Problem with IDE when overriding Text property

I noticed when overriding the Text property of the
System.Windows.Forms.UserControl that the Form.Designer file does not
reflect changes made via the property browser. In other words, when you
override the Text property and then try to change it's value at design-time,
the value is not serialized and therefore not available at run-time.

This problem does not appear to be language specific; I've reproduced it in
C# and in VB. Here are examples of what I've written:

In VB:
    <System.ComponentModel.Browsable(True)> _
    Public Overrides Property Text() As String
        Get
            Return lblTitle.Text
        End Get
        Set(ByVal value As String)
            lblTitle.Text = value
        End Set
    End Property

In C#:
        [System.ComponentModel.Browsable(true)]
        public override string Text
        {
            get { return lblTitle.Text; }
            set { lblTitle.Text = value; }
        }

Can anyone explain to me what is happening and how I might correct the
problem?

You'll need to add some more attributes. See the example at the link below.
