asp.net中的更新面板导致完全回发

我有一个asp.net web应用程序，我想包括ajax功能，我添加了更新面板脚本管理器，但它仍然会导致完整的回帖， 我是否需要做一些额外的工作来将ajax包含在现有的项目中，以便它能够进行部分回发

有什么可能的原因导致邮件被退回

iam使用Visual studio 10和我的项目目标.NET 4.0

我所尝试的：

我尝试为控件和事件包含异步回发触发器和已定义的触发器，将“更新面板更新模式”属性设置为“条件”，将“子触发器”属性设置为“假”，并将“脚本管理器”设置为“启用部分渲染” 没用

您是否已尝试将更新面板的客户端模式设置为静态？几天前，我访问了您所在的位置，这使页面无法完全刷新。

您能分享源代码吗。如果你没有把你的问题说清楚，那就没用了。
