处理客户回发事件 [英] Handling client post back event

问题描述

你好！

我有一个问题，我需要处理一些元素的点击事件，如td我的表格获得回发购买我在服务器上注册的事件未被解雇的事件。



i实现了IPostBackEventHandler接口并实现了RaisePostBackEvent打击：



客户代码：

hello!
i have a question i need to handle the click event of some element like a "td" my form get postbacked buy the event i registered for that event on server isnt fired.

i implemented the IPostBackEventHandler interface and implemented the RaisePostBackEvent as blow:

client code :

window.onload = function ()
{
    document.getElementById("TestTd").onclick = function (e)
    {
        __doPostBack("First args", "Second args");
    }
}

和服务器上的代码

and code at server

public void RaisePostBackEvent (string eventArgument)
    {
        this.InfoLabel.Text = "Handled";   
    }

因为我说提交表单getts但是执行了RaisePostBack方法dos

非常感谢！

as i said the form getts submitted but RaisePostBack method dosnt get executed.
thanks alot!

推荐答案

__ doPostBack（''btnClick''，''Second args''）;

使用下面的代码代码

__doPostBack(''btnClick'',''Second args'');
use below code at code behind

if (Request["__EVENTTARGET"] == "btnClick")
{
   string secandArg = Request["__EVENTARGUMENT"];
}

尽量避免__EVENTTARGET的空间，即btnClick，希望它能解决你的问题

try to avoid space for __EVENTTARGET ie btnClick, hope it will solve your problem
