在MVC 5中,如何将表对象数据作为列表传递给Controller View Model? [英] In MVC 5 how to pass table Object data as a list to Controller View Model?
问题描述
我的控制器 ItemRequestViewModel
为空&问题是它没有从视图向控制器传递任何值,但是当我传递 List< string>
时,它显示了一个行值.我只是不能将多个对象传递给Controllers ViewModel.我也尝试通过作为 List< ItemRequestViewModel reqItem>
传递,但似乎没有希望.
My Controller ItemRequestViewModel
is null & the issue is it didn't pass any value from view to controller but when i pass a List<string>
it shows one Row Value. I just can't pass multiple object to Controllers ViewModel. i have tried by passing as a List<ItemRequestViewModel reqItem>
as well but it seems no hope.
我的控制器
public ActionResult ReqNotifyApprove(List<ItemRequestViewModel> reqItem)
{
return null;
}
我的观点
@model IEnumerable<Management_System.ViewModels.ItemRequestViewModel>
@using (Html.BeginForm("ReqNotifyApprove",
"RequestedItems",
FormMethod.Post,
new { id = "ReqItemApproveForm" }))
{
<table class="table table-bordered results">
<thead>
<tr>
<th>ID</th>
<th>ITEM ID</th>
<th>DESCRIPTION</th>
<th>UOM</th>
<th>AVL QTY</th>
<th>REQ QTY</th>
<th>AUTH QTY</th>
</tr>
</thead>
<tbody>
@foreach (var item in Model)
{
<tr>
<th>
@Html.DisplayFor(modelItem => item.Id)
@Html.HiddenFor(modelItem => item.Id, new { name = "Id" })
</th>
<th>
@Html.DisplayFor(modelItem => item.PDT_CODE)
</th>
<td>
@Html.DisplayFor(modelItem => item.PDT_NAME)
</td>
<td>
@Html.DisplayFor(modelItem => item.UOM_SNAME)
</td>
<td>
@Html.DisplayFor(modelItem => item.AvailableQty)
</td>
<td>
@Html.DisplayFor(modelItem => item.ISS_QTY)
</td>
<td>
<input type="number" id="ApprovedQuantity" name="ApprovedQuantity" class="form-control" min="0" style="width: 80px;">
</td>
</tr>
}
</tbody>
</table>
<div>
<input class="btn btn-lg btn-success" type="submit" value="Approve" />
</div>
}
我已经尝试了不同的数据绑定,但是没有希望.
I have already tried different Data binding as well but no hope.
推荐答案
您的方法遇到的问题是您将name属性固定设置为"Id".MVC绑定集合的方式是通过在HTML名称属性中添加"[index]"作为前缀.您可以在此处找到有关它的更多详细信息-https://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx/
The problem on your approach, is the name attribute that you fixed set to "Id". The way MVC binds a collection, is by adding "[index]" as a prefix to the HTML name attribute. You can find more details about it here - https://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx/
因此,如果您删除此 new {name ="Id"}
,并使用 for
而不是 foreach
,您的剃须刀将类似于:
So, if you remove this new { name = "Id" }
, and use a for
instead of foreach
,
your Razor will be something like:
@for (int i=0; i < Model.Count; i++)
{
@Html.DisplayFor(modelItem => Model[i].Id)
@Html.HiddenFor(modelItem => Model[i].Id)
....
}
隐藏输入的结果应类似于:
And the result of the hidden input should be something like:
<input type='hidden' name="[0].Id" id="0__Id" />
<input type='hidden' name="[1].Id" id="1__Id" />
<input type='hidden' name="[2].Id" id="2__Id" />
