Identifier on grid lines

They could tell me if there is any simple property or way to put an identifier in the grid lines but without being the ID in the table, for example I have 5 records with id 32,45,99,100e and 200. But I want to put on grid 1,2,3,4 and 5. Like an auto increment, some suggestion ?

Code used for Grid:

    var lista = from substituidos in vagaDTO.Substituidos
                        where substituidos.Operacao != SysDTO.Operacoes.Exclusao
                        select new
                        {            

                            substituidos.IdClasse,
                            substituidos.Id,
                            Matrícula = substituidos.Matricula_Substituido ,
                            Substituído = substituidos.Substituido,
                            Contratante = substituidos.Numero_CTT,
                            Local = (substituidos.Endereco == null ? "" : substituidos.Endereco.Sigla),
                            Dt_Enc = string.Format("{0:dd/MM/yy}", substituidos.Data_Enc),
                            Dt_Saída = string.Format("{0:dd/MM/yy}", substituidos.Data_Saida),
                            Prev_Deslig = string.Format("{0:dd/MM/yy}", substituidos.Prev_Desligamento),
                            Prev_Fer_Ini = string.Format("{0:dd/MM/yy}", substituidos.Prev_Ferias_Inicio),
                            Prev_Fer_Fim = string.Format("{0:dd/MM/yy}", substituidos.Prev_Ferias_Final),
                            Fer_Ini = string.Format("{0:dd/MM/yy}", substituidos.Ferias_Inicio),
                            Fer_Fim = string.Format("{0:dd/MM/yy}", substituidos.Ferias_Final)

                        };

            //dtgSubstituidos.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill;
            lista = lista.OrderBy(p => p.Substituído).ToList();
            dtgSubstituidos.DataSource = lista.ToList();



            dtgSubstituidos.Columns[0].Visible = false;
            dtgSubstituidos.Columns[1].Visible = false;
            dtgSubstituidos.Columns[4].Visible = false;

            dtgSubstituidos.Columns[2].Width = 50;
            dtgSubstituidos.Columns[2].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight;

            dtgSubstituidos.Columns[3].Width = 150;
            dtgSubstituidos.Columns[5].Width = 200;

            dtgSubstituidos.Columns[6].Width = 60;
            dtgSubstituidos.Columns[6].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;

            dtgSubstituidos.Columns[7].Width = 60;
            dtgSubstituidos.Columns[7].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;

            dtgSubstituidos.Columns[8].Width = 60;
            dtgSubstituidos.Columns[8].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;

            dtgSubstituidos.Columns[9].Width = 60;
            dtgSubstituidos.Columns[9].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;

            dtgSubstituidos.Columns[10].Width = 60;
            dtgSubstituidos.Columns[10].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;

            dtgSubstituidos.Columns[11].Width = 60;
            dtgSubstituidos.Columns[11].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;

            dtgSubstituidos.Columns[12].Width = 60;
            dtgSubstituidos.Columns[12].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;

  • If you want to know which line you selected, just use grid.CurrentRow, so you don’t even need an identifier

declares a int outside the expression, and place a property with the value within the expression, and increase:

 int i  = 0;
 var lista = from substituidos in vagaDTO.Substituidos
                    where substituidos.Operacao != SysDTO.Operacoes.Exclusao
                    select new
                    {            
                        Sequencia = i++;
                        substituidos.IdClasse,
                        substituidos.Id,
                        Matrícula = substituidos.Matricula_Substituido ,
                        Substituído = substituidos.Substituido,
                        Contratante = substituidos.Numero_CTT,
                        Local = (substituidos.Endereco == null ? "" : substituidos.Endereco.Sigla),
                        Dt_Enc = string.Format("{0:dd/MM/yy}", substituidos.Data_Enc),
                        Dt_Saída = string.Format("{0:dd/MM/yy}", substituidos.Data_Saida),
                        Prev_Deslig = string.Format("{0:dd/MM/yy}", substituidos.Prev_Desligamento),
                        Prev_Fer_Ini = string.Format("{0:dd/MM/yy}", substituidos.Prev_Ferias_Inicio),
                        Prev_Fer_Fim = string.Format("{0:dd/MM/yy}", substituidos.Prev_Ferias_Final),
                        Fer_Ini = string.Format("{0:dd/MM/yy}", substituidos.Ferias_Inicio),
                        Fer_Fim = string.Format("{0:dd/MM/yy}", substituidos.Ferias_Final)

                    };

with this, your Grid column 0 will be the Sequencia.

Attention: your ordering should be done also in LINQ, otherwise nothing will help the numbering.
