Fill a combobox based on selection in other combobox
Hello,
I have a custom screen with 3 comboboxes.
The first one has data. (In my case world regions. - Asia, Europe, etc.)
The second and third one are empty.
When I select an item in the first combobox the second combobox has to be filled. (In my case countries in the selected region)
When I select an item in the second combobox the third combobox has to be filled. (In my case cities in the selected country from combobox 2)
How can I do this?
It seems that there are no 'events' that I can trap.
I know how to fill a combobox, but not how to detect a change in selection.:cry:
I am totally lost here.
Regards Johan
