求一个完整的ext grid分页源码demo(.net的)

Question

RTRT,顺便帮我看看如下代码为什么实现起来有问题呢
<script type="text/javascript">
Ext.onReady(function(){
   var sm = new Ext.grid.CheckboxSelectionModel();
   var cm = new Ext.grid.ColumnModel([
         new Ext.grid.RowNumberer(),
         sm,
        {header:'编号',dataIndex:'id',sortable:true},
        {header:'名称',dataIndex:'name'},
        {header:'日期',dataIndex:'date'},
        {header:'描述',dataIndex:'descn'}
    ]);    var data = [
        ['1','name1','2008-11-10','descn1'],
        ['2','name2','2008-11-08','descn2'],
        ['3','name3','2008-11-11','descn3'],
        ['4','name4','2008-11-12','descn4'],
        ['5','name5','2007-11-11','descn5'],
        ['4','name4','2008-11-12','descn4'],
        ['4','name4','2008-11-12','descn4'],
        ['4','name4','2008-11-12','descn4']
    ];    var ds = new Ext.data.Store({
        proxy: new Ext.data.MemoryProxy(data),
        reader: new Ext.data.ArrayReader({}, [
            {name: 'id'},
            {name: 'name'},
            {name: 'descn'}
        ]),
        remoteSort: true
    });  
 ds.load({params:{start:0, limit:2}});
 
   var grid = new Ext.grid.GridPanel({
    el: 'grid',
    ds: ds,
    cm: cm,
    sm:sm,
    bbar: new Ext.PagingToolbar({
            pageSize: 2,
            store: ds,
            displayInfo: true,
            displayMsg: "显示第 {0} 条到 {1} 条记录，一共 {2} 条",
            emptyMsg: "没有记录"
        })
       
});
    grid.render();            
})</script>          

Answer 1

var ds = new Ext.data.Store({
        proxy: new Ext.data.MemoryProxy(data),
        reader: new Ext.data.ArrayReader({}, [
            {name: 'id'},
            {name: 'name'},
            {name: 'descn'}
        ]),
        remoteSort: true
    });  

Answer 2

没注意检查,因为修改过数据源,这个地方还没改过来就发上来了,不是这里的问题哈~~~
这里改成{name: 'id'},
{name: 'name'},
{name: 'date'},
{name: 'descn'}
依然没办法实现换页,而且ds.load({params:{start:0, limit:2}});
还需要放在最后才能正常显示分页栏,可是换页的页码数是乱的,页面也不会变动
