占位符不起作用 [英] Placeholder not working

问题描述

大家好，



我在.aspx页面写了以下代码



< asp：PlaceHolder ID =PlaceTestrunat =server>

< asp：Timer ID =TimerTestOnTick =TimerTest_Checkrunat =serverinterval =60000>



< asp：UpdatePanel ID =updTestUpdateMode =条件runat =server>

< triggers> < asp：AsyncPostBackTrigger ControlID =TimerTestEventName =Check/> < contenttemplate>

< uc1：ctrlTest ID =ctrlTest1runat =server/>









还有相关的计时器事件也写在下面。

protected void TimerTest_Check（object sender，EventArgs e）

{

ctrlTest ctrl =（ctrlTest）LoadControl（ctrlTest.ascx）;

PlaceTest.Controls.Add（ctrl）;

}



目的是在每个指定的时间间隔后刷新更新面板中的控件。但我没有得到任何输出。它显示空白页。



请帮助

我没有看到你的代码有任何错误，



你可以尝试这个 http://msdn.microsoft.com/en-us/library/system.web.ui.timer.interval.aspx [ ^ ]



可能是占位符名称与主页不匹配
