[Solved] MVC3 and Razor Grid editing Problem with Readonly property of a column

[Jyri]

Hi,

Telerik version ASP:NET MVC Version 2010.03.1318.340
ASP.NET MVC3
Razor view engine

When editing (updating) mode=inline the columns I have described as readonly show up correctly as readonly, but do not give the readonly values back to the controller.

when I make a breakpoint on a line (see bold line below) the readonly properties of my terminal object are null.

For not readonly properties all modified data is given back correctly to the controller.
 
I am puzzled, why?

Cheers,
Jyri

My view is Strongly typed
@model IEnumerable<CargoFlowPoco.Terminal>
...
...
@(Html.Telerik().Grid(Model)
        .Name("Grid")
        .DataKeys(keys => keys.Add(o => o.Id))
        .DataBinding(dataBinding => dataBinding
            .Server()
               .Select("Index", "Terminal")
               .Insert("Create", "Terminal")
               .Update("SaveUpdate", "Terminal")
               .Delete("Delete", "Terminal"))
        .Columns(columns =>
        {
            columns.Command(commands =>
            {
                commands.Edit();
                commands.Delete();
            }).Width(200);
            columns.Bound(o => o.Code).Width(100);
            columns.Bound(o => o.RegionName).Width(200);
            columns.Bound(o => o.InsertByUserId).Width(200).ReadOnly();
            columns.Bound(o => o.InsertTimestamp).Format("{0:g}").Width(120).ReadOnly();
        })
        .Sortable(sorting => sorting.Enabled(true))
        .Pageable(paging => paging.Enabled(true))
        .Footer(true)
)


My Terminal Controller

[HttpPost]
        public ActionResult SaveUpdate(int id, Terminal terminal)
        {
            try
            {
                    terminal.UpdateTimestamp = DateTime.Now;
                    _cRepository = new TerminalRepository(_uow);
                    _cRepository.Attach(terminal);
                    _uow.Save();
                    return RedirectToAction("Index");
            }
            catch
            {
                return RedirectToAction("Index");
            }
        }

        public ActionResult Index()
        {
            _cRepository = new TerminalRepository(_uow);
            return View(_cRepository.All());
        }

My objects are POCO and for validation I am using the "buddy object" approach suggested in ScottGu's blog
So I have auto generated class and its buddy class where validations are described

Hi.

Have you found a solution?
I am having the same issue... while "inLine" is okay with ReadOnly properties, having PopUp mode does not format property as ReadOnly.

Any help appreciated...
Thanks 

[Jyri]

My solution was to add hidden fields for read only properties to the view. This worked OK with inline editing.

Actually I solved my problem with a EditorTemplate.

From my class i choose only properties I want to to edit.
Something like this:
Client.cshtml on Shared/EditorTemplates

@model Client
<fieldset>
    @Html.HiddenFor(model => model.Id)
    <table style="border-style: hidden">
        <tr>
            <td style="vertical-align: top">
                <div class="editor-label">
                    @Html.LabelFor(model => model.Code)
                </div>
                <div class="editor-field">
                    @Html.EditorFor(model => model.Code)
                    @Html.ValidationMessageFor(model => model.Code)
                </div>
                <div class="editor-label">
                    @Html.LabelFor(model => model.Name)
                </div>
                <div class="editor-field">
                    @Html.EditorFor(model => model.Name)
                    @Html.ValidationMessageFor(model => model.Name)
                </div>
                <div class="editor-label">
                    @Html.LabelFor(model => model.TaxNumber)
                </div>
                <div class="editor-field">
                    @Html.EditorFor(model => model.TaxNumber)
                    @Html.ValidationMessageFor(model => model.TaxNumber)
                </div>
            </td>
            <td style="vertical-align: top">
                <div class="editor-label">

                    @Html.ValidationMessageFor(model => model.Address)
                </div>
                <div class="editor-label">
                    @Html.LabelFor(model => model.PostalCode)

            Updated = DateTime.Now;
        }
    }
    public class ClientValidator
    {
        [ReadOnly(true)]
        [ScaffoldColumn(false)]
        public object Id { get; set; }

        [Required]
        public object TaxNumber { get; set; }

        [DisplayFormat(DataFormatString = "{0:dd-MM-yyyy HH:mm}")]
        [DataType(DataType.DateTime), Required]
        [ReadOnly(true)]
        public object Inserted { get; set; }

        [DisplayFormat(DataFormatString = "{0:dd-MM-yyyy HH:mm}")]

        [ReadOnly(true)]
        public object Updated { get; set; }

        [ScaffoldColumn(false)]

    }
