It’s the morning of April 1st, I am looking at my editable sub-grid, and I start panicking. Because, apparently, it’s not working – I can’t edit anything at all.
I tried pretty much everything (re-enabling the grid, changing the view, updating control settings in different places, looking in the community forums).. Nothing worked.
And, then, I realized that the parent record (for which Dynamics was displaying that sub-grid) was read-only:
Well, sub-grids, you have certainly made fun of me, but I’ll tell you this: I can still edit those related records if I just open them separately (as in, if I double-click any of the sub-grid rows), so I’ll be the one who laughs last!
