data grid by hand doesn't create a data grid templates' substack

[Andre.Bisseret]

Bonjour,

When one drags a data grid from Tools one gets a data grid templates  
substack nnn

But if one creates a datagrid with:
------
copy group "DataGrid" of group "Templates" of stack  
"revDataGridLibrary" to card 1 of this stack
put it into theDataGridRef
------
  there is not such a substack.

then I suppose that the data grid will work only in the IDE? (being  
dependent of the revDataGridLibrary)

Seems I am missing something here

Could be that In the lesson, I don't well understand the following:
----------------
set the dgProp["row template"] of theDataGridRef to the long id of  
group "MyRowTemplate" of stack
"MyStack"
You should probably create this ahead of time using the IDE. For  
example, you could create a data
grid and then delete it while leaving the row template behind (it will  
exist on a card in "Data Grid
Templates xxx" stack).
--------------
With what should I replace "MyRowTemplate"?

I am not in a hurry about that but would like to better understand ;-))

Best regards from Grenoble
