wish of those help If your creating a registration it would be like this. Change the names for these the way they are called in your database and for the other ones to. (@FirstName, @Surname, @Password, @Username,)
code :
   protected void Button1_Click(object sender, EventArgs e)
        {
            try
            {

                SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["YOUR_CONNECION_STRING_HERE"].ConnectionString);

                conn.Open();


                string insertQuery = "insert into Table1(FirstName, Surname, Username, Password) " +
                    "values(@FirstName, @Surname, @Password, @Username,)";
                SqlCommand com = new SqlCommand(insertQuery, conn);


                com.Parameters.AddWithValue("@FirstName", Textbox1.Text);
                com.Parameters.AddWithValue("@Surname", Textbox2.Text);
                com.Parameters.AddWithValue("@Password", Textbox3.Text);
                com.Parameters.AddWithValue("@Username", Textbox4.Text);

                //This actually executes the query with the given values above.
                com.ExecuteNonQuery();


                conn.Close();

                Response.Redirect("Name_Of_Any_Page_Thats_On_Your_Site.aspx");

                Response.Write("there was a problem with your registration");

            }
            catch (Exception problem)
            {
                //throw Exception ;
                Response.Write("Error Message: " + problem.ToString());
                throw;

            }

Form submit capture into database not working

I wish did fix the issue. It will fail to capture this button press if someone hits "enter" to submit the form. If this is a data item, it would be better to capture it in a different way to be honest, as this only works when someone clicks the button or focusses the button before hitting enter.
Hitting enter to submit a form is default behaviour for browsers, albeit with a few variations based on form size and field type (for example, a textarea will not submit on enter, but an input type="text" will submit on enter).

I wish did fix the issue. Change the single quotes surrounding the table name and the column name to backticks. Or get rid of them all together.
code :
$sql="INSERT INTO `test` (`name`)  VALUES ('{$_POST['namefield']}')";

will help you You need to add method="post" to your form..!
The reason all your conditions are failing is because $_POST is null. You aren't posting any data since the default form method is GET.

around this issue You have a DB class which is good to separate you database code from your user interface code. I moved the database code to retrieve the Country data to the DB class. Notice how the DB class knows nothing about the user interface and the user interface knows nothing about the database.
Database objects need to be closed and disposed. using blocks take care of this for you even if there is an error.
code :
    public class DB
    {
        private string ConStr = "Your connection string";

        public DataTable GetCountryData(string nC)
        {
            DataTable dt = new DataTable();
            using (SqlConnection cn = new SqlConnection(ConStr))
            using (SqlCommand cmd = new SqlCommand("SELECT * FROM Voucher WHERE Name_Country= @nC", cn))
            {
                cmd.Parameters.Add("@nC", SqlDbType.VarChar, 100).Value = nC;
                cn.Open();
                dt.Load(cmd.ExecuteReader());
            }
            return dt;
        }
    }
    private void OpCode()
    {
         if (comboBox1.SelectedIndex < 0)
         {
            MessageBox.Show("Please select a value in the drop down.");
            return;
         }
        DB DataClass = new DB();
        dataGridView1.DataSource = DataClass.GetCountryData(comboBox1.SelectedValue.ToString());
    }
