Answer 1

The reason you are getting undefined (Assuming value is a string) is because you need to wrap @Model.ServicosID it in quotes, otherwise it will look for the value of the property as the name of the variable, instead you just need to pass the value as the a string.

Try this:-

@Html.TextBoxFor(model => model.NumTransportado, 
                  new { @class = "form-control input-sm", 
                    id = "NumTransResp" + Model.ServicosID + "", 
                    name = "NumTransResp" + Model.ServicosID + "", 
                    onchange = "PreencheDadosVendedor(this, 3, '" + @Model.ServicosID + "')" });
                                                               ^____                     ^____                                  

Or better do this, instead of adding an onchange attribute; attach an event instead and make use of data-* attributes to store element specific values, this way you separate out html and js:

i.e:

@Html.TextBoxFor(model => model.NumTransportado, 
                      new { @class = "form-control input-sm myclass", //Add a class  
                        id = "NumTransResp" + Model.ServicosID + "",
                        data_tipoFuncionario = 3, //Add a data attribute 
                        name = "NumTransResp" + Model.ServicosID + ""});

and

$('.myclass').change(function(e){
     var idServicoEdicao = this.id.replace("NumTransResp",""),  //get the part from its own id
         tipoFuncionario = $(this).data("tipoFuncionario"); //get the value from data attribute

     $.getJSON("/Contrato/getDadosVendedor", { id: this.value, tipoFuncionario: tipoFuncionario },
 function (result) {
      switch (tipoFuncionario) {
          case 1:
              $("#NomeVendedor_Contrato").val(result.NomeVendedor);
          case 2:
              $("#NomeTransResponsavel").val(result.NomeVendedor);
          case 3:
              $("#NomeTransResponsavel_" + idServicoEdicao).val(result.NomeVendedor);
      }
  });

});
