How to save gridview data into database at a time

refer this http://stackoverflow.com/questions/10556556/insert-all-data-of-a-datagridview-to-database-at-once[^]

Are you using the entity framework? This is possible if you use an EntityDataSource instead of a SqlDataSource. When you get the data in the code behind, you can just attach it to an entity context.

foreach (DataGridViewRow row in dataGridView1.Rows)
{
if (row.Cells[0].Value == null && row.Cells[1].Value == null && row.Cells[2].Value == null && row.Cells[3].Value == null && row.Cells[4].Value == null && row.Cells[5].Value == null && row.Cells[6].Value == null && row.Cells[7].Value == null)
{

}
else
{
con.Open();
OleDbCommand cmd = new OleDbCommand("insert into Sold(Product_name,Model_no,Seater,Leather,Colour,Unit_price,Quantity,Total,Advancepayment,Duespayment) values (@Product_name,@Model_no,@Seater,@Leather,@Colour,@Unit_price,@Quantity,@Total,@Advancepayment,@Duespayment)", con);

cmd.Parameters.AddWithValue("@Product_name", row.Cells[0].Value.ToString());
cmd.Parameters.AddWithValue("@Model_no", row.Cells[1].Value.ToString());
cmd.Parameters.AddWithValue("@Seater", row.Cells[2].Value.ToString());
cmd.Parameters.AddWithValue("@Leather", row.Cells[3].Value.ToString());
cmd.Parameters.AddWithValue("@Colour", row.Cells[4].Value.ToString());
cmd.Parameters.AddWithValue("@unit_price", row.Cells[5].Value.ToString());
cmd.Parameters.AddWithValue("@Quantity", row.Cells[6].Value.ToString());
cmd.Parameters.AddWithValue("@Total", row.Cells[7].Value.ToString());
cmd.Parameters.AddWithValue("@Advancepayment", textBox4.Text);
cmd.Parameters.AddWithValue("@Duespayment", label35.Text);

cmd.ExecuteNonQuery();
}
}

i don't know dear without looping so....
