How many columns do you have in the table? If it isn't four, and they aren't in the right order, you will get an error, even if the "extra" columns are marked as "nulls allowed". Try reworking the insert statement to list teh fields in teh order they will be set:

SQL

INSERT INTO customers (name, address, insurance_cost, record_date) VALUES (@name,@address,@insurance_cost,@record_date)

BTW: You shouldn't use the Add method - it was depreciated years ago, and may not be supported in future versions. Use AddWithValue instead:

SQL

da.InsertCommand = new SqlCommand("INSERT INTO customers (name, address, insurance_cost, record_date) VALUES (@name,@address,@insurance_cost,@record_date)", con);
da.InsertCommand.Parameters.AddWithValue("@name", textBox1.Text);
da.InsertCommand.Parameters.AddWithValue("@address", textBox2.Text);
da.InsertCommand.Parameters.AddWithValue("@insurance_cost", textBox3.Text);
da.InsertCommand.Parameters.AddWithValue("@record_date", dateTimePicker1.Value);

Please recheck your query it's sytax is wrong.The correct Syntax is as follows :

da.InsertCommand = new SqlCommand("INSERT INTO customers (name,address,insurance_cost,record_date) VALUES (@name,@address,@insurance_cost,@record_date)", con);
            da.InsertCommand.Parameters.Add("@name", SqlDbType.NVarChar).Value = textBox1.Text;
            da.InsertCommand.Parameters.Add("@address", SqlDbType.NVarChar).Value = textBox2.Text;
            da.InsertCommand.Parameters.Add("@insurance_cost", SqlDbType.Money).Value = textBox3.Text;
            da.InsertCommand.Parameters.Add("@record_date", SqlDbType.DateTime).Value = dateTimePicker1.Value;
            con.Open();
            da.InsertCommand.ExecuteNonQuery();
            con.Close();

Also checkout the no of columns present in your table and no of columns you wrote in the query and their Names are proper or not. :)
