子頁面關閉時重新整理父頁面 javascript + asp.net

父視窗彈出子視窗的 button處理事件:

       private void butDeta_Click(object sender, System.EventArgs e)
        {
            Response.Write("<script>window.open('CangkuDetaList.aspx?strMateNo="+ txtMateNo.Text +"&strWaretype="+ ddlWareType.SelectedValue +"','new1','width=750,height=400,toolbar=0,scrollbars=2,top=200,left=200');</script>");
        }

父視窗html代碼添加如下javascript代碼:function refresh()
{
    this.location = this.location;
}

子視窗關閉視窗的 button處理事件:        private void imgbtnBack_Click(object sender, System.Web.UI.ImageClickEventArgs e)
        {
            Response.Write("<script>window.opener.refresh();window.opener=null;window.close();</script>");       
        }
