NET 4.5 c＃用于我的购物门户网站。我正在使用Repeater来展示产品，我也使用标签来显示购物车产品数量。但我的问题是每次我将产品添加到购物车整页加载。我尝试过更新面板，但这也没有用。请建议我使用我的网站加载更快，并每次停止产品加载。
My master page where cart info is displayed is like this:

答案 0 :(得分：1)
这是因为您没有在分页查询中使用ajax。使用任何jQuery网格，并在数据库中编写分页查询以获取分页结果。永远不要使用Microsoft的Ajax Control Toolkit，即使Microsoft建议使用jQuery（http://www.jquery4u.com/plugins/10-jquery-grids/）
