Editing datagrid cells

[Simon Knight]

I added a custom prop to store the name of the field being edited following a suggestion made on the Livecode forum.  I added this line to the EditValue handler in the Row Behavior script : set the cFieldName of grp "DgNotes" to pKey  -- store this for use in the custom field editor. Code in the custom field editor reads the value when it processes the key presses.

I am trying to detect a return in a specific field  on a datagrid form and so far I can either detect the return but not the name of the field (I just get the name of the field editor) or I can get the name of the field with no detection of the key press (because the keypress has gone to the field editor).
