Here is my store & grid

 var store = Ext.create('Ext.data.Store', {
     autoLoad: true,
     fields: [{
         name: 'date',
         type: 'string'
     }, {
         name: 'emailID',
         type: 'string'
     }, {
         name: 'name',
         type: 'string'
     }],
     pageSize: 10, // items per page
     id: 'date',
     proxy: {
         method: 'GET',
         url: 'rest/helloworld/submit',
         noCache: false,
         type: 'ajax',
         root: 'result',
         totalProperty: 'totalcount'
     }
 });

 // specify segment of data you want to load using params
 store.load({
     params: {
         start: 0,
         limit: 10
     }
 });

 var grid = Ext.create('Ext.grid.Panel', {
     title: 'Result',
     store: store,
     columns: [{
         header: 'Name',
         dataIndex: 'name'
     }, {
         header: 'Email',
         dataIndex: 'emailID',
         flex: 1
     }, {
         header: 'Date',
         dataIndex: 'date'
     }],
     width: 400,

     dockedItems: [{
         xtype: 'pagingtoolbar',
         store: store,
         dock: 'bottom',
         displayInfo: true
     }],
     renderTo: Ext.getBody()
 });

但它在网格上不可见。

请帮忙

您需要定义一个阅读器:

reader: {
    type: 'json',
    rootProperty: 'result',
    totalProperty: 'totalcount'
}
