Can you check my sample here: http://roytang.net/sandbox/DataGridSample.swf
Source at http://roytang.net/sandbox/DataGridSample.mxml When I tab starting from the textinput and all the way to the last row of the datagrid (row 14), it's still ok. But after tabbing out from row 14 the tab order becomes "trapped" in the onscreen checkboxes (and doesn't even follow them in the top-to-bottom left-to-right order) --- In flexcoders@yahoogroups.com, "Alex Harui" <[EMAIL PROTECTED]> wrote: > > tabEnabled is ignored for renderers/editors.
