前提

入行已经7,8年了，一直想做一套漂亮点的自定义控件，于是就有了本系列文章。

官网：https://www.hzhcontrols.cn

GitHub：https://github.com/kwwwvagaa/NetWinformControl

码云：HZHControls控件库: HZHControls控件库，c#的winform自定义控件，对触屏具有更好的操作支持，项目是基于framework4.0，完全原生控件开发，没有使用任何第三方控件，你可以放心的用在你的项目中(winfromcontrol/winformcontrol/.net)。还有更丰富的工业控件持续增加中~~~

如果觉得写的还行，请点个 star 支持一下吧

欢迎前来交流探讨：企鹅群568015492

准备工作

日期控件将分为3部分进行处理，分别是，列表、日期面板、输入控件

将用到停靠窗体和基类控件，如你还没有了解，请移步查看

（十九）c#Winform自定义控件-停靠窗体

（一）c#Winform自定义控件-基类控件

开始

添加用户控件，命名UCTimePanel
