e.CommandArgument对于ASP按钮不起作用 [英] e.CommandArgument for asp button is not working

问题描述

我正在开发使用C＃一个asp.net应用程序。
我创建了一个.aspx页面中，并放置在页面上不同位置的四个按钮。
在服务器端，我想用只需点击一下鼠标事件所有四个按钮。

I am developing a asp.net application using C#. I created an .aspx page and placed four buttons on different locations on the page. On server side, I want to use just one click event for all four buttons.

下面是我的code：

aspx页面

<asp:Button ID="Button1" runat="server" CommandArgument="Button1" onClick = "allbuttons_Click" />
<asp:Button ID="Button2" runat="server" CommandArgument="Button2" onClick = "allbuttons_Click" />
<asp:Button ID="Button3" runat="server" CommandArgument="Button3" onClick = "allbuttons_Click" />
<asp:Button ID="Button4" runat="server" CommandArgument="Button4" onClick = "allbuttons_Click" />

CS页

protected void allbuttons_Click(object sender, EventArgs e)
{
    //Here i want to know which button is pressed
    //e.CommandArgument gives an error
}

推荐答案

@Tejs是他的意见正确的，看起来像你想是这样的：

@Tejs is correct in his comment, looks like you want something like this:

protected void allbuttons_Click(object sender, EventArgs e)
{
    var argument = ((Button)sender).CommandArgument;
}
