数据不传递给控制器 [英] Data Not Pass to Controller

问题描述

我正在显示数据列表，点击提交按钮，数据应该转到特定控制器，但是我不能这样做。以下是我正在显示数据的部分视图：

I am displaying list of data now on click of submit button the data should go to the Specific Controller but I am not able to do that. Below is the Partial View on which I am displaying data:

@model IEnumerable<WebApplication1.Models.TicketDetails>

@using (Html.BeginForm("SubmitHours", "TicketDetails", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    if (Model.Count() > 0)
    {
        <hr />
        <table cellpadding="0" cellspacing="0">
            <tr>
                <th>Ticket No.</th>
                <th>Summary</th>
                <th>Status</th>
                <th>Action Date</th>
                <th>Billable Hours</th>
            </tr>
            @foreach (var ticketdata in Model)
            {
                <tr>
                    <td>@Html.DisplayFor(modelitem => ticketdata.TicketDetailsGuid)</td>
                    <td>@Html.DisplayFor(modelitem => ticketdata.Summary)</td>
                    <td>@Html.DisplayFor(modelitem => ticketdata.CAStatus)</td>
                    <td>@Html.DisplayFor(modelitem => ticketdata.ActionDate)</td>
                    <td>@Html.TextBox("Comment", null, new { @class = "form-control" })  </td>
                </tr>
            }

        </table>

    }
    <input type="submit" value="Submit" />
    @*<input type="button" value="Submit" onclick="location.href='@Url.Action("SubmitHours", "TicketDetails")'" />*@
}

以下数据显示的控制器如下：

The controller from which above data is display is given below:

public ActionResult Index()
        {
            List<TicketDetails> _TicketDetails = new List<TicketDetails>();
            _TicketDetails = (from ticketdata in _entities.AccMng_TicketDetails.AsEnumerable()
                                     select new TicketDetails
                                     {TicketDetailsGuid = ticketdata.TicketDetailsGuid,
                                      ActionBy = ticketdata.ActionBy,
                                     CAStatus = ticketdata.CAStatus,
                                     Comment = ticketdata.Comment,
                                     Summary = ticketdata.Summary}).ToList();

            return View(_TicketDetails);
        }

现在我只想将该部分数据发送到特定控制器，但是数据不到：

Now here I just want to send that Partial data to a Specific controller but that data not comes:

        [HttpPost]
        public ActionResult SubmitHours(List<AccMng_TicketDetails> _AccMng_TicketDetails)
        {
            return View(_AccMng_TicketDetails);
        }

推荐答案

@Leonardo说，最少使用List而不是IEnumerable作为模型定义来使用基于索引的方法。如果您只想回传每行的注释，请将注释框更改为基于表达式的帮助器，并为GUID添加隐藏字段（因此将其发回控制器）。

First, I would recommend at least use List instead of IEnumerable as your model definition to use the index-based approach, as @Leonardo said. If you are just trying to only pass back the comments for each row, change the comment box to an expression-based helper, and add a hidden field for the GUID (so it posts back to the controller).

@for (var i = 0; i < Model.Count; i++)
{
     <tr>
       <td>
         @Html.DisplayFor(m => m[i].TicketDetailsGuid)
         @Html.HiddenFor(m => m[i].TicketDetailsGuid)
       </td>
       <td>@Html.DisplayFor(m => m[i].Summary)</td>
       <td>@Html.DisplayFor(m => m[i].CAStatus)</td>
       <td>@Html.DisplayFor(m => m[i].ActionDate)</td>
       <td>@Html.TextBoxFor(m => m[i].Comment, new { @class = "form-control" })  </td>
     </tr>
}

当页面发回时，它将使用TicketDetailsGuid回发一个对象列表，仅填写评论字段（因为它们是用户界面中的输入）。

When the page posts back, it will postback a list of objects with TicketDetailsGuid and Comment fields populated only (because they are inputs in the UI).
