C# winform自定义翻页控件详解

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

1.主要是使用控件绑定点击事件

C# winform自定义翻页控件详解

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

3. 你在资源管文件里面创建的control 文件夹里面，创建了一个用户控件ucpageturn ，那么在工具栏里面会自动显示你刚刚写的ucpageturn组件，把它拖到页面上，将这个组件的名字叫做ucpages，这样ucpageturn里面的控件就可以进行编辑
