DBLookupComboBox and DBGrid (Delphi 3)

Hi nk51,

read this article : http://www.gnomehome.demon.nl/uddf/pages/dbgrid.htm#dbgrid1

regards, Zif.

The answer you give is for a DBLookUpCombo and not for a DBLookUpCombobox...
I try to use a DBLookUpComboBox with the proposed code but with no succes.

create lookup field in your DataSet (tquery or ttable)
and add a cloumn in your DBGrid that is attached to this field

but do not forget working with lookups is slow operation slow

Can you explain the steps to do this with more details please ?

dblClick on your main dataset (tquery or tTable)
a window will popup
click btn add new field, another window will apear
adjust properties of the new field - make field lookup and adjust its properties( they are like this when adjusting properties for DBLookupCombo...)


dblClick on your DBGrid
add cloumn in the popuped window and set the field property of this column to above created field

I don't understand...Sorry. What about the DBLookupCombobox ?

the above procedure will help
DBGrid will use as InplaceEditor for such colomns (linked to lookup fields) component that has similar behavior to that of
DBLookup...

Delphi DBGrid has its own DBLookupComboBox included, you don't have to make your own ! but if you do !?!

And about Zif proposed answer about DBLookupComboBox in http://www.gnomehome.demon.nl/uddf/pages/dbgrid.htm#dbgrid1 just rename your DBLookUpComboBox component name to DBLookUpCombo1 !

Regard, Adeng.

nk51,

 here is another article if you haven't figured it out yet, with the other one.

Regards, Zif.

To velev : which above procedure ? I don't have a good english and perhaps I don't understand what you write but I don't understand your answer...

Adeng said that "Delphi DBGrid has its own DBLookupComboBox included, you don't have to make your own !".
Is it true ? Because It's better fo me.
How to use the own DBLookupComboBox of e DBGrid?
Thanx.

hehe, forgot the article :

topic from Delumpa (writer of article)

Note: Some of you old hats at Delphi might immediately exclaim, "What's the use of this article? In Delphi 3, we have the capability of specifying a cell in a DBGrid to be a drop-down edit." Well, that's the thing, isn't it? You have to fill in the values of the Items property yourself. What I'm suggesting here is adding a TDBLookupComboBox that will enable you to look up information from another data source. This isn't available in ANY version of Delphi.
By the way, this isn't my original idea, and in fact, the technique has been around since Delphi 1. But it's valid and applicable to Delphi 3.


Regards, Zif.

Just what I needed.
The latest ZifNab's comment about the article : http://www.delumpa.com/tips/comps/comps10.htm 
said the same thing.
Thanx.
