Custom Control

[Memnoch1207]

Okay, here is the dilemma.
I have created a custom control that consists of a textbox and an optional required field validator.
Everything works fine except for one minor problem.

I have overridden some of the properties, such as Font, BackColor, BorderStyle, etc.. and have made these properties invisible in the properties window, using <Browsable(False)> _.

The problem is, in the code-behind (using VS.NET) Intellisense still displays the hidden properties.
All the examples I have seen say to use the EditorBrowsable(EditorBrowsableState.Never) attribute to prevent Intellisense from displaying it, but this isn't working....

Here's a sample control I created to test this.

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


Public Class MyTextBox
    Inherits TextBox

    Private txtBox As TextBox

    Public Sub New()
        txtBox = New TextBox
    End Sub

    Protected Overrides Sub render(ByVal writer As HtmlTextWriter)
        MyBase.Render(writer)
    End Sub
 
    Browsable - prevents the property from being seen in the properties window...This works

    EditorBrowsable - prevents the property from being referenced in intellisense 
    in the code-behind...This doesn't work!

    Obsolete - Prevents a developer from using this property. 
    If the developer tries to use this property in the code-behind
    and compile it. The message is supposed to display in the 
    task list as an error.
    "This property isn't supported."...This doesn't work!  

    <Browsable(False), _
    EditorBrowsable(EditorBrowsableState.Never), _
    Obsolete("This property isn't supported.", True)> _
    Public Overrides Property BackColor() As Color
        Get
            Return Nothing
        End Get
        Set(ByVal Value As Color)
            txtBox.BackColor = Nothing
        End Set
    End Property

End Class

Any ideas why???
