(DataGrid) is there a message when the user has edited a cell ?

[Andre.Bisseret]

Bonjour TheSlug,

Great help and learning for me!

I just played with your demo stack! Magnifique ;-))

Thank you very much for your time and for sharing your high knowledge  
about data grid! very much appreciated.
Seems you are the best as for Data Grid (after Trevor ;-O)))

I am a bit pigheaded so I tried your solution 1 in a data grid without  
template stack (in a new stack, a copy of group "DataGrid" of group  
"Templates" of stack "revDataGridLibrary").
I put the 3 handlers: "getprop uSumOfColumn[pColumn]", "on doSum" and  
"on CloseFieldEditor pFieldEditor" into the script of the data grid.

And all is working nicely :-)
So, seems I still can keep my current data grids in the app. I am  
making.

Thanks again and have a nice week-end

André

AH! OK
