>>I have a Grid whose Recordsource is a Cursor produced via a query. One of the fields is a logical field which is displayed using a checkbox. It all displays perfectly, but it won't allow me to edit the checkboxes. It says the field is 'Read Only'. I want to allow changes to the logical field via the checkboxes. Is there a way to do this? While the other columns of the Grid are marked ReadOnly, this column is definitely not.

But, if you only want to edit the results of your query and then do your own thing with them, you can use this little trick:

>USE IN temp1

Thanks Erik, it worked perfectly when first creating the cursor. I had a problem when I was requerying the data when the cursor was already in memory, as it showed that the alias name was already in use. I got around that by checking if the editable cursor was USED(), then if so, copying the temp cursor to an array, zapping the editable cursor and appending the array. That meant that the grid could then be refreshed without breaking the link to its datasource!

Thanks again, it was a great help
