Implement pagination without refreshing Ajax

Source: Internet
Author: User
Today I have nothing to worry about. in C #2.0, I used ajax to write an example of refreshing and fast paging. The time is too short. For the shortcomings, please point out that we should first put ajaxpro. DLL file to reference, you can go to http://www.schwarz-interactive.de/download according to your.. Net to select different DLL files. default. aspx. CS: public partial class _ default: system. web. UI. page
{
String connectstring = ""; // define your own connection string
Protected void page_load (Object sender, eventargs E)
{
Ajaxpro. Utility. registertypeforajax (typeof (_ default ));
} [Ajaxpro. ajaxmethod]
Public datatable getdatatable ()
{
Sqldataadapter ad = new sqldataadapter ("select * From tablename", connectstring );
Dataset DS = new dataset ();
Ad. Fill (DS );
Int num = Ds. Tables [0]. Rows. count;
Return Ds. Tables [0];
}}
