>Interesting! I just added a field from INVDTAIL to the form as a text box and set its ControlSource to INVDTAIL.ItemCode (same source as grid's column 1). I CAN edit this field. I also had added a ThisForm.PageFrame1.Page1.Details.refresh to the valid snippet of this text - and indeed the grid refreshes. PLUS, I can edit records in the grid. BUT, if I remove the text box field from the form/page, I go back to not being able to edit in the grid. We're close here, I can smell it :) But I'm not sure what to check next?

Say wha'?!!!

So this suggests that the table is editable but the grid is not. However, you say with the textbox ytou can also edit the fields in the grid. You can EDIT the field in the grid but when you save (and refresh) does the change remain permanent or revert?

You HAVE checked the complete drill-down of grid - column - textbox for .ReadOnly ?

Curiouser and curiouser.
