Hello all, I am a newbie in programming and I have come across a problem that searches on the web hasn't yet presented me with a solution. I am able to save a new record to a database but I will have to restart the application in order to view the new entry. Below is the code that I use to send the record to the database. Any help is highly appreciated.

DataSet ds = new DataSet();
SqlConnection con = new SqlConnection("Data Source=ACER-SVR;Initial Catalog=ISL;Integrated Security=True");

private void button1_Click(object sender, EventArgs e)
{
    string select = "Select * from isltb";
    SqlDataAdapter da = new SqlDataAdapter(select, con);
    SqlCommand insert = new SqlCommand("_insert", con);

    insert.CommandType=CommandType.StoredProcedure;             
    insert.Parameters.Add("@com", SqlDbType.NVarChar).Value = textBox1.Text;
    insert.Parameters.Add("conper", SqlDbType.Text).Value = textBox5.Text;
    insert.Parameters.Add("@desig", SqlDbType.Text).Value = textBox6.Text;
    insert.Parameters.Add("@tel", SqlDbType.Int).Value= int.Parse(textBox4.Text);
    insert.Parameters.Add("@mob", SqlDbType.Int).Value= int.Parse(textBox7.Text);
    insert.Parameters.Add("@addr", SqlDbType.NVarChar).Value= textBox8.Text;
    insert.Parameters.Add("@email", SqlDbType.NVarChar).Value = textBox9.Text;

    con.Open();           
    insert.ExecuteNonQuery();            
    MessageBox.Show("...SUCCESS...");
    da.Fill(ds, "isltb");            
    con.Close();
}
