.Net 2.0 Web UserControl EditorAttribute Problem

[HawkEye]

Hi.

I'm trying to expose the DropDownList ListItemCollection property at design
time on a Web user control, using the following code.


<Category("Apearance"), Browsable(True), _

EditorAttribute(GetType(System.Web.UI.Design.WebControls.ListItemsCollectionEditor), _
GetType(UITypeEditor))> _
Public ReadOnly Property ListItems() As ListItemCollection
Get
Return Me.ddlControl1.Items
End Get
End Property

The problem is that the ListItems property is being displayed in
properties; but the editor button is not displaying. As far as i can see this
is virtualy identical to the example on MSDN.

i'm using the following assemblies -

Imports System.ComponentModel
Imports System.ComponentModel.Design
Imports System.Drawing.Design
Imports System.Web.UI.Design.WebControls

Please can anybody help.

Thanks
Ben
