl (such as ListBox and ListView) have built-in functions, so that a single data item or data item

The concept of "attribute elements" in this section can be described in a bizarre sense. 1. WPF implements object modeling with tag elements, two types: Control and container, which are used to load content and behavior, such as Button, the latter such as window. You can write this: 　 　　　 　 You can also do this: 　 　　　 　 That is, the image property of the original button and the TextBox property are extracted as objects. This is because

modify the Template attribute of the control. We define a new ControlTemplate to set the new value. Similarly, ControlTemplate also uses the TargetType attribute, which has the same meaning as the TargetType of the Style. The same is true for its x: Key attribute. Then, a Grid is used to represent the visual content of the control. The TemplateBinding is similar to Binding, indicating that the display color of the current Ellipse is synchronized with the Background attribute of the Button. Temp

dependency propertyThe various features provided by the WPF property system are primarily exposed through dependency properties. Therefore, the most important way to understand the property system is to understand exactly what functionality a dependency property provides. In this section, we'll make a brief introduction to the dependency property feature mentioned in this article.The first is the composition of the dependency property. If you need to
