grid中增加checkbox列，加载的时候选中已经存在的列 

grid增加checkbox列
 1         Ext.apply(this, {
 2             id: "userrolegrid",
 3             width: 700,
 4             height: 500,
 5             selType: 'rowmodel',
 6             selModel: new Ext.selection.CheckboxModel(),//复选框模板
 7             columns: [
 8                 { text: '角色名称', dataIndex: 'NAME', flex: 1, align: 'center' }
 9             ],
10             store: Ext.create('App.store.RoleStore'),
11             buttons: [{
12                 action: 'userrole_save_button',
13                 iconCls: 'icon-submmit',
14                 text: '确定'
15             }, {
16                 action: 'userrole_cancel_button',
17                 iconCls: 'icon-remove',
18                 text: '取消'
19             }]
20         });

 



加载的时候选中已经存在的列，在store里面监听load事件
 1 listeners: {
 2         load: function (store, opration) {
 3             var userID = Ext.getCmp('usergrid').getSelectionModel().getSelection()[0].data.ID;
 4             var sm = Ext.getCmp('userrolegrid').getSelectionModel();
 5             var records = [];//存放选中记录  
 6             Ext.Ajax.request({
 7                 url: '/OLXD/COC/User/GetListByUserID',
 8                 method: 'post',
 9                 params: {
10                     userID: userID,
11                 },
12                 success: function (response, options) {
13                     var arr = Ext.decode(response.responseText);
14                     for (var i = 0; i < arr.length; i++) {
15                         records.push(store.findRecord('ID', arr[i].ROLE_ID));
16                     }
17                     sm.select(records);//执行选中记录  
18                 },
19                 failure: function () {
20                     Ext.msg.show('提示', '调用出错');
21                 }
22             })
23         }
24     }
