Disable ComboDropDown
How do you disable a ComboDropDown. set "ENABLED" to 0 and it greyed, but the dropdown button can still be clicked.
Comments
Setting the ENABLED property of the edit line control only affects the edit line itself. The reason you might want this is if you wanted to create a simple combobox which only allowed the user to select from the dropdown list.
If you need to disable the dropdown itself then you also need to set the OptionEnabled property to false.
