How to get a same data grid on each card?

[Andre.Bisseret]

Bonjour Trevor (and all)

I have an old app I built in HC, then I converted in Rev. and that I  
am using quite a lot.
Now, I am transforming it in a true Rev app ;-))

On each card on a stack I have a background including, among other  
objects, a table whose columns are made with grouped scrolling fields  
(an old solution ;-)

I would like to replace this with a data grid.

My first attempt was to put a data grid in the background, expecting I  
could populate it with specific data on each card.

But seems this is not possible. When doing "new card", I get a data  
grid on the new card,
- without the columns headers, which is not a big issue,
- but when I populate the data grid on the new card the data grid on  
the previous one is emptied

So I understand that in fact,  the data grid which is replicated on  
each card can be populated only on the current card.

In other word including a data grid in a group with background  
behavior set to true seems not a good idea. I found an answer from  
Trevor in the archives that seems to confirm that.
-------------
"If you want to have different data on each card (I assume you are  
sharing the data grid across cards) then you would need to:
a) Load the data into the data grid on open card each time a card opens.
b) Create separate data grids for each card."
-------------
In my case, I can't do a), I have to do b)

Then, I red the lesson which explains how to create a data grid  
through script.

But I am trying to avoid re-defining for each new card, the properties  
of the data grid (columns, their names and labels, their width etc.

So my later trial is as follow :

I create a data grid "dataGrid" (with all needed properties defined)  
on the first card of the stack.
I don"t include it in the background of this first card

Then, when I create a new card I do :

   copy grp "DataGrid" of cd 1 of this stack
    paste
    set the dgText of grp "DataGrid" to empty

So I get a data grid (with the same name) on each new card ready to be  
specifically populated for this card.

Seems to work well :-)

Trevor, is this a good way to go or are there some warning against it?

Thanks a lot in advance for any advice

Heureuse année 2010
