Hi all!

I am sorry if im asking same thing for the nth time but i can not find the answer to my question...

I have problem adding partial views...

I have One-to-Many relation in the database tables.

My Model is:

using System;
    using System.Collections.Generic;

    public partial class Job
    {
        public Job()
        {
            this.Flights = new HashSet<Flight>();
        }

        public int JobID { get; set; }
        public string JobNumber { get; set; }
        public int ClientID { get; set; }

        public virtual Client Client { get; set; }
        public virtual ICollection<Flight> Flights { get; set; }
    }

My Controller (Create):

/ GET: /Jobs/Create
        public ActionResult Create()
        {
            ViewBag.ClientID = new SelectList(db.Clients, "ClientID", "ClientName");
            return View();
        }

And View (for create Job):

@model AOG.Models.Job

    <div class="form-horizontal">
        <h4>Job</h4>
        <hr />
        @Html.ValidationSummary(true)

        <div class="form-group">
            @Html.LabelFor(model => model.JobNumber, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.JobNumber)
                @Html.ValidationMessageFor(model => model.JobNumber)
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.ClientID, "ClientID", new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.DropDownList("ClientID", String.Empty)
                @Html.ValidationMessageFor(model => model.ClientID)
            </div>
        </div>

        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Create" class="btn btn-default" />
            </div>
        </div>
    </div>

Now if i add partial view (Generated Partial List View) On Create Job Page:

@html.Partial("_PartialFlights");

I get an error: Object reference not set to an instance of an object on

Line 23: @foreach (var item in Model) {

in my partial view. This is the code:

@model IEnumerable<AOG.Models.Flight>
    <table class="table">
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.FlightName)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.FlightETD)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.FlightETA)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Job.JobNumber)
        </th>
        <th></th>
    </tr>
    @foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.FlightName)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.FlightETD)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.FlightETA)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Job.JobNumber)
        </td>
        <td>
            @Html.ActionLink("Edit", "Edit", new { id=item.FlightID }) |
            @Html.ActionLink("Details", "Details", new { id=item.FlightID }) |
            @Html.ActionLink("Delete", "Delete", new { id=item.FlightID })
        </td>
    </tr>
    }
    </table>

How ever If i put this in the details view:

 @foreach (var item in Model.Flights)
    {
        <div>
            <table>
            <tr><th>Flight</th><th>ETD</th><th>ETA</th></tr>
            <tr>
                <td>@Html.DisplayFor(modelItem => item.FlightName)</td>
                <td>@Html.DisplayFor(modelItem => item.FlightETD)</td>
                <td>@Html.DisplayFor(modelItem => item.FlightETA)</td>
                </tr></table>    

     </div>
    }

It shows everything I need, but i want to learn how to do it with the partial views.

Thank you all so much!

Hi. Can you also post the Flight class? And the full Create Job view where you use Html.Partial()

You need to pass the model to the partial, for example:

@Html.Partial("_PartialFlights, partialFlights)
