    jydhwdInfoStore.load({ params: {start:0,limit:pageSize} });----------------------------------------------------------------------
   var Publishgrid = new Ext.grid.GridPanel({

        }),
        bbar: new Ext.PagingToolbar({
            store: jydhwdInfoStore,
            pageSize: pageSize,
            displayInfo: true,
            displayMsg: '当前记录 {0} -- {1} 条共 {2} 条记录',

            refreshText: "刷新",
            lastText: "最后页",
            firstText: "第一页",
            beforePageText: "当前页",
            afterPageText: "共{0}页"        }),
去找个plugin
直接用
bbar: new Ext.PagingToolbar({
                pageSize: 30,
                store: store,
                displayInfo: true,
                displayMsg: '当前:{0} - {1}, 共: {2}条',
                emptyMsg: '没有记录',
                plugins: [new Ext.ux.plugin.PageSizeCombo(), new Ext.ux.ProgressBarPager({ defaultText: '加载中...' })]
            })
你确定load方法在grid渲染之后?
