What nobody mentioned is you are constantly adding new parameters to the SqlCommand.Parameters, on every pass of the loop.

You're not reusing parameters, you're creating new ones on every iteration of the loop. On the first iteration of the loop, your Parameters collection will have 11 parameters. On the second, 22 parameters. On the 3rd, 33 parameters...

Create the parameters OUTSIDE the loop, then just set the values inside.
SqlCeConnection connection = new SqlCeConnection();
            connection.ConnectionString = @"Data Source=C:\Users\Dell\Desktop\DataGridView\PMinfo.sdf";

            SqlCeCommand myCommand = new SqlCeCommand(@"INSERT into [PMinfo] (Number, CostCenter, pType, ServiceType, Receiver, WorkCenter, Start, End, Remaining, Status, ReceiveDate) values(@Number, @CostCenter, @pType, @ServiceType, @Receiver, @WorkCenter, @Start, @End, @Remaining, @Status, @ReceiveDate)");

            myCommand.Connection = connection;

            //
            // You'll have to set the DB type of each parameter to what the database expects.
            //
            myCommand.Parameters.Add("@Number", SqlDbType.NVarChar);
            myCommand.Parameters.Add("@CostCenter", ...);
            myCommand.Parameters.Add("@pType", ...);
            myCommand.Parameters.Add("@ServiceType", ...);
            myCommand.Parameters.Add("@Receiver", ...);
            myCommand.Parameters.Add("@WorkCenter", ...);
            myCommand.Parameters.Add("@Start", ...);
            myCommand.Parameters.Add("@End", ...);
            myCommand.Parameters.Add("@Remaining", ...);
            myCommand.Parameters.Add("@Status", ...);
            myCommand.Parameters.Add("@ReceiveDate", ...);

            connection.Open();

            for (int i = 0; i < dataGridView1.Rows.Count; i++)
            {
                myCommand.Parameters["@Name"] = dataGridView1.Rows[i].Cells[0].Value.ToString();
                myCommand.Parameters["@CostCenter"] = ...
                ...

                myCommand.ExecuteNonQuery();
            }

            connection.Close();

DO NOT STORE DATES AS STRINGS IN THE DATABASE! Store them as the appropriate DateTime type.
