WPF如何获得一个用户控件继承一个按钮？ [英] WPF How to get a UserControl to inherit a Button?

问题描述

我创建了由一对夫妇椭圆和标签的用户控件。我说这只是罚款，另一种形式的东西都找pretty时髦。

I created a UserControl which consists of a couple ellipses and labels. I added it just fine to another form and things were looking pretty snazzy.

然后我就开始添加一些事件处理程序，发现我做对照没有暴露一个Click事件。哎呀。很容易解决，对不对？刚回到code-背后我做的用户控件，并让它继承按钮。

Then I went to start adding some event handlers and discovered that the control I made did not expose a Click event. Oops. Easy to fix, right? Just go back to the code-behind on the UserControl I made and let it inherit Button.

不幸的是，这样做造成了显示myControl分部声明一定不能指定不同的基类的消息。这令人惊讶，因为我没有宣布任何其他基类。搜索有问题的部分返回任何结果无论是。

Unfortunately, doing this caused a "Partial declarations of MyControl must not specify different base classes" message. This came as a surprise since I haven't declared any other base classes. Searching for the Partial in question returned no results either.

有没有办法战胜这个问题？如果没有，你会在这里是最简单的解决方法吗？我的目标很简单，就是让在用户控件Click事件。

Is there a way to defeat this issue? If not, what would be the easiest workaround here? My goal is simply to get a Click event on the UserControl.

推荐答案

是的，你声明其他基类:)只要信任编译器：）

Yes, you've declared other base classes :) Just trust compiler :)

当你写＆LT;用户控件...＆GT;＆LT; /用户控件＆GT; 在XAML中，你继承用户控件。如果你想继承一个按钮，使用＆LT;按钮...＆GT;＆LT; /按钮＆GT; 而不是和：在code隐藏文件按钮。

When you writing <UserControl ...></UserControl> in XAML, you are subclassing UserControl. If you want to subclass a Button, use <Button ...></Button> instead and ": Button" in code-behind file.

但我强烈建议你不要继承按钮，它给你的任务矫枉过正。您可以使用的MouseLeftButtonUp事件而不是Click事件。

But I'm strongly encourage you to not subclass Button, its an overkill for you task. You can use MouseLeftButtonUp event instead of the Click event.
