Hello!
I have the following Model
public class Mandant
{
public Guid Id { get; set; }
public string Name { get; set; }
public DateTime ErzeugtAm { get; set; }
public DateTime AktualisiertAm { get; set; }
public string ErzeugtVon { get; set; }
public string StrasenAdresse { get; set; }
public string Postfach { get; set; }
public string Plz { get; set; }
public string Stadt { get; set; }
public string Staat { get; set; }
}
A Grid is constructed to list and edit the Mandant Model
I have the following Model
public class Mandant
{
public Guid Id { get; set; }
public string Name { get; set; }
public DateTime ErzeugtAm { get; set; }
public DateTime AktualisiertAm { get; set; }
public string ErzeugtVon { get; set; }
public string StrasenAdresse { get; set; }
public string Postfach { get; set; }
public string Plz { get; set; }
public string Stadt { get; set; }
public string Staat { get; set; }
}
A Grid is constructed to list and edit the Mandant Model
<%=html.Kendo().Grid<MandantEntity>()
.Name("Mandanten")
.ToolBar(toolbar => toolbar.Create())
.Pageable(pageable => pageable.ButtonCount(5))
.Sortable(sortable => sortable.AllowUnsort(true).SortMode(GridSortMode.SingleColumn))
.Filterable()
.Editable(editable => editable.Mode(GridEditMode.InLine))
.DataSource(dataSource => dataSource.Ajax()
.PageSize(5)
.Read(read => read.Action("Read", "Mandant"))
.Update(update => update.Action("Update", "Mandant"))
.Create(create => create.Action("Create", "Mandant"))
.Model(model =>
{
model.Id(p => p.Id);
model.Field(field => field.Id).DefaultValue(Guid.NewGuid());
model.Field(field => field.ErzeugtAm).DefaultValue(DateTime.MinValue);
model.Field(field => field.AktualisiertAm).DefaultValue(DateTime.MinValue);
model.Field(field => field.ErzeugtVon).DefaultValue(Guid.NewGuid());
model.Field(field => field.AktualisiertVon).DefaultValue(Guid.NewGuid());
}))
.Columns(columns =>
{
columns.Bound(o => o.Name).Width(180);
columns.Bound(o => o.StrassenAdresse).Width(180);
columns.Bound(o => o.Postfach).Width(50);
columns.Bound(o => o.Plz).Width(60);
columns.Bound(o => o.Stadt).Width(60);
columns.Bound(o => o.Staat).Width(60);
columns.Command(command => command.Edit()).Width(200);
})
%>
As above, the code works great. I can load the view, edit existing elements, and create new ones.
When I change the Mode to GridEditMode.PopUp, I can no longer load the view. I get instead the following error.
I would really appreciate your help on this!

Hi Klaus,
From the provided information it seems that you are passing "Guid" object as default value for properties of type "string" which is invalid configuration. I would suggest to use the ToString method to convert the "Guid" object to the correct type:

Hi Vladimir,
I made a mistake copying the code. ErzeugtVon as well as AktualisiertVon are both Guids. My bad.
I have created a test project that reproduces the issue. The zip is 20 MB large. I am unable to attach it to my reply, how can I send you the test project?
Thank you very much for your help!

There are several ways you can proceed:
- Open a new support thread - support threads have 20mb limit for file uploads
- Upload the project to some public FTP and provide the download link here
- Remove all unrelated widgets, packages and files from the project to reduce it's size and attach it to current thread

I'm having the same problem. Inline edit succeeds. The following configuration throws this error when loading.
The model item passed into the dictionary is of type 'System.Guid', but this dictionary requires a model item of type 'System.String'.

{
columns.Bound(p => p.ContextUid).Visible(false);

columns.Bound(p => p.StatusId).Title("Status");
columns.Bound(p => p.Value);
columns.Bound(p => p.Description);
columns.Bound(p => p.Title);
columns.Command(command => { command.Edit(); command.Destroy(); }).Title("Action").Width(200);
})

After further investigation it seems that the issue comes from the default EditorTemplate for this field String.cshtml) which accepts model of type String. I would suggest to modify the String editor template to accept model of type object instead:
@model object@Html.TextBoxFor(model => model, new {@class="k-textbox" })Kind Regards,

That solution doesn't work for me. It throws a different error on
@Html.TextBoxFor(model => model, new { @class = "k-textbox" })
ArgumentException was unhandled by user code
Value cannont be null or empty
Actually what I really want to have is a good simple example of Kendo Grid actions opening a Kendo Window and passing the ID for the selected row to the window so it shows the correct data for the selected row. The follow code is from my Index.cshtml. I have a button on grid for chosing the row and opening the window. Just can't make the link to pass the Id for the dataitem to the window. And the .LoadContentFrom(Url.Action("Details", "Context", new { ID = ViewData["ID"] })) doesn't trigger.
