Hey Guys...so trying to get my head around MVC

My Index for holiday page is linked to the model

@model HolidayBookingApp.Models.HolidayList

Im trying to pull the value of Holidays remaining from the HList4DD (HolidayListForDropDown) which is coming from the HolidayList.cs page.

I can get it through...

@foreach (var item in Model.HList4DD)
{
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.PersonId)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.HolidayDate)
        </td>
        <td>
        @Html.DisplayFor(modelItem => item.Person.HolidaysRemaining)
        </td>

Although this displays the holidays remaining for every holiday booked. So if 20 holidays is the limit (4 booked and 16 remaining) this will produce a list of the dates of holidays booked i.e 4 records stating which date is booked, but it will show the '16' holidays remaining 4 times as well.

Yes, this is because it is inside the for loop but I tried to display it on its own and it didnt work

@Html.DisplayFor(model => model.HList4DD.//what do i add here?

Also tried to add

Person person = new Person();
            currentHolidaysRemaining = person.HolidaysRemaining;

to the HolidayList. cs then in the view do

@Html.DisplayFor(model => model.currentHolidaysRemaining)

but its not pulling across the correct value, just returning 0

please advise....thanks

Im now using

bool isFirst = true;
@int remainingHolidays = 0;
 
@foreach (var item in Model.HList4DD)
{
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.PersonId)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.HolidayDate)
        </td>
   
 
   if (isFirst)
   {
      remainingHolidays = item.Person.HolidaysRemaining;
      isFirst = false;
   }
        
        <td>
            @Html.ActionLink("Edit", "Edit", new { id = item.Id }) |
            @Html.ActionLink("Details", "Details", new { id = item.Id }) |
            @Html.ActionLink("Delete", "Delete", new { id = item.Id })
        </td>
    </tr>}
        
    
    <tr>
      <div class="editor-label">
         @*   @Html.LabelFor(model => model.PList4DD, "Person")*@
        </div>
 
        <div class="editor-field">
       
             <form action ="/Holidays/Index" id="some" method="post"> 
 
            @* *WORKING VERSION**@ @Html.DropDownListFor(model => model.HList4DD.First().HolidayDate, new SelectList(Model.PList4DD, "Id", "Name", Model.currentPersonID), "--select--")
        
 
       <script>
           function updateFormEnabled() 
           {
               if (verifyAdSettings()) 
               {
                   $('#sbmt').removeAttr('disabled');
               }
               else 
               {
                   $('#sbmt').attr('disabled', 'disabled');
               }
           }
 
           function verifyAdSettings() 
           {
               if ($('#HolidayDate').val() != '') 
               {
                   return true;
 
               }
               else 
               {
                   return false;
               }
           }
 

           $('#HolidayDate').change(updateFormEnabled);         
           </script>
 
      <td>
      @remainingHolidays.ToString()
   </td>
               
             <input type="submit" id= "sbmt" name="ViewHolidaysDD" value="View"/>
              </form>
         
  <script>
      $('#sbmt').attr('disabled', '');
        </script>
 
</table>

the @remainingHolidays.ToString() 5 lines or so up from the bottom is saying it doesnt exist in the current context?

Maybe you are over thinking the problem.

</td>
<td>
@Html.DisplayFor(modelItem => item.HolidayDate)
</td>

<td>
@Html.DisplayFor(modelItem => item.Person.HolidaysRemaining)
</td>

Then you just increment the value of i.

Hope this helps.

[edit] fixed formating.
