（三十一）c#Winform自定义控件-文本框（四）
官网
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。

准备工作
终于到文本框了，文本框将包含原文本框扩展，透明文本框，数字输入文本框，带边框文本框
本文将讲解带边框文本框，可选弹出键盘样式，继承自控件基类UCControlBase
同时用到了无焦点窗体和键盘，如果你还没有了解，请前往查看
开始
添加用户控件，命名UCTextBoxEx，继承自UCControlBase

你也许注意到了m_frmAnchor_VisibleChanged事件，当键盘窗体显示的时候，启动手写输入软件（这里用了搜狗的手写），将手写软件窗体包含进键盘窗体中来实现手写功能
