Login cannot redirect to another page

I recently tried to use authentication and authorization on my login, but when I click to login nothing happens; it does not redirect

here is my code

Login.aspx.cs

 private bool ValidateUser(string email, string pass)
        {
            SqlConnection conn;
            SqlCommand cmd;
            string lookupPassword = null;

            // Check for invalid userName.
            // userName must not be null and must be between 1 and 15 characters.
            if ((null == email) || (0 == email.Length) || (email.Length > 15))
            {
                System.Diagnostics.Trace.WriteLine("[ValidateUser] Input validation of userName failed.");
                return false;
            }

            // Check for invalid passWord.
            // passWord must not be null and must be between 1 and 25 characters.
            if ((null == pass) || (0 == pass.Length) || (pass.Length > 25))
            {
                System.Diagnostics.Trace.WriteLine("[ValidateUser] Input validation of passWord failed.");
                return false;
            }

            try
            {
                // Consult with your SQL Server administrator for an appropriate connection
                // string to use to connect to your local SQL Server.
                conn = new SqlConnection("Data Source=(LocalDB)
                conn.Open();

                // Create SqlCommand to select pwd field from users table given supplied userName.
                cmd = new SqlCommand("Select pass from Users where email=@email", conn);
                cmd.Parameters.Add("@email", SqlDbType.NVarChar, 25);
                cmd.Parameters["@email"].Value = email;

                // Execute command and fetch pwd field into lookupPassword string.
                lookupPassword = (string)cmd.ExecuteScalar();

                // Cleanup command and connection objects.
                cmd.Dispose();
                conn.Dispose();
            }
            catch (Exception ex)
            {
                // Add error handling here for debugging.
                // This error message should not be sent back to the caller.
                System.Diagnostics.Trace.WriteLine("[ValidateUser] Exception " + ex.Message);
            }

            // If no password found, return false.
            if (null == lookupPassword)
            {
                // You could write failed login attempts here to event log for additional security.
                return false;
            }

            // Compare lookupPassword and input passWord, using a case-sensitive comparison.
            return (0 == string.Compare(lookupPassword, pass, false));
        }

        private void CmdLogin_ServerClick(object sender, System.EventArgs e)
        {
            if (ValidateUser(txtUserName.Value, (txtUserPass.Value)))
                FormsAuthentication.RedirectFromLoginPage(txtUserName.Value, chkPersistCookie.Checked);
            else
                Response.Redirect("Login.aspx", true);
        }
