Hello Didier,
If you got some results I will be happy to see them.
Biggest problem is because Delphi doesn't support multiple inheritance and that I will need to create new TNxDBCustomEdit and then inherit other DB editors again from this component

May be I am being naive, but I would start from your components and "just" add the db_awareness layer.
I'll give it a go and let you know how this works

Hello Didier,
You will need to add same procedures to every component then You will need DataField property, DataSource and so on for DB-aware versions.
I will like to keep standard version separate from db-versions and this may be hard to archieve.

I gave it a go and seem to have a bit of a problem with updating the data once it's been entered, not sure why. I'll investigate more tomorrow but I might have to ask for some help. Would that be allright or are you too busy at present ?

Hello Didier,
You may ask and I will try to help
I suggest also that you check VCL source to see how their db-editors are made.

Boki,
I am making good progress with some components. One thing beats me though I can't figure out which event is fired when you click on an item in a tNxComboBox. it seems that I'll need to override that event to properly update the underlying field but find it difficult to follow. Can you point me in the right direction ?

Hello Didier,
I am glad to hear this I can't wait to see how it progress.
Maybe DoDropDownInput procedure is what you need. This procedure occur when you finish editing inside popup.

Boki,
I might have found a bug in tnxComboBox: Even if it is set to read Only, you can still change it's contents by selecting an item in the dropdown window.
That's blocking me to get a proper behavior in dbaware version. What do you reckon ?
I believe that
Should become
and that
Should become
And finally should'nt
become
I am not too sure about the last one, as I am getting confused between DsDropDown and dsDropDownList modes
Hope I am making sense
Didier

I am now running out of time (I have a prog to deliver on Monday morning, so need to stop playing around. I will resume work later. But probably changing a bit because the gRaph I made made me realise that by changing just tnxEdit I could have a host of object nearly completed in on swoop. ... tempting
and I'll probably work with an interface instead of adding the obects directly (not too sure yet) this way I could have only one set of objects dbaware and non-dbaware ... something the VCL cannot provide. (try to use a tdbedit w/o specifying a datasource/datafield and you'll get my meaning. if
could avoid that ... would be fantastic. but that's for another day

Hello Didier,
I was try to use interfaces for making Db-aware editors, but it may be anoying implementing same procedures for each new db-edit. Example:
TNxComboBox = class
TNxDBComboBox = class(TNxComboBox, IDBEdit);
This IDBEdit will need to have DataField and DataSource properties, and one TDataLink object need to be created too. It will be tricky definitelly, but it is possible.

I suppose you're right. That's definitely the drawback of interfaces. On the other hand it might allow constructs lile 'if not supports(idataaware) then behave like a normal nxEdit ... for example. I'll have a play asap.

Hello Didier,
I have think about this too, about implementing DataField and DataSource into TNxCustomEdit and then simply publishe these properties for db-editors. But this also may give some problems

Like what for example ?
I have a feeling that you would have to revisit some descendants. Am I right ?

Hello Didier,
I have do this with NextInspector, every item already have FieldName. So far no problems with it.
But, I am allways aware that Borland/CodeGear will not include support for DB's (TField) in some versions of Delphi/BCB.
