Welcome to Flex BitmapGrid.
This grid was created to fulfil a simple need for Outswitch.com, super fast horizontal and vertical scrolling with unlimited number of rows and columns.
The trick is to Draw only the visible rows and columns on a bitmap canvas.
It uses only one ItemRenderer to draw all the cells.
We use it for a calendar with 365 columns and 500 Rows. It never hangs, renders in less than a second and scrolls like a charm.
Anyhow please do keep in mind this was created to just draw cells, so there not much grid functionality there... i'm adding code on a need to have basis. If you wish to contribute, you're more than welcome.
