# Infinite Scrolling with remote filtering

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.

The code is not minified, see infinite-scroll.js

A filtering UI is included which applies a remote filter and reloads the grid beginning at page one.
