Custom Data type not showing up

I have the following, issue, i created a new custom datatype with the Umbraco usercontrol wrapper.

I just based it on a few samples, and the code is compiling correctly.

Also when i create a new datatype, the usercontroll is showing up in the correct way.

Does anybody know or this might be a issue in V6?

I am running version 6.2.5

My code: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="CustomDropDown.ascx - Pastebin.com
