    <p>I'm working on an application with Razor mvc4 utulizando and when I try to display a list in a modal with a partial view gives runtime error telling me that the list that happened in the controller is null. I do not understand because it gives that error if I have a <strong>view</strong> that is similar to the <strong>partial view</strong> and passed the same list of parameters and if I sample. Please help me with this, because in issues I clarify my doubt.</p> <p>It is my view: </p> <pre><code>@model IEnumerable&lt;Activos_Fijos.Models.ActivoFijo&gt;&lt;table&gt;&lt;tr&gt;&lt;th&gt;@Html.DisplayNameFor(model =&gt; model.codigo)&lt;/th&gt;&lt;th&gt;@Html.DisplayNameFor(model =&gt; model.costo)&lt;/th&gt;&lt;th&gt;@Html.DisplayNameFor(model =&gt; model.descripcion)&lt;/th&gt;&lt;th&gt;@Html.DisplayNameFor(model =&gt; model.nombre)&lt;/th&gt;&lt;th&gt;@Html.DisplayNameFor(model =&gt; model.fecha)&lt;/th&gt;&lt;th&gt;@Html.DisplayNameFor(model =&gt; model.numserie)&lt;/th&gt;&lt;th&gt;@Html.DisplayNameFor(model =&gt; model.modelo)&lt;/th&gt;&lt;th&gt;@Html.DisplayNameFor(model =&gt; model.valorresidual)&lt;/th&gt;&lt;th&gt;@Html.DisplayNameFor(model =&gt; model.depreciacion)&lt;/th&gt;&lt;th&gt;@Html.DisplayNameFor(model =&gt; model.arearesponsabilidad)&lt;/th&gt;&lt;th&gt;@Html.DisplayNameFor(model =&gt; model.tipo)&lt;/th&gt;&lt;th&gt;@Html.DisplayNameFor(model =&gt; model.estado)&lt;/th&gt;&lt;th&gt;Detalles&lt;/th&gt;&lt;/tr&gt;@foreach (var item in Model) {&lt;tr&gt;&lt;td&gt;@Html.DisplayFor(modelItem =&gt; item.codigo)&lt;/td&gt;&lt;td&gt;@Html.DisplayFor(modelItem =&gt; item.costo)&lt;/td&gt;&lt;td&gt;@Html.DisplayFor(modelItem =&gt; item.descripcion)&lt;/td&gt;&lt;td&gt;@Html.DisplayFor(modelItem =&gt; item.nombre)&lt;/td&gt;&lt;td&gt;@Html.DisplayFor(modelItem =&gt; item.fecha)&lt;/td&gt;&lt;td&gt;@Html.DisplayFor(modelItem =&gt; item.numserie)&lt;/td&gt;&lt;td&gt;@Html.DisplayFor(modelItem =&gt; item.modelo)&lt;/td&gt;&lt;td&gt;@Html.DisplayFor(modelItem =&gt; item.valorresidual)&lt;/td&gt;&lt;td&gt;@Html.DisplayFor(modelItem =&gt; item.depreciacion)&lt;/td&gt;&lt;td&gt;@Html.DisplayFor(modelItem =&gt; item.arearesponsabilidad)&lt;/td&gt;&lt;td&gt;@Html.DisplayFor(modelItem =&gt; item.tipo)&lt;/td&gt;&lt;td&gt;@Html.DisplayFor(modelItem =&gt; item.estado)&lt;/td&gt;&lt;td&gt;@Html.ActionLink("Details", "Details", new { id=item.codigo }) &lt;/td&gt;&lt;/tr&gt;}&lt;/table&gt; </code></pre> <p>And it is my controller:</p> <pre><code> public ActionResult AFxResponsable() { PostgreNet bd = new PostgreNet(); DataTable tabla; List&lt;ActivoFijo&gt; lis = new List&lt;ActivoFijo&gt;(); bd.EstablecerConexion(); tabla = bd.DevolverTablaCompleta("empleado", " e inner join area_responsabilidad a on e.id_area=a.id inner join activo_fijo af on a.id=af.id_area group by e.id, a.id, af.codigo"); bd.CerrarConexion(); int i = 0; while (tabla.Rows.Count &gt; i) { lis.Add(new ActivoFijo { nombre = tabla.Rows[i]["nombre"].ToString(), arearesponsabilidad = int.Parse(tabla.Rows[i]["id_area"].ToString()), codigo = int.Parse(tabla.Rows[i]["codigo"].ToString()), costo = double.Parse(tabla.Rows[i]["costo"].ToString()), depreciacion = double.Parse(tabla.Rows[i]["depreciacion"].ToString()), descripcion = tabla.Rows[i]["descripcion"].ToString(), estado = int.Parse(tabla.Rows[i]["id_estado"].ToString()), fecha = tabla.Rows[i]["fecha"].ToString(), numserie = int.Parse(tabla.Rows[i]["num_serie"].ToString()), valorresidual = int.Parse(tabla.Rows[i]["valor_residual"].ToString()), modelo = tabla.Rows[i]["modelo"].ToString(), tipo = tabla.Rows[i]["id_tipo_medio"].ToString() }); i++; } return PartialView(lis); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
