There is something simple I don't understand with ChildActions.
I've created a simple View for a model, that loads a child action with a form.
The child action has another model than its parent, with a different id property.
Html.HiddenFor(m => m.Id) still outputs the parents id, although @Model.id outputs the correct value!
Can't I reliably use the Helper methods in ChildActions, or is this a known bug?
HomeController
public class HomeController : Controller
{
public ActionResult Index()
{
var model = new Models.HomeModel { id = 1, message = "bugmodel" };
return View(model);
}
[HttpGet]
[ChildActionOnly]
public ActionResult Child(int id)
{
var model = new Models.HomeChildModel { id = 100, parentId = id, childMessage = "My Child message" };
return PartialView(model);
}
[HttpPost]
[ActionName("Child")]
[ValidateAntiForgeryToken()]
public ActionResult ChildPost(Models.HomeChildModel model)
{
return RedirectToAction("Index");
}
}
Models
public class HomeModel
{
public int id { get; set; }
public string message { get; set; }
}
public class HomeChildModel
{
public int id { get; set; }
public int parentId { get; set; }
public string childMessage { get; set; }
}
Home view
@model ChildActionBug.Models.HomeModel
@{
ViewBag.Title = "Index";
}
<h2>Index</h2>
@Html.DisplayFor(m=>m.id)
@Html.DisplayFor(m=>m.message)
@Html.Action("Child", new { id = Model.id })
**Child view**
@model ChildActionBug.Models.HomeChildModel
<h3>Child here</h3>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
@Html.HiddenFor(m=>m.id)
@Html.HiddenFor(m=>m.parentId)
@Html.EditorFor(m=>m.childMessage)
<div>Child Model ID: @Model.id</div>
<button type="submit">Save</button>
}
