按钮位于更新面板内。但每个按钮点击整页回发

-2

在我的代码为每个droup下来更新panel.it不回发。对于每个按钮单击完整回发是发生。但我的按钮在更新panel.i尝试触发asynpostback，在这种情况下，服务器端消息不显示。我也想要那个味精。按钮位于更新面板内。但每个按钮点击整页回发

我的代码是：

    <form id="form1" runat="server">

您忘记指定你所点击按钮，它在哪里。你有太多的UpdatePanel。每个人都单独行动。以太网只使用一个UpdatePanel来控制你想要使用它更新的所有控件。 – Aristos 2013-03-19 12:53:14

btnreset和btnInsertTime按钮的点击总是回传。 – user2181075 2013-03-19 12:58:09

如果我使用一个更新面板“btnSchedule”这个按钮点击执行服务器端代码没有验证 – user2181075 2013-03-19 12:59:30

你可以尝试像注册与脚本管理器控制：

protected void Page_Load(object sender, EventArgs e) 
{ 
    ScriptManager1.RegisterAsyncPostBackControl(ddlTechnology); 
    ScriptManager1.RegisterAsyncPostBackControl(ddlCourse); 
}

对于一个更新面板 – user2181075 2013-03-19 13:07:32

在这种情况下，服务器端代码无需验证即可执行 – user2181075 2013-03-19 13:12:10

按钮位于更新面板内。但每个按钮点击整页回发
