Hi all,

I am working on an MVC website, and am having a problem with passing data to my controller. My view has two partial views, and the one that is giving me a headache is below:

CableSummaryPartialView:

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

    <p>
        <%= Html.ActionLink("Create New", "Create") %>
    </p>
    <table>
        <tr>
            <th></th>
            <th>
                Id
            </th>
            <th>
                CableId
            </th>
            <th>
                System
            </th>
        </tr>

    <% foreach (var item in ViewData["cablesummary"] as IEnumerable<MagnoliaWeb.DAO.CableSummary>) { %>
    
        <tr>
            <td>
                <%= Html.ActionLink("Details", "Details", new { item.Id })%>
            </td>
            <td>
                <%= Html.Encode(item.Id) %>
            </td>
            <td>
                <%= Html.Encode(item.CableId) %>
            </td>
            <td>
                <%= Html.Encode(item.System) %>
            </td>
        </tr>
    
    <% } %>

    </table>

My ActionResult in my controller looks like this:

public ActionResult Details(int cableId)
        {
            ViewData["cablesummary"] = repository.GetCableListSummary();

            ViewData["cabledetails"] = repository.GetCableDetails(cableId);
            ViewData["cableterminations"] = repository.GetCableTermination(cableId);
            ViewData["cableroute"] = repository.GetCableRoutes(cableId);
            
            return View("Index");
        }

The problem appears to be that my View is passing my controller a null value. I have tried the code shown here, as well as trying to pass item as a whole and receiving it with a variable of the appropriate class.

Just so everyone knows, I have watched the value while debugging, and it is indeed passing a null...

Any ideas?

Thanks!

Ed

"passing a null" as in here Details(int cableId or here ViewData["cablesummary"] = repository.GetCableListSummary();
or here (var item in ViewData["cablesummary"] as IEnumerable<MagnoliaWeb.DAO.CableSummary>)?

Also,

What causes your partial view to display? is it the "Details" or the "Index" action? if it isn't "Details" can you post the Action?

I'd say problem is here:

<%= Html.ActionLink("Details", "Details", new { item.Id })%>

update it to:

<%= Html.ActionLink("Details", "Details", new { cableId = item.Id })%>

Hope this helps.
