    <p>Suppose I have a parent.cshtml view with a parentModel, and a child.cshtml view with a childModel. This child action is <code>[ChildActionOnly]</code> and is rendered in parent.cshtml: <code>@Html.Action("ChildAction")</code>.</p> <p>Now, in controller/ParentAction</p> <pre><code>public ActionResult ParentAction() {return View();} [HttpPost] public ActionResult ParentAction(ParentModel parentmodel) { if(!ModelState.IsValid) { ... ModelState.AddModelError("", "parent view has an error"); } return View(parentmodel); // pass the ball back to user } </code></pre> <p>in controller/ChildAction</p> <pre><code>[ChildActionOnly] public ActionResult ChildAction() {return View();} [HttpPost] public ActionResult ChildAction(ChildModel childmodel) { if(!ModelState.IsValid) { ... ModelState.AddModelError("", "child view has an error"); } //??? return ParentView(parentmodel, childmodel) ??? how do i do this??? } </code></pre> <p>In the child action, how do I return to the ParentView (that also renders the ChildView), and preserve the data in their models?</p> <p>EDIT:-----</p> <p>My point is how not to do that. <code>return View(childmodel);</code> from child action will not get us what we want to see, because it will only give us a 'partial' page with child view only, the parent part is missing. <code>RedirectToAction("ParentAction");</code> will give us full view again, but it will lose the models. Not sure how to handle returning models in nested views. That's where I am stuck. </p>

    1. COTry putting your childModel as a child of your parentModel. Pass childModel to a child controller and subsequently ignore it inside your parent controller.

    2. CO@Aleksey: child.cshtml has a Form and a Submit Button in it to post information about the childModel. [HttpPost] public ActionResult ChildAction(ChildModel childmodel) { ... So, I don't see your point how ParentModel wraps around ChildModel? Could you show the code sample please? Also probably as themarcuz said, everyone handles its own model?

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.
