Hi,

I have a textbox which binds to some underlying data. I also have an autocomplete combobox which I want to use to allow better searching than a plain combo will. However, it cannot bind to the underlying data (or at least I haven't been able to make it). So what I am trying to do is only show the autocomplete combo when the user actually clicks or moves to the textbox. Initially I make the combo invisible, then in the gotfocus of the textbox I want to hide the textbox and show the combo. I've tried this code:

        private void txtCus_Number_GotFocus(object sender, RoutedEventArgs e)
        {
            this.txtCus_Number.Visibility = Visibility.Hidden;
            this.autoCustomers.Visibility = Visibility.Visible;
            this.autoCustomers.Focus();

        }

        private void autoCustomers_LostFocus(object sender, RoutedEventArgs e)
        {
            this.autoCustomers.Visibility = Visibility.Hidden;
            this.txtCus_Number.Visibility = Visibility.Visible;

        }

but the textbox never gets hidden. In VFP I might put a NODEFAULT in the gotfocus code. Is there something similar in C# or should I do this a different way?
