Chekbox column in datagridview

Question

I’m getting an error after I put a chekbox column in the datagridview on my screen, and this screen is loaded by a query, put this chekbox column not in the query but directly in the datagridview.

follows the code

private void ListaGrid()
    {
        try
        {
            SqlCommand separacao = new SqlCommand("usp_SeparacaoPic", conexaoDADOADV(true));
            separacao.CommandType = CommandType.StoredProcedure;
            separacao.ExecuteNonQuery();

            SqlDataAdapter dados = new SqlDataAdapter(separacao);
            DataTable dtLista = new DataTable();
            dados.Fill(dtLista);

            dgw_separacaopic.DataSource = dtLista;

        }
        catch
        {
            MessageBox.Show("Não exstem dados digitados para a consulta, por favor verificar!!!");
            return;
        }
    }

Thanks in advance.
