I am coming from the FoxPro world where its form designer supported a
"Builder" hook.

With this hook we can "select" multiple controls, and then right click to
invoke our custom builder.  In that builder, we are setting multiple
properties and do other operations like build tables (add new fields) based
on the properties you set as a group in our builder (the builder displays a
grid control that allows us to easily set the desired properties on all of
the selected controls).

Any ideas?

Thanks.  Bob
