C# 使用Ajax的Asp.Net页面每次都会重新加载整个页面，为什么？
以下是一个不起作用的片段：C# 使用Ajax的Asp.Net页面每次都会重新加载整个页面，为什么？,c#,asp.net,ajax,C#,Asp.net,Ajax,以下是一个不起作用的片段： <form id="form1" runat="server"> <div> This is the time : <br /> <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> <asp:UpdatePanel ID="Updat
<form id="form1" runat="server">
<div>
This is the time :
<br />
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="conditional" ChildrenAsTriggers="false">
<ContentTemplate>
<asp:TextBox ID="txtDate" runat="server"></asp:TextBox>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnRefresh"/>
</Triggers>
</asp:UpdatePanel>
<br />
<asp:Button ID="btnRefresh" runat="server" text="Refresh" OnClick="btnRefresh_Click"/>
</div>
</form>
为什么要重新加载页面而不仅仅是UpdatePanel？尝试将ChildrenAsTriggers设置为True。我删除了“ChildrenAsTriggers”，并为触发器设置了“EventName” 您可能还需要致电： UpdatePanel1.Update（）位于click函数中，因为UpdatePanel设置为“条件”
<form id="form1" runat="server">
<div>
This is the time :
<br />
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="conditional">
<ContentTemplate>
<asp:TextBox ID="txtDate" runat="server"></asp:TextBox>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnRefresh" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
<br />
<asp:Button ID="btnRefresh" runat="server" text="Refresh" OnClick="btnRefresh_Click"/>
</div>
</form>
我重新测试了你的代码，一切正常 当您点击刷新按钮时，它会更新更新面板中文本框中的时间，同时也会更新Windows标题栏中的时间 刷新按钮不会更新更新面板外部的任何控件
<form id="form1" runat="server">
<div>
This is the time :
<asp:Label runat="server" id="lbltemp"></asp:Label>
<br />
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="conditional" ChildrenAsTriggers="false">
<ContentTemplate>
<asp:TextBox ID="txtDate" runat="server"></asp:TextBox>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnRefresh"/>
</Triggers>
</asp:UpdatePanel>
<br />
<asp:Button ID="btnRefresh" runat="server" text="Refresh" OnClick="btnRefresh_Click"/>
</div>
好吧，我明白了，因为每个人都成功了，但不是我，所以我想这是一个配置 事实上，您需要在web.config中有一些标记才能使用Ajax框架，我缺少一些标记，现在是我的web.config：

我会给每个给我足够提示的人+1。谢谢大家我复制了DefaultPage中的代码，并在单击中添加了更新方法，整个页面仍在刷新。。。我需要在配置文件中设置一些东西吗？这不重要，因为按钮不是updatepanel的子项，它不在updatepanel中。我一定是出了什么问题，因为它不工作。每次我按下按钮时，标题和标签、文本框都会更新。我在IE8状态栏中没有遇到一个javascript错误，上面写着：网页错误详细信息：消息：“Sys”未定义…Daok，Sys未定义表示您没有在浏览器上加载客户端文件。尝试检查web.config设置，可能是它缺少一些处理程序设置。另外，您运行的是http还是https？
