Observer mode-New Mode

The customer requested that all the queries be paged. every page is annoying. just want to make the DataGrid a separate control. after the query is completed on each page, use the displayed control. the idea is very clear, the speed is complete, debugging, error, the original damn paging control has to execute a query again! This public control cannot always perform queries on the query page one by one. Do you think you can make a notification? So you can add the event and debug it successfully.

 Code:

Private void page_load (Object sender, system. eventargs E)
{
// Place user code here to initialize the page
Dgpagingcontrol1.equery + = new queryhandle (dgctrol1_q );
}

Protected ztemas. mastat. Web. mastatapp. usercontrol. dgpagingcontrol dgpagingcontrol1;
