基于Ajax技术的ASP.NET数据分页

Data Paging Based on the Ajax Technology in ASP.NET

在Web应用系统中经常在页面中浏览大量的数据,在系统的开发过程中必然要遇到数据分页的问题,ASP.NET提供了多种数据分页处理方式,但在技术上都是采用同步传输方式,这种方式在提取数据时用户等待的时间较长,服务器负担较重.本文在分析传统数据分页解决方案的基础上,以学生信息浏览查询为实例,详细介绍了在ASP.NET中基于Ajax技术实现数据分页的方式.结论是基于Ajax技术的数据分页采用异步数据传输,分页时通过局部更新数据,无需重新加载整个页面,大大减少了用户等待的时间,减轻了服务器的压力负担,提高了数据查询效率.

A large amount of data is often browsed in the Web application system, so the problem of data paging is bound to occur in the process of system development. ASP.NET offers many data paging approaches, but technically all using the synchronous transmission mode. Using this way to extract data causes the user waiting longer and heavier burden on the server. Based on the analysis of traditional data paging solution, through an example of browsing and querying student information, this paper introduces in detail implementation of data paging based on the Ajax technology in ASP.NET. The conclusion is that data paging based on the Ajax technology using asynchronous data transmission, when paging through updating local data, without reloading the whole page, greatly reduces the users＇ waiting time, lightens the burden of the server, and improves data query efficiency.
