Answer 1

This is happening because you are setting the label to "???!!" every page event.

You need to modify your page load to detect f a Postback has not occured.

    protected void Page_Load(object sender, EventArgs e) {
        if(!IsPostBack)
        {
            label1.Text = "???!!";
        }
    }
