    <p>I'm very new to MVC and have run into this issue while trying to port an existing site to MVC4. </p> <p>We're using models where much of the data is populated by service calls, so obviously we'd like to keep the calls to a minimum. The problem is that when I try to pass the model back to the controller, the complex objects within the model invariably become null. I have been able to persist the data on a call back to the controller using ajax; however, I need the action to return a new view, and after the action completes, the code for the view executes, but there is no redirect (which I believe is the point of ajax, I think what I'm asking for is a solution that will persist the data in the same way but actually redirect).</p> <p>Here is my model:</p> <pre><code>public class DistributionModel { public string typeOfDistribution { get; set; } public Document document { get; set; } public string thumbnailUrl { get; set; } public MergeFieldModel mergeFields { get; set; } } public class MergeFieldModel { public MergeFields documentMergeFields { get; set; } } </code></pre> <p>Here is the controller action I am using:</p> <pre><code> public ActionResult Index(DistributionModel distributionModel) { distributionModel.mergeFields = new MergeFieldModel() { documentMergeFields = MergeFieldsHelper.GetDocumentMergeFields(distributionModel.document.Id) }; return View("Index", distributionModel); } </code></pre> <p>I tried using a href=@Url.Action("Index", Model) instead of the button in the block below to call the controller and perform the redirect (the redirect itself did work, but I then had to perform another service call within the controller to retrieve the same document as I was working with from the calling view) because the Document object within the model kept returning as NULL to the controller.</p> <p>Here is the portion of the view that is calling the controller and actually returns the complete model: I think what I am looking for is a way to accomplish this without ajax so that I can get the redirect to the Distribution/Index page (this is fired from Distribution/DocumentDetails page) </p> <pre><code> &lt;button id="EmailDistribution" data-corners="false" data-theme="a"&gt;EMAIL&lt;/button&gt; $('#EmailDistribution').click(function () { var model = @Html.Raw(Json.Encode(Model)); $.ajax({ url: '@Url.Action("Index", "Distribution")', type: 'POST', contentType: 'application/json; charset=utf-8', data: JSON.stringify(model), processData: false, }); }); </code></pre> <p>Thanks, any help would be very much appreciated.</p>

    1. COWhy can you just have `return RedirectToAction("Index", distributionModel);` as last line of `Distribution/DocumentDetails` action?

    2. COThe DocumentDetails action returns the DocumentDetails view. Additionally, I tried doing a RedirectToAction from one of the controller methods, and found it passed the Document object to the other action as NULL.

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.

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