Rather than using the business object on the main form, I recommend you do the following:

1. In the Click handler for the Edit button, get the PK of the grid's current row (you can get this by calling the mmDataGrid GetCurrentRowPK method.

2. Instantiate your popup form and pass the PK in the constructor of the form

3. Add a new instance of the business object to your popup form and create a new method (if you don't already have one) that can accept the PK and retrieve the desired record.
