前段时间项目需要WPF分页控件，百度了许久，也没有找到一个合适的开源控件，不是太丑，就是封装的控件无法使用，最后决定自己写一个。
写的时候，参照百度搜索分页对传统分页控件做了简化。细致地看了下百度搜索分页功能，百度分页控件默认是10页（如果结果列表小于10页，则显示实际页数），除了10个页面元素外，最左和最右两侧各有一个按纽，即前一页和后一页；

• 传统分页控件中有首页和末页功能，百度弃之；
• 传统分页控件中有分页容量设置功能，百度弃之；
• 传统分页控件中有输入页码跳转功能，百度亦弃之；

这么多功能都没有，这个分页能好用嘛，又仔细研究，于是发现一个小秘密，百度分页的10个小页面元素，以第6个为中心，当点击任一个页码，会将该页码从当前位置移动到第6个位置，从起始到结束位置的其他页码都顺延移动，这样一来，在分页导航的过程中，使用起来确实也很方便，最大程序减少了点击次数，也简化了操作，不需要忆和分别那么多功能，想分页，就click。这种简化的背后，其实暗含了细致的用户使用行为分析，即一个人在使用分页的过程中，因为通常不太会记得或者知道自己的想要的要素在哪一页，更倾向于按顺序查看各页，因此列出10个页加上click当然是最简单又能满足需求的方式，通过一个移动选中页到中心位置，实际上一次点击，加载多个可能想看的页面，使10个页面的范围尽量扩大，避免了频繁点击[前一页]、[后一页]的无聊操作，这样一来，即使功能大大简化，但使用起来似乎更方便了。一个小小的功能，都能看出用心可贵。

闲话不多说，看下控件真身：

再看下百度的：

是不是很像，哈哈，自己做的，美工还欠点；

上代码：

XAML就不上了，后面直接提供个下载的；
