{
    this.contactsTableAdapter.Fill(this.contactsDataSet.Contacts);
    dataGridView1.DataSource = contactsDataSet.Contacts;
    try
    {
        DataRow row = contactsDataSet.Contacts.NewRow();
        row[0] = contactsDataSet.Contacts.Rows.Count + 1;
        row[1] = "Dsatasdasfo";
        row[2] = "Maisgfdgdfuradze";
        row[3] = 596110800;
        row[4] = "Tserefgdfgdteli Ave, Building 10";
        contactsDataSet.Contacts.Rows.Add(row);
    }
    catch (ConstraintException error)
    {
        MessageBox.Show(error.Message,"Error",MessageBoxButtons.OK,MessageBoxIcon.Warning);
    }
    finally
    {
        contactsTableAdapter.Adapter.Update(contactsDataSet.Contacts);
    }

您不需要将更改保留在代码中的数据库中，您需要调用：

ContactsDataAdapter.Update()
