C＃中的动态分页 [英] Dynamic Pagination in C#
问题描述
我是新来的
我和Marcus在 我正在尝试做的分页应该是这样的： 1 2 3 4 5 6 ... 101 当我点击数字5时，喜欢它显示这样的数字： 当我在最后几页我想看起来类似于第一个： 1 ... 96 97 $ 99 $ 100 $ 粗体数字是您当前正在查看的页面。 我希望只在有多于7个页面的情况下出现点，否则它应该看起来像一个正常的分页看起来像： 1 2 3 4 5 6 7 而不是粗体，我已经添加了一些CSS .. 我的原始代码是这样的... 这段代码显示所有的页面，而不是分组.. 任何帮助将不胜感激。 > 解决算法 只需要计算for循环使用大于或小于 确定逻辑 ' ' 希望我的逻辑能够帮助其他需要使用for循环分页的用户。 Johan 试试这样的事情。您需要根据您的需要定制它。 I'm new here I have the same problem as Marcus in here the paging I'm trying to do should look something like this: 1 2 3 4 5 6 ... 101 When i click on number 5 i would like it to display the numbers like this: 1 ... 3 4 5 6 7 ... 101 when I'm at the last couple of pages i want it to look similar to the first one: 1 ... 96 97 98 99 100 101 The bold number is the page that you're currently viewing. I want the dots to appear only when there is more than 7 pages available, if not it should look like a normal paging would look like: 1 2 3 4 5 6 7 instead of making it bold, i have added added a few CSS in it.. my original code is something like this... this code display all the pages, not grouping it..
I have modified the code above, but it only displays the first and last Pages,
Like if I have 10 Pages it only displays page 1 and 10 and not 1 2 3 ... 10 Any Help Would be appreciated.. Thanks Johan Solved the Algorithm } Just Needed to calculate the for loop using the greater or less than Ok the Logic ' ' Hope My Logic Helps For Other Users Who Needs Pagination using for loops. Johan Try something like this. You need to customize it as per your need.

我已经修改了上面的代码，但它只显示第一个和最后一个页面，
就像我有10个页面，它只显示页面1和10，而不是1 2 3 ... 10
