我正在开发使用C＃一个asp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 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 }
