OK you found a solution to the first problem.
The dropdown choices are static. In most cases this works well because most
dropdowns use static list - like US states. But in this case you have to
update the dropdown. The way I have been successful is to create a new class
for my dropdowns. In the new class I override the update method like below.
So when an update occurs my dropdown is updated.
class CourseDropDown(dabo.ui.dDropdownList):
def update(self):
self.removeAll()
self.Choices,self.Keys = self.Form.courseChoices()
self.super()
"self.Form.courseChoices" is a method that retrieves the data.
And this is how I create the control on the form.
courselist=CourseDropDown(self, Width = 500, ValueMode = 'key', RegID =
'courseID', DataSource = "public.esenroll", DataField = "fk_escourse")
I don't recall how to add a new class to ClassDesigner and how to use it. But
I think Ed provided a way to get this done.
As always maybe this is not the best way and anyone can correct me.
