Renderpartial or renderaction

Question

have an action that generates active vacancies. The code is below;

public ViewResult OpenVacancies() { var openvacancies = db.GetActiveVacancies(); return View(openvacancies); }

I want to use this list on several pages so i guess the best thing to use is html.renderaction (please correct me if i am wrong here).

Please note that the view and .ascx control are in an Area.

I then created a view by right clicking inside the action and create a .ascx and a strongly typed view of Vacancy. I chose a view content of "List".

I then added this line to the required page;

<% Html.RenderAction("OpenVacancies"); %>

Please note that the view and .ascx control are in an Area.

The error i got is;

The type or namespace name 'Vacancy' could not be found (are you missing a using directive or an assembly reference?)

the .ascx code is below;

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl>" %>

<table>
    <tr>
        <th></th>
        <th>
            VacancyID

Answer 1

First, if you simply want to reuse your view on multiple pages, you should be using a shared partial view (place it in the Shared folder) with <% Html.RenderPartial("OpenVacancies"); %>.

Second, based on your code snippet, your partial view doesn't appear to be strongly typed. Instead of

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>

you will want something like this:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<Vacancy>>" %>
