Scrollable lazy loading table in FLEX

I need to implement a lazy loading table in FLEX i.e load the table data once user starts scrolling down.

Something like this : http://livedemo.exadel.com/richfaces-demo/richfaces/scrollableDataTable.jsf?c=scrollableDataTable&tab=usage

Is there a ready made component available in FLEX to handle such requirement. If so can I have a look of that in any FL开发者_StackOverflow社区EX showcase or demo site?

Regards,

Satya

Short answer, no, there are no default components that does this behavior out of the box. However, you can code it. Since the DataGrid is data driven, you can update the dataProvider property with new data when the user scrolls to the bottom of the DataGrid. You'll need to figure that out on your own.

However, this behavior is not something I would agree with from a User Experience standpoint. I would seek another way for the user to get to the data they want, like pagination, loading all the data at once (if possible), maybe have a searching functionality or filtering. It really depends what you're trying to accomplish.

Its sometimes referred to as data-paging. James Wards has a very good demo is on Tour De Flex under Flex 4.5 for a DataGrid
