使用部分代码：
<c:NumericBox VerticalAlignment="Bottom" Width="200" BorderBrush="#ddd"
BorderThickness="1" Margin="20"/>UserControl与CustomControl区别
- 自定义控件：注重控件对象的功能，必须遵守WPF的控件规则
-
- 完全自己实现一个控件 继承现有控件进行功能扩展，并且添加新功能 WPF的控件要求
- 后台代码（控制逻辑）和Generic.Xaml（样式 模板）进行组合
- 支持模板重写
- 继承Control
- 用户控件：注重复合控件组合使用，非常灵活，可以根据控件开发人员自己的意愿进行功能处理
-
- 多个现有控件的集合，组成一个可复用的控件组
- XAML和后台代码组成 绑定非常紧密
- 不支持模板重写、样式
- 继承UserControl
