Ajax UpdatePanel刷新的问题

scfobao 2008-12-17 08:36:05

在我的页面中有两个Panel
一个panel中放置了产品列表供给PopupControlExtender1弹出，选择的值返回给产品TextBox
另一个Panel中放置了一个Canlendar，由PopupControlExtender2弹出，选择的值返回给日期TextBox
两个Panel中都放置有UpdatePanel ，产品列表和Canlendar都放置在<contentTemplate></contentTemplate>中

在另一个UpdatePanel（UP3）中放置了一个Repeater，其DataSourceID指定为一个提供次品类型的SqlDataSource，
当页面第一次载入时，显示某某次品类型和一文本框等待输入次品数量；当产品和日期都选择了之后，希望能根据其将对应的
次品数量显示出来。

我用了两个方法均不行，
1、我用sm1.RegisterAsyncPostBackControl(Button1);注册了一个Button，
2、在PopupControlExtender.Commit()之后调用up3.update()

以下是源代码，请各位大佬帮忙
