You are developing an ASP.NET Web page that contains input controls, validation controls, and a
button named btnSubmit. The page has the following code-behind. (Line numbers are included for
reference only.)
01 public partial class _Default : System.Web.UI.Page
02 {
03 protected void SaveToDatabase()
04 {
05
06 }
07
08 protected void btnSubmit_Click(object sender,
EventArgs e)
09 {
10
11 }
12 }

database. What should you do?
