>Where is the best place to execute the CREATE CURSOR, in the INIT method of the form?

I would do it in the Load of the form so it's available when the grid initializes.

You can do it either way. It's probably easier to do it at design time. Set the recordsource to the name of your cursor, set the control source of the column to the cursor's fields.

You'll need to do a THISFORM.MyPage.Page2.MyGrid.Refresh()
