After adding a custom property to a UserControl how can this property value be changed in the property sheet when in WinForm design mode? The property shows up disabled in the property sheet.

Code which defines the property in the UserControl

Private mcText As String = "Place Filter Here"

    Public Property cText() As String
        Get
            Return mcText
        End Get
        Set(ByVal Value)
            mcText = Value
            FilterYes.Text = Value
        End Set
    End Property

Thanks
