* 2)DateTime        日历控件
*
* DateTime调用方法：
* 在编辑列中加属性  formatter: JqGridFormatCell.ToDateTime

* PopupDialog调用方法：
*   1.给编辑列加属性
*     formatter: JqGridFormatCell.ToPopupDialog ,
*     formatoptions: { UserControl: "<%=ucAirline.ClientID %>" }
*
*   2.页面最下方添加以下代码 (将弹框返回值赋给编辑列)
$("#<%=ucAirline.ClientID %>_datapicker").DataPicker("option", "callback", function (text, value) {
JqGridFormatCell.SetValue(text);
});
注：弹出框用户控件(UCAirlinePopupDialog.ascx)需自行引用至页面，并将其隐藏.
