So what’s all the difference then….

• Superb scroll feeling… it looks just real
• We can still produce any HTML, in stead of fixed table-rows
• We now have XSLT support!!! I’m really happy with this one. It allows to have
  any xml source as dataset for the grid. Just before it gets placed into the grid for viewing, you can do some xslt magic on it. Just have a look at the source of the yahoo demo to see how it works. This demo will take the literal html of the yahoo-api and gets parsed by our own xslt.
• Auto-size. the livegrid can automatically do calculations and resizing if the grid is empty on forehand. This way your HTML page doesn’t need to know the exact row-size that will be returned by the
• In stead of keeping a set of rows in the buffer, we keep the xml-source in the buffer, and any newly loaded source is merged with the first one. For merging that is not-standard, you can specify an xpath to select the rows that should be buffered & used for display.
• And ofcourse, last but not least, the reason why I started the fork in the first place: the scrollwheel support!

The sources, demo’s etc can be found at:

• The grid’s javascript
• The most basic demo, loads html through ajax
• The serverside script that delivers the HTML for the simple demo
• The yahoo demo!
• The yahoo xslt
• the prototype script that is required

Enjoy!

Also, here’s the source for the dummy output file getrows.php wich is used at the demo

So, what does the grid expect as input….
The output should always be wrapped by <ajax-response></ajax-response>

de <ajax-response> tag CAN contain the rowcount attribute wich should indicate the number of rows in this request. If it’s not specified the grid tries to figure it out itself. It CAN also contain the totalrows attribute. If that attribute is filled (with the total dataset rowcount), it overrules the initial value set by javascript. Each row within the resultset should contain a rownum=”i” where i starts at 0 (zero) for every request….

Though, trying to implement it on my site, immediately some things started irritating me:

• No support for the mousewheel
• Your html-output needs to be serialized (ie. use <a> for <a>)
• I don’t want the page itself to define the item height by using empty rows, I want it to calculate the height as soon as the first items load
• Very strict html required (it must be a table with tr’s)
• The use of Rico.AjaxEngine: ok, so it’s a cool script and everything. But imho it’s kind of outdated and bloated (all respects though!). Prototype is being build further, the effects part of prototype has already been seperated from the core and is now maintained at script.aculo.us
  Prototype’s Ajax.updater does just as good a job as the Rico.AjaxEngine, etc.

So I forked the Rico.LiveGrid and created a version that works directly with prototype, has mousewheel support, and supports any kind of html (in theory ). I don’t have any time to setup a demo right now, but will do so soon.
