我正在使用ASP MVC,我使用iTextSharp在我的应用程序中生成PDF.但现在我有一个问题:我打印列表,当存在多个页面时,我想显示页码(例如:)Page 1 to 4.我找到了一些例子,但我认为它比我需要做的更复杂(如exameple).

编辑: 我发现这个例子2.我可以计算页数,但我不能打印页数.

我做了什么:

public ActionResult downloadListaISCC(DateTime? DataFimFiltro)
{

//Code to generate list to PDF

   //My document
   Document doc1 = new Document();
   doc1.SetPageSize(iTextSharp.text.PageSize.A4);
   doc1.SetMargins(0f, 0f, 0f, 0f);
   doc1.NewPage();

   MemoryStream pdfStream = new MemoryStream();
   PdfWriter pdfWriter = PdfWriter.GetInstance(doc1, pdfStream);

   //Code to create table
   doc1.Add(table); //table list in document

   //Follow the example 2 (link)
   pdfWriter.CloseStream = true;
   doc1.Close();


   //E fui seguindo o exemplo do segundo link
   string file = "D:/gerarPDFOleotorres/"+ nomeDoc +""; …

我尝试更改默认的消息@Html.ValidationMessageFor.我可以在哪里查找邮件的文件:The _nameFied field is required.

视图:

@Html.ValidationMessageFor(model => model.NumDoc,"", new { @class = "error-input"})

我尝试删除控制器中的文件:

控制器:

[AcceptVerbs(HttpVerbs.Get)]
public JsonResult EliminarDocFotoContrato(int? DocFotoID)
{    
DocumentosFotosContrato docFoto = db.DocumentosFotosContrato.Find(DocFotoID);
var nomeDocFoto = docFoto.CaminhoDocFoto;
var dir = Server.MapPath("/uploads");
var path = Path.Combine(dir, nomeDocFoto);
var result = "Documento / Foto apagada.";
return Json(result, JsonRequestBehavior.AllowGet);
}

var nameDocFoto具有名称文件var dir具有目录并且路径具有nameDocFoto + dir(它是正确的)

现在我需要代码来删除文件.我可以帮帮我吗？我只是尝试这样的事情:

File.Delete(path);

但得到这个错误:

Error   2   'System.Web.Mvc.Controller.File(string, string, string)' is a 'method', which is not valid in the given context D:\VS2010\Projects\MvcTesteLayout\MvcTesteLayout\Controllers\_DadosComerciais\ContratoController.cs 1511    17  MvcTesteLayout

我尝试将输入键按下转换为选项卡而不提交表单,但只需删除提交表单按Enter键即可...

风景:

 <tr>
    <td><input type="text" id="tipoContacto1" name="tipoContacto1" class="form-control input-sm" onkeypress="removerEnter(event)"/></td>
    <td><input type="text" id="nomeContacto1" name="nomeContacto1" class="form-control input-sm" onkeypress="removerEnter(event)"/></td>

剧本:

function removerEnter(e) {
    if (e.which == 13) {
        //$(e).target.nextSibling;
        //$(this).next('input').focus();

        e.preventDefault();
    }
}

我尝试将razor值发送给jquery funcion.

视图:

@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 + ")" })

我可以使用除以外的所有参数 " + @Model.ServicosID + "

Js文件:

function PreencheDadosVendedor(idVend, tipoFuncionario, idServicoEdicao) {
$.getJSON("/Contrato/getDadosVendedor", { id: $(idVend).val(), 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);
      }
  });
}

我尝试做的idSericoEdicao是我的 …

我正在使用iTextSharp我的应用程序创建PDF.但是我必须重新创建一个表,我必须为一个非常小的列设置大小.下面是显示我想要设置列的大小的图片:

当表创建的其余部分都很好时,我无法设置此宽度.

码:

PdfPTable table = new PdfPTable(2);
table.WidthPercentage = 82.0f;
PdfPCell cell = new PdfPCell(new Phrase("Com a assinatura autógrafa, o signatário desta Auto-declaração garante ter cumprido estas condições:", fontetexto));
cell.PaddingBottom = 10f;
cell.PaddingTop = 10f;
cell.Colspan = 2;
cell.HorizontalAlignment = 1; //0=Left, 1=Centre, 2=Right
table.AddCell(cell);
table.AddCell("1. ");
table.AddCell("Os óleos e gorduras vegetais velhos fornecidos são biomassa conforme o Decreto de biomassa.");
