Question

I have a custom UserControl that contains just one TextBox.

When I set the control to Enabled = False, the TextBox is disabled but the control is not (control still fires the Enter event).

How do I ensure that the UserControl will not receive focus?

My Enabled Property Looks like this:

Private _Enabled As Boolean = True

Public Shadows Property Enabled As Boolean
    Get
        Return _Enabled
    End Get
    Set(value As Boolean)
        _Enabled = value
        txtTime.Enabled = value
    End Set
End Property

To answer your immediate question, you need to pass the enabled property to the base object:

public new bool Enabled {
    get { return _Enabled; }
    set {
        _Enabled = value;
        textBox1.Enabled = value;
        base.Enabled = value;
    }
}

However… the correct way to do it is using the OnEnabledChanged override:

protected override void OnEnabledChanged(EventArgs e) {
    textBox1.Enabled = this.Enabled;
    base.OnEnabledChanged(e);
}

(As you tagged it C#, I assume you can convert back to VB.net yourself)
