Question

I don’t know if it is called an argument (i.e. textbox1.text = "Hello";).

I have a control and there is a text box in it. It has a dropdown box that opens when the text is changed. But when I update the text in the text box that box drops down.

I need a way to make it so it only drops down if someone manually does it.

TBAddressBar.ABText.Text = getCurrentBrowser().Source.ToString();

and

    public void ABText_TextChanged(object sender, TextChangedEventArgs e)
    {
        if (sender == 1*)
        {
            ABDropDown.Visibility = Visibility.Visible;
        }
        else
        {
            ABDropDown.Visibility = Visibility.Collapsed;
        }
    }

Answer 1

If someone manually does it, presumably they are using keypresses to do so. In that case, use KeyDown or KeyUp events to show the dropdown instead.
