Dojo 1.7 datagrid根据隐藏列中的文本更改行颜色

Question

我正在使用增强的网格来显示消息。网格我定义如下，

function loadgrid(str)
{
        require(['dojo/_base/lang', 'dojox/grid/EnhancedGrid', 'dojo/data/ItemFileWriteStore','dojox/grid/enhanced/plugins/Pagination', 'dojo/dom', 'dojo/domReady!'],
        function(lang, EnhancedGrid, ItemFileWriteStore, dom,Pagination)
        {
          var data = 
            {
                identifier: "id",
                items: []
            };
            var data_list =  JSON.parse(str);
             for(var i = 0, l = data_list.length; i < l; i++)
            {
                data.items.push(lang.mixin({ id: i+1 }, data_list[i]));
            }
        var store = new ItemFileWriteStore({data: data});
        if(!document.getElementById("grid"))
        {
             var layout = [[
                          {'name': 'S.No', 'field': 'id', 'width': '5%'},
                          {'name': 'MsgId', 'field': 'msgId', 'width': '1%'},
                          {'name': 'Status', 'field': 'status', 'width': '1%'},
                          {'name': 'Sender', 'field': 'sender', 'width': '15%'},
                          {'name': 'Receiver', 'field': 'rec', 'width': '15%'},
                          {'name': 'Message', 'field': 'msg', 'width': '35%'},
                          {'name': 'Time', 'field': 'time', 'width': '20%'},

                        ]];
            var grid = new dojox.grid.EnhancedGrid(
            {
                id: 'grid',
                store: store,
                structure: layout,
                rowSelector: '20px',
                plugins: {
                    pagination: {
                        pageSizes: ["5","10","25", "50", "100", "All"],
                        description: true,
                        sizeSwitch: true,
                        pageStepper: true,
                        gotoButton: true,
                                /*page step to be displayed*/
                        maxPageStep: 4,
                                /*position of the pagination bar*/
                        position: "bottom"
                    }
                  }         
            },document.createElement('div'));
            grid.layout.setColumnVisibility(1,false);
            grid.layout.setColumnVisibility(2,false);
            grid.placeAt("gridDiv");
            grid.startup();
        }
        else
        {
            var grid = dijit.registry.byId("grid");
            grid.setStore(store);
        }
     });

}

该str是包含JSON对象的字符串。在这里我想改变行的颜色，以区分读取和未读消息。我怎样才能实现这一目标？

最后我得到了解决方案

function loadgrid(str)
{
        require(['dojo/_base/lang', 'dojox/grid/EnhancedGrid', 'dojo/data/ItemFileWriteStore','dojox/grid/enhanced/plugins/Pagination', 'dojo/dom', 'dojo/domReady!'],
        function(lang, EnhancedGrid, ItemFileWriteStore, dom,Pagination)
        {
          var data = 
            {
                identifier: "id",
                items: []
            };
            var data_list =  JSON.parse(str);
             for(var i = 0, l = data_list.length; i < l; i++)
            {
                data.items.push(lang.mixin({ id: i+1 }, data_list[i]));
            }
        var store = new ItemFileWriteStore({data: data});
        if(!document.getElementById("grid"))
        {

            grid.layout.setColumnVisibility(1,false);
