using Ext.PagingToolbar plugin, we can implement pagination to a grid panel

syntax:

new Ext.PagingToolbar({

pageSize: 25,

store: store,

displayInfo: true,

displayMsg: 'Displaying topics {0} - {1} of {2}',

emptyMsg: "No topics to display",

})

// trigger the data store load

store.load({params:{start:0, limit:25}});
