问题
Hi I am trying to submit parent and children, I am able to submit the Parent fine but not the children, is there any way to do this ?
this is my code.
@model IECWeb.Models.CurrencyDay
using (Html.BeginForm()) {
@Html.ValidationSummary(true)
<fieldset>
<legend>CurrencyDay</legend>
<div class="editor-label">
@Html.LabelFor(model => model.CurrencyDate)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.CurrencyDate)
@Html.ValidationMessageFor(model => model.CurrencyDate)
</div>
<p />
<table>
<tr>
<th>Currency</th>
<th>Rate</th>
</tr>
@foreach (var item in Model.Currency) {
<tr>
<td>
<div class="editor-field">
@Html.EditorFor(model => item.Name)
@Html.ValidationMessageFor(model => item.Name)
</div>
</td>
<td>
<div class="editor-field">
@Html.EditorFor(model => item.Rate)
@Html.ValidationMessageFor(model => item.Rate)
</div>
</td>
</tr>
}
</table>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
When I submit I get the CurrencyDay object But not the list of Currency
Thanks sushiBite.

I would recommend you using editor templates instead of writing loops in your views:
<table>
<tr>
<th>Currency</th>
<th>Rate</th>
</tr>
@Html.EditorFor(x => x.Currency)
</table>
and then in the corresponding editor template which will be rendered for each element of the currency collection (~/Views/Shared/EditorTemplates/CurrencyViewModel.cshtml
):
@model CurrencyViewModel
<tr>
<td>
<div class="editor-field">
@Html.EditorFor(model => model.Name)
@Html.ValidationMessageFor(model => model.Name)
</div>
</td>
<td>
<div class="editor-field">
@Html.EditorFor(model => model.Rate)
@Html.ValidationMessageFor(model => model.Rate)
</div>
</td>
</tr>
Notice that the name and the location of the editor template is important. By convention the location should be either ~/Views/SomeController/EditorTemplates
(if the template is reused between actions of the controller) or more globally ~/Views/Shared/EditorTemplates
. The name of the editor template should be the name of the type of each element of the collection you are iterating over.
