Question : UI Type Editor in VS2010

I'm building a custom server control that has a "Text" property. I want to be able to edit that property in a large dialogue box as it often contains a lot of text.

I can't seem to get the right Editor settings What goes in the "?" spaces
********
<Bindable(True), Category("Appearance"), DefaultValue(""), Localizable(True), Editor(GetType(?), GetType(?))>
Property Text() As String
Get
Dim s As String = CStr(ViewState("Text"))
If s Is Nothing Then
Return "[" & Me.ID & "]"
Else
Return s
End If
End Get

Set(ByVal Value As String)
ViewState("Text") = Value
End Set
End Property

Thanks

Sorry, I don't know of an existing one, but if you use BigStringEditor and UITypeEditor for the "?"s, and define a class BigStringEditor as in the included code (sorry, I don't have VB.Net on my machine, but the code should be almost the same) then when you click in the property a "..." will appear (I think you need to set Browsable(true) also) and if you click on that a 100x100 dialog will appear which will let you edit.
