[Solved] Argument exception when switching to InLine edit mode

[Ola]

Hi,

I am using a Grid and Inline Mode editing. I suddenly get an Argument exception "Value cannot be null or empty." when clicking on the link to edit a cell value. If I change to InForm or Popup mode everything works perfectly, It used to work 5 months ago  and and I have not changed anything in the cshtml file since then. There might have been changes in the web.config. I can't see any changes in the model either and there are no null values there. I have tried to strip down the grid but I still get the error. 

Index.cshtml:

...
        @(Html.Telerik().Grid(Model.ParameterListProcurement)
            .Name("ParameterGridProcurement")
            .DataKeys(keys =>
            {
                keys.Add(c => c.Id).RouteKey("id");
            }
            )
                .DataBinding(dataBinding => dataBinding.Server()
                            .Select("GridSelect", "Parameter", new { mode = GridEditMode.InLine, type = GridButtonType.Image, supplierid = Model.SupplierId })
                                    .Update("Update", "Parameter", new { mode = GridEditMode.InLine, type = GridButtonType.Image, supplierid = Model.SupplierId }))
                    .Columns(columns =>
                    {
                        columns.Bound(p => p.Description).ReadOnly().Width(100).Template(
                        @<text>
                            @item.Description
                        </text>);
                        columns.Bound(p => p).Width(30).Title("Par").EditorTemplateName("Parameter")
                        .Template(
                        @<text>
                                @item.Value
                        </text>);
                        columns.Command(commands =>
                        {
                            commands.Edit().ButtonType(GridButtonType.Image);
                        }).Width(20).Title("");
                    })
                    .Editable(editing => editing.Mode(GridEditMode.InLine))
                    .Footer(false)

        )

...

Editortemplate/Parameter.cshtml:

@model ProOpt.Library.Domain.Parameter
<input id="Value" name="Value" value="@Model.Value.ToString()" />
