[flexcoders] Re: ComboBox itemEditor example inside of DataGrid??

2006-10-16 Thread Michael Labriola 
Mike,

I apologize in advance if this is now what you are asking, but, have
you looked at the editorDataField property?

If this isn't what you are looking for, I can post an example of a
ComboBox renderer in a DataGrid.

 I've been able to get this to work in the most simple of examples - BUT,
 here is what I need to do that may be considered unique in my case
 (although, not at all uncommon in most other typical programming
 environments).
 
 In my case, my OrderDetails DataGrid contains a 'ProductID' Field from
 the 'Products' Table.  It would be redundant to create an additional
 field called ProductName within my OrderDetails Table - since it
 already exists in my Products Table.
 
 I know for a fact, that there is a way for the ComboBox itemEditor, to
 display the Label property of the Product (in this case, ProductName),
 but still leave intact, the Numeric Data property of the Product (in
 this case, ProductID) - so that part gets written back to the DataBase.
 
 I am having a TERRIBLE time, finding an example of how to have the
 ComboBox display one thing, but set the value in the DataGrid, to some
 OTHER thing - 
 
 Could any of you help me in this regard?
 
 Thanks in advance,
 
 Mike

RE: [flexcoders] Re: ComboBox itemEditor example inside of DataGrid??

2006-10-16 Thread Mike Anderson 
Yes, I've been exploring that property all day long -

There must be something else I am doing wrong here -

So with that said, YES, if you could please post an example, I'd be
grateful -

Right now, I have a ComboBox Component I created - and I am binding the
dataProvider property of it, to my Apps model.produstList property.
And yes, this is a Cairngorm based application - but I don't think this
should affect anything.

My OrderDetails DataGrid, is populated using ValueObjects - and the
ProductID Column initially displays only numbers.  Of course, this is
great - since that column should only display Integer values anyway
(this is previous to applying the itemRenderer and itemEditor).

BUT, now that I want the ProductName value to display all the time, do
I also need to declare an itemRenderer as well?  I ask this because,
only the ComboBox populated with ProductID and ProductName, contains the
associated information - where the underlying ProductID value contained
behind the scenes, drives what is displayed to the user.  The issue is
though, the itemEditor only becomes active, whenever the Cell is active
correct?

Well, bottom line is, I am so frazzled by this incident, that I am sick
and tired of racking my brain trying to figure this out.  I wasted 2
incredibly valuable days on this darn problem, with absolutely nothing
to show for it.

If you could please post some code and examples, I would be grateful.

Thanks in advance,

Mike

RE: [flexcoders] Re: ComboBox itemEditor example inside of DataGrid??

2006-10-16 Thread Mike Anderson 
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

A custom class is the right way. It is just a lot harder to post.
