为什么要自己写控件页不用网上成熟的控件呢？
理由：
1：网上成熟的控件封装性太强
2:功能太多，有些用不着
3:不太适用自己实际应用
在前两篇文章中,本人试着探索自定义控件的写法,当时写的不太好,功能也少,现在在两篇文章的基础上加以整理和改造,完成了下面的控件.
功能:
1:支持url参数分页
2:运行回发事件分页
3:可以自定义样式( 样式的名称是写死的,用户只能更改样式内容)
4:本控件图例
在页数多的时候,用户可以设置省略号前面和后面显示的数量,上图设置都是5
5:可以设置跳转到文本框的显示与否
说明:本人参考了
AspNetPager控制的源代码
主要目的是:学习自定义控件的用法,可能结合自己的实际应用来写出适合自己的控件
代码有点长,本人都写在一个文件中了,希望各位指点:
代码如下:
