in Windows form, I have Datagridview and detailview with the same binding
data manager. upon clicking the + in the navigator, the primary key field is
blank as expected, but I need to enable it for new record to let user to
fill it. On the other hand I don't want to allow change to the field for
existing record. so disable that on existing non new record. How do I do
that?


I notice the property of the fields are enabled in the form design, but
could not find any code for disable them.

Are you sure that allowing the user to fill the primary key is a good idea?
These are often left to the database and the insert statement will often
accept all fields _except_ the primary key which is often, by convention,
autogenerated.
