Lazy loading dataview with buffering / caching

[shodan_uk]

Hey guys,

I'm looking to build a dataview that displays 10 items at a time from a "buffer" of 50 that lazy loads the next / previous 10 items when the user scrolls to the bottom or top of the list. I'm trying to keep down the number of http calls (hence the buffering) but I also want to avoid having too many list items on screen (for performance reasons) or too many data items in memory (there could be 1000s).

*edit* I'm aware of the ListPaging plugin, however it doesn't quite fit my requirements. I'm guessing I may need to extend it.

Any advice on how to achieve the above would be gratefully received

Cheers,
Terry

This currently is not support out of the box but in 2.1.0 we are adding support for infinite list that will do this.

Thanks for the info.

Any thoughts or suggestions on how do it with 2.0.2?

Awesome news that Sencha is making an infinite list

In the meantime you can have a look at the ext.ux.bufferedlist that was ported to Sencha Touch 2.0.
Take a look at this thread:
http://www.sencha.com/forum/showthre...eredList/page9

And the source code can be found on
https://github.com/robertklep/buffer...sencha-touch-2

I'm currently using it to display lists of over 10000 items and it works fluently.
