<h1>Array Grid with Local Paging and Remote Reloading</h1>
<p>Demonstrates how to create a grid from Array data with Local Paging and Remote Reloading.</p>
<p>
Notice <b>Last Updated</b> column is revised with a new server-side DateTime stamp when the GridPanel "Refresh" button is clicked.<br />
This demonstrates that when the GridPanel is refreshed, the Data is requested again from the server via a DirectEvent, but the Paging and Sorting is done completely client-side in the browser.
