Paging is one of the most commonly used functions in Web applications. In ASP.NET, although it comes with a DataGrid (asp.net 1.1) and GridView (asp.net 2.0) controls that can be used for paging, its paging function does not Unsatisfactory, such as poor customizability, inability to implement paging function through Url, etc., and sometimes we need to paginate DataList, Repeater or even custom data binding controls. Manually writing paging code is not only technically difficult, the task is cumbersome, but also the code The reuse rate is extremely low, so paging has become one of the biggest headaches for many ASP.NET programmers.
In response to the shortcomings of ASP.NET paging controls, AspNetPager proposed a unique solution to the paging problem in ASP.NET, that is, the paging navigation function and the data display function are completely independent, and the user controls the acquisition and display of data. Therefore, it can be flexibly used wherever paging navigation functions need to be implemented, such as implementing paging for data-bound controls such as GridView, DataList, and Repeater, presenting custom paging data, and making image browsing programs, etc., because the AspNetPager control and data are Independent, so the data to be paged can come from any data source, such as SQL Server, Oracle, Access, mysql, DB2 and other databases as well as XML files, in-memory data or data in cache, file systems, etc.

The main functions of AspNetPager:
1. Support paging through Url:
In addition to providing the default PostBack paging method similar to DataGrid and GridView, AspNetPager also supports paging through Url. Like paging in most ASP programs, the Url paging method allows users to enter the corresponding address in the browser address bar. Directly entering the specified page also allows search engines to search the content of all paginated pages, so it has the advantages of being user-friendly and search engine-friendly. Regarding the differences between Url paging and PostBack paging methods, please refer to the comparison of Url and PostBack paging methods.
2. Support Url rewrite (UrlRewrite) function in Url paging mode
Url rewriting technology can make the Url displayed to the user different from the actual Url. Url rewriting technology is widely used in search engine optimization (SEO), redirecting page paths after website reorganization, and providing user-friendly Url. AspNetPager supports Url rewriting technology allows you to customize the Url format of paging navigation and implement Url rewriting;
