This ComboBox is derived from the Microsoft
ComboBox and has some extra features. Such as null support and parameterized
queries.
You do not need to code anything! Just fill in some properties.
Automatically the list is filled for you.
Example:
Just in time list loading
Simply set the "LoadListOn" property to load the list when the Form is loaded
or only when the Tabpage is selected (if your ComboBox is located on a
TabPage). In this last case the performance is increased at Form load time.
Null support
This ComboBox handles null values for you. A "(none)" entry is added to the
list. Of course this text can be changed by your own custom text. This
is a handy feature, because by default a normal ComboBox does not handle
this for you.
