Sometimes it's convenient to have a property that limits the user to selecting from a fixed set of choices. For instance, in the SortedList.cst template, the Accessibility property controls the accessibility of the generated class:
To accomplish this, you need to take two steps. First, define an enumeration in a <script> block in your code:
<script runat="template">
Public Enum AccessibilityEnum
[Public]
[Protected]
[Friend]
[ProtectedFriend]
[Private]
End Enum
</script>
Second, the Property directive should point to the enumeration:
<%@ Property Name="Accessibility" Type="AccessibilityEnum" Category="Options" Description="The accessibility of the class to be generated." %>
That's all there is to it!
