Another problem: ITEM_EDIT_END not always works well (for me…)
I use ITEM_FOCUS_OUT and it always WORKS!

Great hack. I persuaded same solution (with two event handlers) but I constantly get new value for both events. I didn’t experimented with even handler’s priority.
Thanks again!

The perfect hack! Who would have dreamed you have to set priority quite low to get the post-edit value? Paul saved us from more grueling hours of wasted time, because Adobe does not explain these basic things, nor make them easy.

Hello,

I have some problem events in datagrid flex 3.
The main goal is to create new row when user finish editing the cell and hits the enter key.

The problem is that for:
-click on new row with mouse
or
-hitting the enter key from keyboard

is the same event reason: “newRow”

I “ask” a google for the solution but without luck.

First I tried to add an event listener to KeyboardEvent.KEY_UP, and it is working for each key, except the ENTER (method for that listener is called after the editing).

Can you please help me how to distinguish mouse click on edit end and ENTER from keyboard.

Thanx in advance,
Ognjen

I have been researching this exact problem for the last couple of hours. I have tried all of your “doesn’t work” ideas, including looking at the itemEditorInstance property. When I found your article, I breathed a sigh or relieve. Thanks.

Hi Everyone,
As Tarun and Brian said that sometimes the value is not updated, I also sometimes get the same problem. Any Clues???

As said I am also facing the same problem that sometimes the underlying collection doesn‚Äôt seem to get updated. “It seems like the edit doesn‚Äôt take hold. I‚Äôm not sure if the ITEM_EDIT_END event is thrown or not, but the collection itself is not updated. In fact, if I tab around the DataGrid cells, sometimes the old value seems to appear in a cell I just edited.”

Has anyone else also faced the same problem and any workarounds for this?

Hey Paul, thanks for this great article - it really got my gear spinning and I learned how the sequence of events fire in the DataGrid.

I came up with another method of handling DataGrid updates which involves listening to the dataProvider instead. If you want to take a look, I posted an article here: http://www.verysimple.com/blog/2008/09/10/handling-data-updates-with-the-flex-as3-datagrid/

No offense to BuffDog up there, but for a boolean checkbox value, if it has changed, you always know the previous value without having to look. It is always (always) simply the opposite of the current value.

Hope you didn’t spend too long figuring that out…
