The UserComboBox control allows the creation of a custom template to use as the dropdown portion of the ComboBox.

For a full list of properties, methods and events see the API documentation.


Custom Controls

The DropDownControl property of the UserComboBox control specifies which control to use as a template for the drop down panel of the combo box.
