构建复合自定义控件WPF的最佳实践 [英] Best practices of building composite custom controls WPF

问题描述

您能告诉我有关主演的信息吗？
例如，我需要创建新的自定义控件，该控件必须从datagrid和工具栏派生。我希望该新控件公开/传播基本控件的属性，以便可以轻松访问它们。我知道的唯一方法是派生一堂课。然后，后代会自动获取祖先的所有属性。但是禁止在C＃中进行多次派生，因此我不知道如何公开第二个控件的属性和其他行为...还需要对此类自定义控件进行样式化和模板化。

Can You tell me about subj? For example I need to create new custom control that must be derived from datagrid and toolbar. And I want that new control to expose/propagate properties of base controls in order they to be accessed easily. The only way I know is deriving a class. Then descendant automatically gets all properties of ancestor. But multiple deriving in C# is prohibited, so I don't know how to expose properties and other behavior of second control... Styling and templating of such custom control is also needed.

谢谢！

推荐答案

在WPF中，继承是 out。 ; O）实际上，在WPF之前已经很复杂了，但是有了WPF，您可以获得各种非常强大的选择。

In WPF inheritance is "out". ;O) Actually, it was complicated before WPF already, but with WPF you get various really powerful alternatives.

对于基本控制，我最好还是使用组合，创建一些usercontrol并使其包含ToolBar和DataGrid。如果需要从外部操纵它们，则可以将它们公开为公共属性。

For the basic control I thing you'd better go with composition, create some usercontrol and make it contain a ToolBar and a DataGrid. You can then expose these as public properties, if you need to manipulate them from outside.

对于特殊功能的添加，附加属性是一种非常通用的机制。

For special feature additions, attached properties are a very versatile mechanism.
