There are a few ways to do this. One is to assign a different onclick event to each button. Another, shown here, is to have one onclick event that checks the ID of the button firing the event.

Assuming this usercontrol (ASP.Net - C#):

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="Controls_WebUserControl" %>
<asp:ImageButton ID="ImageButton1" runat="server" 
    ImageUrl="~/images/buton1.gif" onclick="ImageButton_Click" />
<asp:ImageButton ID="ImageButton2" runat="server" 
    ImageUrl="~/images/buton2.gif" onclick="ImageButton_Click"/>
<asp:ImageButton ID="ImageButton3" runat="server" 
    ImageUrl="~/images/buton3.gif" onclick="ImageButton_Click"/>

Open in new window

Code behind:

using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Controls_WebUserControl : UserControl
{
    protected void ImageButton_Click(object sender, ImageClickEventArgs e)
    {
        var button = (Button) sender;

        if (button.ID == ImageButton1.ID)
        {
            // handle Button1
        }
        else if (button.ID == ImageButton2.ID)
        {
            // handle Button2
        }
        else if (button.ID == ImageButton3.ID)
        {
            // handle Button3
        }
    }
}
