Ext JS 4's brand new grid supports infinite scrolling, which enables you to load any number of records into a grid without paging.
+The new grid uses a virtualized scrolling system to handle potentially infinite data sets without any impact on client side performance.
+This example illustrates loading of all the records up front and buffering the rendering. Take a look at the Forum example which illustrates dynamically loading data from a remote source.
+The code is not minified, see buffer-grid.js
