I don't know why it's private now, but maybe you could try looking at the findNextItemRenderer() implementation in the DataGrid.as in the B3 source and try implementing something along those lines? -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Web site design development Computer software development Software design and development Macromedia flex Software development best practice YAHOO!

[flexcoders] subclassing DataGrid in Beta 3
So, one of our requirements is to make the up/down arrow keys work in
a DataGrid that is being edited. In Beta 2, I was able to subclass
certain functions (keyDownHandler, findNextEnterItemRenderer) of the
DataGrid which were marked public at the time. Now it seems these
functions are marked private so I am unable to subclass them. Does
anyone have any ideas as to how I can achieve functionality similar to
the code below?
Thanks,
Jim
