enum property displays as textbox not dropdown

Oct 28, 2011 at 6:04 PM
1. I created ascx
2. I added enum property
3. In Visual Studio, ascx properties pane displays a dropdown
4. I added to sharepoint via smart part
5. In Smart part property window, it is just a textbox (not dropdown)

what am I doing wrong? Thanks.
private myEnum _myEnum;

[Description("Select a value from the dropdown list.")]
public myEnum MyEnumProperty
return _myEnum;
_myEnum = value;
