我是asp.net网络应用程序，我想要包含ajax功能，我已经正确地添加了更新面板脚本管理器，但它仍然导致完整的回发， 我是否需要做任何额外的事情来在现有项目中包含ajax，以便它应该进行部分回发
可能导致完整回发的可能原因，
iam使用vissual studio 10，我的项目目标是.NET 4.0
我尝试过：
我试图包含异步回发触发器和定义的控件和事件触发器，使更新面板更新模式属性为conditional，子触发器属性为false，脚本管理器设置启用部分呈现为true 没什么用的

如果您没有绑定表单中的数据
<UpdatePanel>
<ContentTemplate>
your content
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="control_id" />
</Triggers>
</asp:UpdatePanel>
如果您要绑定数据，请使用
<UpdatePanel>
<ContentTemplate>
your content
</ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID="control_id" />
</Triggers>
</asp:UpdatePanel>
希望这会对你有所帮助。谢谢

您是否已尝试将更新面板的 ClientIDMode 设置为静态？我几天前就已经到了你的位置，这使得页面完全无法刷新。
