I got this from some site. It can be used to know the control which caused the postback.

 public static Control GetPostBackControl(Page thePage)
    {
        Control myControl = null;
        string ctrlName = thePage.Request.Params.Get(“__EVENTTARGET”);
        if (((ctrlName != null) & (ctrlName != string.Empty)))
        {
            myControl = thePage.FindControl(ctrlName);
        }
        else
        {
            foreach (string Item in thePage.Request.Form)
            {
                Control c = thePage.FindControl(Item);
                if (((c) is System.Web.UI.WebControls.Button))
                {
                    myControl = c;
                }
            }

        }
        return myControl;
    }

If we register controls in the web.config, we don’t have to register the control on each page. This is useful, if we have to use the same control on several pages.
