Declaring an enumerated property

Sometimes you want a property that limits the user to a fixed set of choices. For example, the Accessibility property of the SortedList.cst sample template controls the accessibility of the generated class, and the property grid shows the choices in a drop-down list:

It takes two steps.

1. Define an enumeration in a <script runat="template"> block. In a Visual Basic template:

   <script runat="template">
   Public Enum AccessibilityEnum
         [Public]
         [Protected]
         [Friend]
         [ProtectedFriend]
         [Private]
   End Enum
   </script>
   

2. Use the enumeration as the type in the Property directive:

   <%@ Property Name="Accessibility" Type="AccessibilityEnum" Category="Options" Description="The accessibility of the class to be generated." %>
   

The property grid then offers each member of the enumeration as a choice, and the template code reads the selected value from the Accessibility property.
