A lot of people have been asking for an example of how to use SlickGrid with remote data stores. I've just added a new sample page that does just that:
http://slickgrid.googlecode.com/svn/trunk/examples/example6-ajax-loading.html The page will pull all Apple-related stories from Digg.com and display them in a grid. I've also added an option to set a user-defined row height (something I've meant to do for a long time). Check it out at http://code.google.com/p/slickgrid/
