Are you setting the readOnly Property of the Grid, or for the table in the data Environment?

I just did the following:

Created a form.
Dropped the a base class grid on it.
Set columnCount to 2
Opened a table in the dataEnvironment
Set the Grid's RecordSource property to the table using the drop down list.
Set the Grid's readOnly property to .T.

Tested it, could not edit the data.

modi'd the form. Set the grid's readOnly to .F., and set the the Cursor object for the table in the Data Environment's readOnly property to .T.

Tested it, and COULD edit the data.

I am not trying to be argumentative, I just can't get the behaviour you are describing.
