Universal paging class (not executing SQL, direct binding data)

Data page has always been a problem with a more headache, and a lot of paging controls are also generated. But I have used several controls, it is necessary to perform SQL, support the storage process, for convenience, especially writing a general paging class, using PagedDataSource to implement the paging of DataGrid, DataList, Repeater. Complete the previous page, the next page, the last page, the top page, the total number of pages, the number of current pages, and the basic features are jumped.
