对RadioButtonList没有反应

Question

我想根据在RadioButtonList中检查radiobutton off来显示Textboxes，但是没有显示任何更改。

protected void Page_Load(object sender, EventArgs e)
{
}

protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
    switch (RadioButtonList1.SelectedIndex)
    {
        case 2:
            TextBox3.Visible = true;
            goto case 1;
        case 1:
            TextBox2.Visible = true;
            goto case 0;
        case 0:
            TextBox1.Visible = true;
            goto default;
        default:
            break;
    }
}
