There's a CANCELLED reason for Esc. I'm kinda lost right now. What do you want to happen on -tabbing to next column -enter going to next row -clicking on another cell in a different row -scrolling -clicking outside DG -esc cancelling edit Which cases aren't working?

One issue (so far) with this is that if you Tab with an invalid value (focus is lost and regained), then follow up with an Esc, the committed value will be the invalid one. I might be able to live with this. If I call preventDefault in the OTHER case, I don't have that issue, but then the editor regains focus but without the current (invalid) value.

I don't know if there's a bug, per se. As I mentioned in my first post, I only had an issue when losing focus to something outside the grid. I may have a workable solution which is hopefully not too ugly: - on itemEditEnd, call preventDefault, and re-activate the editor using editedItemPosition - in the editor, override setFocus and call the validator I haven't tested this with scrolling.

I just took a look at the code. When tabbing from one cell to another, preventDefault() on itemEditEnd should keep the editor alive. If you put together a small test case I can try to see why it doesn't work. ________________________________ From: flexcoders@yahoogroups.com <mailto:flexcoders@yahoogroups.com> [mailto:flexcoders@yahoogroups.com <mailto:flexcoders@yahoogroups.com> ] On Behalf Of Richard Rodseth Sent: Thursday, November 29, 2007 10:52 AM To: flexcoders@yahoogroups.com <mailto:flexcoders@yahoogroups.com> Subject: Re: [flexcoders] itemEditEnd preventDefault And if I omit preventDefault, the invalid value remains, but the red focus ring turns blue. I've also established that setting editedItemPosition creates a new item editor (as I would expect), so I can't store and access a "valid" flag in the item editor component. Is there some other way to prevent an invalid field from losing focus? Or to restart the edit with the invalid value and have it re-validate?

I wish to prevent the edit from ending if the data is valid. When tabbing, the following works in column one, but not in column two (the last editable column): private function handleItemEditEnd(event : DataGridEvent) : void { if (event.itemRenderer.data.valid) { // do some stuff } else { event.preventDefault(); } Any ideas? Also, does the renderer get any access to this event? If I want to move "valid" from the data to the renderer itself, I suppose I would have to cast event.itemRenderer above to my renderer type, and call a method or access a property. Thanks.
