After tryingseveral optionsI fail todeploya report andI am not gettinganyspecific error.


I am developingin VisualStudio 2010withMVC3Razor.


I havea viewto invoice

This is part of the view:

@model Models.FacturaHeaderModel
@{    ViewBag.Title = "Facturación de Compras";    Layout = "~/Views/Shared/_Layout.cshtml";    }
@using (Html.BeginForm("Guardar", "Facturas", FormMethod.Post, new { id = "factura" }))
{    <fieldset>        <div class="editor-label" style="font-size:16px;">            @Html.LabelFor(m => m.Movimiento.DescripLarga)            <div class="editor-field">                @Html.TextBoxFor(m => m.Movimiento.DescripLarga, new { @readonly = "readonly", style = "font-weight: bold;font-size:16px;" })            </div>        </div>
....    </fieldset>        <input type="submit" name="Guardar" id="guardar" title="Guardar" value="Guardar" />
}

 

This is part of ActionResult

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Guardar(FacturaHeaderModel model, FormCollection formCollection)
{            if (ModelState.IsValid)            {
..... save data.......                var reporte = System.Web.HttpContext.Current.Request.PhysicalApplicationPath + @"rpt\Factura.rpt";                var rptH = new ReportClass { FileName = reporte };                rptH.Load();                var cnn = new ReportHelper();                cnn.Connect(ref rptH); //connect database                rptH.RecordSelectionFormula = "{CtaCteCliente.CtaCteClienteId}=" + facturaId;                var stream = rptH.ExportToStream(ExportFormatType.PortableDocFormat);                return File(stream, "application/pdf");            }
}

 

For some reasonthough thereport is designedproperly andfrom the designerworking properlyand after makingseveral attempts todebug thecode to detectthat is wrongdoes not seem tobeanything unusual.

Some queries:
This error maybe caused bythe type of responseexpected byvisual studio?

Is there anyway to getcrystal reportserrorin previousversionsassomething like:

rptH.LastError
