Saving datagrids

Pete. Everyone...


The DG is in a substack of a mainstack splash screen. There is a field in that substack as well. A button loads a random number into each. Or tries to, anyway. The field gets a new number, the DG does not budge. The IDE stack works fine. The DG template is attached as a stackFile before I make the standalone.


I am talking about saving between standalone sessions. If I change the data, close the standalone, and re-open, the new field data is there. Great. The DG never changed in the first place, so I may have mis-stated the problem. It may not be a matter of saving the DG at all. If I cannot change the DG data  in the first place, who could say?


This all started from a forum question about saving a DG. He could not. I tried a test, and I cannot even modify the DG contents. Did I mention that the field saves just fine?

Are we talking about saving data between runs of the standalone or just 
re-opening the stack in the same run of the standalone?  As other have pointed 
out, there is no way to save data between runs of a standalone without the usual 
workaround they mentioned.  But I think datagrids have a "persistant Data" 
property that affects whether the data in them is saved when the stack they are 
in is closed and then re-opened in the same run.

Not sure what's happening with your follow up email about the dg not being 
populated, that sounds very weird.
