Hi, i want to share this extension that i developed for selecting page size in the paging toolbar. With this plugin you will be able to select a page size of 10, 20, 25, 30, 50 with just one click.

Is a functionallity that you can add easilly to any grid panel. The plugin also could use a cookie to read the last selected page size for that grid or if you want to keep the same size for every grid in your application just keep the same cookie name in the plugin constructor.

Here is the example:
Code:
var paging = new Ext.PagingToolbar(
        {
            pageSize: 10,
            store: store,
            displayInfo: false,
            plugins: [new Ext.ux.SlidingPager(), new Ext.ux.PagerSizeSelector(
            {
                cookieId: 'sliding'
            })]
        });




Hope you like it!
