You can get the control which caused postback as below.

protected void Page_Load(object sender, EventArgs e)
            if (IsPostBack)
                Control c = null;

                string controlName = Page.Request.Params.Get("__EVENTTARGET");

                if (!String.IsNullOrEmpty(ctrlName))
                    c = page.FindControl(ctrlName);
