Common paging classes (without SQL, directly binding data)

Pagination | data | Performing data paging has always been a headache, and many paging controls have been created. But I used a few of the controls, itself to execute SQL, poor support for stored procedures, in order to facilitate, especially write a common page class, using PagedDataSource to achieve datagrid,datalist,repeater paging. Complete the previous page, the next page,
The last page, the first page, the total number of pages, the current number of pages, jump these basic features.
