iam trying to write my own toolbox.At the moment i am trying to add a selection between Linear Unit and Field. I already got it working with a connection of String and Boolean as Data Type, but now i want to write it like this example ( Picture from Buffer Tool) :

In Delphi these "points" were called radio buttons but i dont know how to add them in ArcGis 10. Which Data Typ have i to choose for this relation ( field or linear unit)? Do i need any Validation Code?

Any solution?

Thanks for any help

Best Regards
