                function CloseMenus(e) {
                    if (e == '') { return false; }
                    var GridView1 = document.getElementById(e);
                    var TR_Grid = GridView1.getElementsByTagName("tr")
                    for (i = 1; i < TR_Grid.length; i++) {
                        TR_Grid[i].style.display = "none";
                    }
                }
