ASP.NET UpdatePanel执行完全回发而不是部分回发
[英]ASP.NET UpdatePanel doing full postback instead of partial postback
问题描述
我正在尝试做一个简单的页面，该页面会进行一些计算并将其很好地显示在页面上。 我希望隐藏计算，因此我决定在服务器上的代码背后进行所有数学运算。 但是，当我单击“计算”按钮时，不需要刷新整个页面。 因此，我试图使用UpdatePanel来更改表内容（页眉和页脚应保持不变）。
但是，每当我单击“计算” /“重置”按钮时，整个页面就会闪烁起来，就好像它在进行完整的回发一样。
我首先尝试在2个表周围有2个UpdatePanels，这些表实际上具有要更新的值（每个表都带有其AsyncPostBackTriggers）和任何UpdatePanel外部的Buttons，但是结果与发布整个页面的结果相同。 因此，我想将其简化为当前的页面，因为它位于单个UpdatePanel中。
我还尝试将microsoft示例中的代码复制到我的页面中（下面的代码仍在页面上，并且仅包含我的页眉和页脚），并且它们的UpdatePanel也会导致整个页面进行回发（ https：// msdn.microsoft.com/zh-CN/library/bb399001.aspx ）。 我已经检查了web.config，它已设置为使用AJAX。

UpdateValues（）仅计算要在网页上显示的______Value变量。
这是我将页面简化为Microsoft示例的尝试（它仍然像显示完整的回发一样闪烁整个页面）：

用这个
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="resetButton" />
<asp:AsyncPostBackTrigger ControlID="calculateButton" />
</Triggers>
代替
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="resetButton" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="calculateButton" EventName="Click" />
</Triggers>
