Answer 1

If you don’t want to postback you will need to use javascript. For example if you use jQuery you could subscribe to the .change() event of the dropdown and set the value of the textbox:

$(function() {
    $('#id_of_your_drop_down').change(function() {
        var selectedValue = $(this).val();
        $('#id_of_your_text_box').val(selectedValue);
    });
});

I would also recommend you going through the getting started tutorials in the jQuery documentation as this is quite basic functionality.
