How to get the value from the <form> tag?

Question

Based on my colleague’s code, he passes the HTML attributes to his form declaration in the view using BeginForm, and the resulting HTML looks like this:

<form action="/Reviewer/Complete" ipbID="16743" method="post">

How can I get ipbID in my controller code? I'm trying to

HttpContext.Request.QueryString["ipbID"]

... and ...

Request.Form["ipbID"]

and I even went into debugging and went through each part of Request.Form to find out if this value was somehow. Should you use such values ​​in a form tag? Any help is appreciated. Thank.

UPDATE: I must inform you that this form applies to the cell. Cells are in dataTable. When I use it, the first value that was hidden, but not one of the following, is returned.

UPDATE 2: View

<% Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<PTA.Models.IPB>>" %>

<%@ Import Namespace="PTA.Helpers"%>

<b>Assigned IPBs</b>

<script type="text/javascript" charset="utf-8">
  $(document).ready(function() {
    $('#sharedIPBGrid').dataTable();
  });
</script>

<%
if (Model != null && Model.Count() > 0)
{
%>
<table id="sharedIPBGrid" class="display">
  <thead>
    <tr>
      <th>
        <%=Html.LabelFor(m => m.FirstOrDefault().IPBName) %>
      </th>
      <th>
        <%=Html.LabelFor(m => m.FirstOrDefault().Status) %>
      </th>
      <th>
        <%=Html.LabelFor(m => m.FirstOrDefault().PubDate) %>
      </th>
      <th>
        <%=Html.LabelFor(m => m.FirstOrDefault().ChangeDate) %>
      </th>
      <th>
        <%=Html.LabelFor(m => m.FirstOrDefault().Priority) %>
      </th>
      <th>
        <%=Html.LabelFor(m => m.FirstOrDefault().Errors) %>
      </th>
      <th>
        Start
      </th>
      <th>
        Stop
      </th>
      <th>
        Complete
      </th>
    </tr>
  </thead>
  <tbody>
    <tr>
<%
  foreach(IPB ipb in Model)
  {
%>
      //Ignoring everything except for the Complete button as there a lot of logic in there.
      <td>
<%
         if (ipb.StatusID == (int)PTA.Helpers.Constants.State.InWorkActive)
         {
           using (Html.BeginForm("Complete", "Reviewer", FormMethod.Post, new {ipbID = ipb.ID}))
           {
%>
             <%=Html.Hidden("ipbID", ipb.ID)%>
             <input type="submit" id="btnComplete" value="Complete" />
<%
           }
         }
%>
      </td>
<%
  }
%>
    </tr>
  </tbody>
</table>
<%
}
else
{
  Response.Write("No IPBs found!");
}
%>

, . . ipbID, form, , HTML. , .

, . :

<form action="/Reviewer/Complete" ipbID="16743" method="post">

Try:

<form action="/Reviewer/Complete" method="post">
    <input type="hidden" name="ipbID" value="16743" />

Request["ipbID"] ipbID .
