[Data grid] an inert data grid ; how is it possible ?

[Andre.Bisseret]

Bonjour,

I have a data grid in a substack. It was running well for weeks up to  
yesterday evening.
But, this morning, it was as "disabled" !

Impossible to select a line, to sort any column, to get the dgText of  
it, to add a line to it, and so on !

Fortunately, there was not too much work to replaced it by a brand new  
one which is working nicely,

I would like to understand what  I could have done inadvertently to  
get such a broken data grid
and then, what I should have done to fix it ?

Thanks a lot in advance for any advice

Best regards from Grenoble

André
