问题更新面板事件触发两次 [英] problem update panel event fires twice

问题描述

这里更新面板事件发生两次点击按钮

和记录插入两次为什么发生这种情况donno



请帮助< br $>

 <   asp：UpdatePanel     ID   =  upanelfolder    runat   =  server    UpdateMode   = 条件 >  
 <  < span class =code-leadattribute> ContentTemplate  >  

< asp：Label ID =Label1runat =serverText =<％= prod_name％>

 <   / ContentTemplate  >  
 <  触发器 >  
 <   asp：AsyncPostBackTrigger     ControlID   =  btn    EventName   = 点击    /  >  
 <   / Triggers  >  
 <   / asp：UpdatePanel  >  

< asp：Button ID =btnrunat =serverOnClick = btn_ClickText =添加/>



代码落后

 受保护的  Sub  btn_Click（ ByVal  sender 作为 对象， ByVal  e 正如 System.EventArgs）句柄 btn.Click 
 //插入查询
 结束  Sub  

解决方案

我面临同样的问题。请帮我。你怎么回事这个。



谢谢
