Asp.net MVC 2 simple and simple development custom controller base class

Source: Internet
Author: User

In the past, when I used Asp.net, I always customized a base class to inherit the page class to implement some common operations on the page to reduceCode. Asp.net MVC 2 does not have the paging function. Implement the paging function in the base class. define common paging variables, such as recordcount, pagesize, and curpage, on the page. The pagination string is assigned to viewdata ["page"] Through getpager (), and viewdata ["page"] is directly output to the view page.
