Problem with Browsable(True) in web user control property

[Alli]

I have a web user control with a property that has the browsable
attribute set to true, but property doesn't show up in the HTML design
property window when I add the control to a web form.

My property is:

Imports System.ComponentModel
....

<DesignerSerializationVisibility(DesignerSerializa tionVisibility.Visible),
_
EditorBrowsable(EditorBrowsableState.Always), _
Browsable(True), _
Category("Behavior"), _
Description("Name of textbox to return the date value to")> _
Public Property ReturnDateToField() As String
Get
Return txtReturnDateToField.Text
End Get
Set(ByVal Value As String)
txtReturnDateToField.Text = Trim(Value)

InitDatePickerLink()
End Set
End Property
Everything builds and runs fine; it's just that I can't see the
ReturnDateToField property in the property window. Thanks for your
help!
