Data is not being updated on SQL Server from Web Page

Question

I recently started on C#.Net. I am having some trouble with updating my sql server database. This page is just a basic "Create an account". The user submits username,password and email. The program takes it and puts it into a table with UserName, Password, and Email columns. The Problem is that its not writing to the database. I am VERY new to .net (transitioning from Java) and any input is greatly appreciated.

C# Code:

namespace WebApplication1.Account
{
    public partial class Register : System.Web.UI.Page
    {

        protected void Page_Load(object sender, EventArgs e)
        {
            RegisterUser.ContinueDestinationPageUrl = Request.QueryString["ReturnUrl"];


        }

        protected void Button_Click(object sender, EventArgs e)
        {
            Button btn = (Button)sender;

            if (btn.ID == "CreateUserButton")
            {

                String cmdText = "dbo.InsertUser";

                String connStr = ConfigurationManager.ConnectionStrings["PracticeConnectionString"].ConnectionString;
                SqlConnection conn = new SqlConnection(connStr);
                conn.Open();

                SqlCommand cmd = new SqlCommand(cmdText, conn);
                cmd.CommandType = CommandType.StoredProcedure;

                FormView fv1 = new FormView();
                fv1.DataBind();

                try
                {
                    String userName = null, password = null, email = null;

                    TextBox Username = (TextBox)fv1.FindControl("UserName");
                    userName = Username.Text.ToString();
                    TextBox Email = (TextBox)fv1.FindControl("Email");
                    email = Email.Text.ToString();
                    TextBox Password = (TextBox)fv1.FindControl("Password");
                    password = Password.Text.ToString();

                    SqlDataSource src = new SqlDataSource();
                    src.DataBind();
                    src.InsertParameters.Clear();
                    src.InsertParameters.Add("UserName", TypeCode.String, userName);
                    src.InsertParameters.Add("Password", TypeCode.String, password);
                    src.InsertParameters.Add("Email", TypeCode.String, email);
                    src.Insert();

                    cmd.ExecuteNonQuery();

                }
                catch (Exception exc)
                {
                    Console.WriteLine(exc.StackTrace.ToString());
                }
                finally
                {
                    if (conn != null && conn.State == ConnectionState.Open)
                    {
                        conn.Close();
                        conn = null;
                        cmd = null;
                    }
                }


                Response.Redirect("~/HomePage.aspx");
            }

        }

        protected void RegisterUser_CreatedUser(object sender, EventArgs e)
        {
            FormsAuthentication.SetAuthCookie(RegisterUser.UserName, false /* createPersistentCookie */);

            string continueUrl = RegisterUser.ContinueDestinationPageUrl;
            if (String.IsNullOrEmpty(continueUrl))
            {
                continueUrl = "~/";
            }
        }

        protected void OnInsert(object sender, EventArgs e)
        {

        }
        protected void onInserted(object sender, EventArgs e)
        {
            Response.BufferOutput = true;
            Response.Redirect("HomePage.aspx");
        }
    }

Answer 1

You will need to use SQL Profiler to view the SQL query being passed through to the sql server. If you can run that query in the Sql Server Management Studio (SMSS), or whatever tool, and the data updates then you will need to look for your error in the code.

If it does not update the table when run directly through SMSS then you will need to debug the query.
