A "Value List", which contains a set of value/description pairs that will appear in a drop-down within the Excel Formula Wizard.
class CXlWizExUIListProvider |
An add-in can extend the Excel Formula Wizard user interface by displaying a drop-down button on an argument field. When the user clicks on the button (or presses the down arrow key), a drop-down list of values (each with a description) appears: this list is provided by a CXlWizExUIListProvider object.
The XLL+ Function Wizard generates all the code required for this functionality: just populate the Value List for an argument, and set the ShowValueListInFormulaWizard property to true.
