MVC: Splitting a list without splitting the dataset

Today I needed to split a list of companies into Companies and Relocation Companies.  The data is in the same table and model, but presentation rules for this project require 2 lists.

SO:

Taking a single dataset from the controller:

        // GET: Companies

        public ActionResult Index()

        {

            return View(db.Companies.ToList());

        }

I took this bit of view/index code from the auto-generated “Code First From Database” tool…

<h3>Companies</h3>

<table class="table">

    <tr>

        <th>

            @Html.DisplayNameFor(model => model.CompanyName)

        </th>

        <th>

            @Html.DisplayNameFor(model => model.isActive)

        </th>

        <th>

            @Html.DisplayNameFor(model => model.isReloCompany)

        </th>

        <th>

            @Html.DisplayNameFor(model => model.ChangedBy)

        </th>

        <th>

            @Html.DisplayNameFor(model => model.LastChangedDate)

        </th>

        <th></th>

    </tr>

    @foreach (var item in Model)

    {

        <tr>

            <td>

                @Html.DisplayFor(modelItem => item.CompanyName)

            </td>

            <td>

                @Html.DisplayFor(modelItem => item.isActive)

            </td>

            <td>

                @Html.DisplayFor(modelItem => item.isReloCompany)

            </td>

            <td>

                @Html.DisplayFor(modelItem => item.ChangedBy)

            </td>

            <td>

                @Html.DisplayFor(modelItem => item.LastChangedDate)

            </td>

            <td>

                @Html.ActionLink("Edit", "Edit", new { id = item.UniqueId }) |

                @Html.ActionLink("Details", "Details", new { id = item.UniqueId })

            </td>

        </tr>

    }

</table>

And I made 2 copies (in my case I will only ever need 2 lists).  I changed the highlighted line in the above to…

    @foreach (var item in Model.Where(d => d.isReloCompany == false).OrderBy(d=>d.CompanyName))

Note that I can add LINQ into the view easily and I did not have to split my list beforehand in the controller.  The second copy of this line has .isReloCompany==true.

How to Convert a Bitmap to an Image

I have seen a lot of crap about how to do this, and there is some very bad advice out there.
This:
Image img = (Image)myBitmap; DOES NOT WORK!

I did find a way to do this in one line of code. Many of the solutions I saw were 50+ lines of code, and most assumed you were saving the bitmap to a file first, which I did not want to do.

Image img = Image.FromHbitmap(bmp.GetHbitmap()); ...

 I was getting this error in Visual Studio 2013 when trying to debug my app.  There was no app_offline.htm file in my Solution Explorer, but if I did a Open folder in file explorer, there it was.

Just delete it.
