C#winform自定义翻页控件详解-创新互联
C# winform中自定义的翻页控件，自己设计，供大家参考，具体内容如下
成都创新互联公司主营雨花台网站建设的网络公司,主营网站建设方案,app开发定制,雨花台h5重庆小程序开发搭建,雨花台网站营销推广欢迎雨花台等地区企业咨询1.主要是使用控件绑定点击事件
用到的控件分别为picturebox lable 上一页pbPage_Prev 下一页 pbPage_Next 首页 pbPage_Begin 尾页pbPage_End 是picturebox控件加背景图
“第 页/ 共 页” 是一个lable “labPageInfo” 在lable上面加了一个隐藏的textbox 控件 “txtPageInfo”
2.将这个翻页的功能单独写在用户控件 ucPageTurn 里面 然后在每个页面直接应用就可以了
下面只是把ucPageTurn写了出来
还需要在winform页面上应用上
