# Buffer Grid Example

This example customizes the grid view to do bufferred rendering of the cells of just the visible rows in the grid. This results in a much smaller DOM structure and substantially improves performance of resizing, forceFit, autoExpandColumn and other layout and DOM manipulation features in a large grid. The smaller DOM structure can also help to improve the overall performance of your Ext application.
While this example works perfectly, this is completely experimental and only a subset of standard grid features are available. It might need slight customizing for your application needs.

To use this example, be sure to add the following JS file: BufferView.js

This grid uses a ScriptTagProxy to fetch cross-domain remote data (from the Ext forums).

Note that the js is not minified so it is readable. See buffer.js.
