Thank You Michael!! It really didn't hit me, to oversimplify my original design like that...
Since I am a pretty experienced programmer, I immediately jumped into the more advanced methods of performing this type of task - I had written custom classes, one for the itemRenderer and one for the itemEditor - and I had lots of code/listeners setup to react to the proper events. Specifically, the DataGrid_ItemEditEnd event - which is used extensively for this type of thing. My guess, is that I got things so over complicated, that I was unable to track down what the true problem was. I will use your example though, and then re-write all my Classes, so it performs the exact same functions. Hopefully, I will then get it to work MY way. There is absolutely nothing wrong with your methods - in fact, I wouldn't have been able to figure it out without your help - BUT, I write code in a very specific way, and I LOVE writing Packages and Classes - it keeps things so nice and tight - not to mention, the reusability factor... Well, thanks again - I truly appreciate your help on this :) Mike -----Original Message----- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Michael Labriola Sent: Monday, October 16, 2006 4:47 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: ComboBox itemEditor example inside of DataGrid??
