Question

在一栏中,我有一顿的网格。我在电网概览中加上后面的代码。我用这条线附上我的点击事件:

cmd1.OnClientClick +=new eventHandler(cmd1_Click);

Now every time I click that button, it gives me a run time error and breaks at System.EventHandler of <input type="submit" name="grvList$ctl02$ctl05" value="Add" onclick="System.EventHandler;" />

任何人都没有遇到这一问题。

由于用户1090190在评论中写道,onclick(产生于OnClientClick/code>) 已在作为 Java本的网络浏览器上执行。



The += in this case is calling ToString() on the new EventHandler object that is created which results in the string "System.EventHandler". (The += expression expands to cmd1.OnClientClick = cmd1.OnClientClick + (new EventHandler(cmd1_Click)); and the implicit conversion happens because OnClientClick is typed as a string.)

可能的话(注no.Client):

cmd1.Click += new EventHandler(cmd1_Click)


或者,更简单地说(don问我,为什么汽车装饰总是“瓦解”):

cmd1.Click += cmd1_Click;


确保酌情设立each后台。

幸福 co。
