Insert Record Into Sql Database Express When Button Pressed

I'm new to asp.net and I have gotten quite far with books and such but I'm stuck at this point. I have a web form that is mostly populated with data pulled from AD and all the user does is make a selection in two drop lists and enter their initials to sign. I can't figure out how to insert a record into a table when buttin pressed. I verified that all the data types are correct so it shoud pass the info but its just not going anywhere. I've atached the code below.

Thanks,protected void accept_btn_Click(object sender, EventArgs e)

{

string adPath = LDAP://DC=********,DC=***; //Path to your LDAP directory servermembers adAuth = new members(adPath);

 string username = Context.User.Identity.Name;

string computer_name = System.Environment.MachineName;string comp_type = comptype.SelectedValue.ToString();

string install_type = installtype.SelectedValue.ToString();string date = DateTime.Now.ToString();

string email = adAuth.getemail(Context.User.Identity.Name);string agree = initials_txtbox.Text;string title = "Office";

 test_lbl.Text = (username + " " + computer_name + " " + comp_type + " " + install_type + " " + date + " " + email + " " + agree + " " + title);
