I would like to create 2 combo boxes in an excel sheet - the data in whichnwill have a parent-child relationship. The second one will be populated dynamically depending on the option selected in the first combo. I am screwed up how to create Combo in Excel programitically and then how to manipulate it withing excel itself. Please remember that it will not have any Database connectivity. At most the data can be written in a sequential manner in a Sheet for reading.
