I've come up with problem, when trying to fill data to my model. I have an "Resource" entity, which can have no-to-many "attributes". I have templates set up, which holds names for those attributes. When Resource is created, user chooses on of templates, then Attributes are created(empty) and program generates form for those attributes.
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
@Html.HiddenFor(Model => Model.Resource)
@for (int i = 0; i < Model.Attributes.Count(); i++)
{
<div class="form-group">
@*Html.LabelFor(d => d.Attributes.ToArray()[i].Name, htmlAttributes: new { @class = "control-label col-md-2" })*@
<h4>@Html.Raw(Model.Attributes.ToList()[i].Name)</h4>
<div class="col-md-10">
@Html.TextBoxFor(Model => Model.Attributes.ToList()[i].Value, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(Model => Model.Attributes.ToList()[i].Value, "", new { @class = "text-danger" })
</div>
</div>
}
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Save" class="btn btn-default" />
</div>
</div>
</div>
}
This form uses this View model:
public class ResourceAttributesViewModel
{
public virtual Resource Resource { get; set; }
public virtual ICollection<_Attribute> Attributes { get; set; }
}
problem is that when i hit "submit" button, it gives me view model with null Resource and Attributes properties
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Fill(ResourceAttributesViewModel AttributeSet)
{
if(ModelState.IsValid)
{
foreach (var attr in AttributeSet.Attributes)
{
db.Entry(attr).State = EntityState.Modified;
db.SaveChanges();
}
return RedirectToAction("Index");
}
return View(AttributeSet);
}
if it helps, there is POST string sent by browser
