如何更新dojox.Grid以显示最新数据？dojo datagrid和itemfilereadstore

起初，我创建的空店，然后我改变了数据包含的东西，创建新的数据存储与新的数据，然后将数据存储格设置为新店。

在大多数示例中，人们在初始化商店时使用url而不是数据。

那么如何更新网格以显示最新的商店？

// Use empty grid, 
var emptyData = { identifier: "UID_T", label: "UID_T", items: [] }; 
var lgaNameSelectionStore = new dojo.data.ItemFileReadStore({data: emptyData}); 

var lgaNameGridLayout = [ 
     {name : "<span title='Agency'>Agency</span>", field : "AGENCY", width : "7em"}, 
     {name : "<span title='Project Description'>Project Description</span>", field : "ProjectDes", width : "20em"}, 
     {name : "<span title='Description'>Description</span>", field : "CTPPD_DESC", width : "12em", }, 

    ]; 

var lgaNameContainer = new dijit.layout.BorderContainer({  
      style: "width: 100%; height: 100%", 
      gutters: false, 
      design: "headline" 
    },"lgawinuid"); 

lgaNameGrid = new dojox.grid.DataGrid({ 
     store: lgaNameSelectionStore, 
     region: "center", 
     structure: lgaNameGridLayout, 
     selectionMode: "none", 
     noDataMessage: "No results found." 
    }); 

lgaNameContainer.addChild(lgaNameGrid); 
lgaNameContainer.startup(); 


//data is changed, so need to update the grid 
var data3 = { identifier: "UID_T", label: "UID_T", items: [{"UID_T" : "I333","AGENCY" : "RTA","CTPPD_DESC" : "M5","ProjectDes" : "Filtration","location" : ""}]}; 

lgaNameSelectionStore = new dojo.data.ItemFileReadStore({data: data3}); 
lgaNameGrid.setStore(lgaNameSelectionStore);

电网应该更新，当您用新的数据存储调用'setStore'。我认为你的代码是正确的。你的代码有什么问题？网格没有更新？ – 2010-05-20 02:27:18

是的，网格没有更新。 – portoalet 2010-05-20 05:09:25

的问题是在这里：

lgaNameSelectionStore = new dojo.data.ItemFileReadStore({data: data3});

你不能添加新的数据ItemFileReadStore（仅用于读），必须使用ItemFileWriteStore
