Problem with using CellEdit on next cell

Hi!
I use a grid with incell edit option. I try to set focus and edit the next cell with tab key pressed on prev.

$('#grid div table tr td input').live('keydown', function(event) {
if (event.which == 9) {
var grid = $("#grid").data("kendoGrid");
var $td = $(this).parent();
grid.editCell($td.next());
}
});
something like this.
But in this case old input is not closed.
I try new code
$('#grid div table tr td input').live('keydown', function(event) {
if (event.which == 9) {
var grid = $("#grid").data("kendoGrid");
var $td = $(this).parent();
grid.closeCell();
grid.editCell($td.next());
}
});
In this case old input closes, but entered value doesn't saved in a cell.
How can I edit next cell with correct close previous input?

Update on IE is different from FireFox

Hi,

I'm kinda new to Kendo UI so its possible I've missed it in the discussions here.

We're building a PoC with Kendo UI and MVC3 in Visual Studio 2010. What I noticed today is that an 'inline' edit in the Kendo Grid leads to different results in IE9 and FireFox. When I edit a line in IE9, update it to the server the data is persisted correctly in the DB and the screen show the new value. After a refresh however the old data is back. Closing IE9 all together and restarting the App gives me the data from DB correctly.

If I do the same in FireFox after a refresh the data is shown correctly.

When I empty the cache in IE9 before the refresh the behavior is as expected (showing the correct information from the DB).

Here's some of my code:
The Update Method in the Controller

public HttpResponseMessage Update(int id)

{

HttpResponseMessage response = new HttpResponseMessage();

using(var entity = VMProjectRegel.GetById(this, Id))

{

entity.Aantal = Convert.ToInt32(Request["Aantal"]);

entity.Prijs = Convert.ToDecimal(Request["Prijs"]);

entity.BTW = Convert.ToDecimal(Request["BTW"]);

entity.CreatedOn = Convert.ToDateTime(Request["CreatedOn"]);

entity.CreatedBy = Convert.ToInt32(Request["CreatedBy"]);

entity.ChangedOn = Convert.ToDateTime(Request["ChangedOn"]);

entity.ChangedBy = Convert.ToInt32(Request["ChangedBy"]);

ORMSession.SaveChanges();

response.StatusCode = HttpStatusCode.OK;

}

return response;

}

The view:

<script src="@Url.Content("~/DataSources/ProjectOnderhoudDataSource.generated.js")" type="text/javascript"></script>

<div id="projectEditForm">

<input id="DatumAanvang" data-bind="value: selectedProject.DatumAanvang" />

<hr />

<div id="projectRegelGrid" />

<script type="text/javascript">

$(function ()

{

$("#DatumAanvang").width(220).kendoDatePicker();

ProjectOnderhoudDataSource.bind("change", function (data)

{

ProjectOnderhoudViewModel.set("selectedProject", this.view()[0]);

});

ProjectOnderhoudDataSource.read();

kendo.bind($("#projectEditForm"), ProjectOnderhoudViewModel);

ProjectOnderhoudProjectRegelListDataSource.options.transport.read.parentId = 1;

$("#projectRegelGrid").kendoGrid

({

columns:

[

{ field: "Aantal", title: "Aantal" },

{ field: "Prijs", title: "Prijs" },

{ field: "BTW", title: "BTW" },

{ field: "CreatedOn", title: "Datum aangemaakt", template: '#= kendo.toString(CreatedOn, "dd MMMM yyyy") #' },

{ field: "ChangedOn", title: "Datum gewijzigd", format: "{0:dd MM yyyy}" },

{ command: ["edit", "destroy"], title: " ", width: "210px" }

],

editable: "inline",

deletabled: true,

pageable: true,

sortable: true,

dataSource: ProjectOnderhoudProjectRegelListDataSource,

pageSize: 3,

serverPaging: false

});

</script>

</div>

Paul.

Grid column template breaks Create action

I have a column field named Email in a datasource of Users. When I apply a template to the field (i.e. "<a href="mailto:#=Email#">#=Email#</a>"), and I click the Add new record button on the toolbar, I get an error stating that the field named Email is undefined. When I remove the template, the create action works like it should.

Here is the code that recreates the error:

/// <reference path="_references.js" />

var users = [

{ Id: '0', FirstName: 'Bruce', MiddleName: 'Ethan', LastName: 'Fletcher', Email: 'fake.email@nowhere.com', BirthDate: '1/3/1986' },

{ Id: '1', FirstName: 'Sally', MiddleName: 'Mary', LastName: 'Holland', Email: 'fake.email@nowhere.com', BirthDate: '7/12/1990' }

];

$(function () {

var userViewModel = new kendo.data.Model.define({

id: 'Id',

fields: {

Id: { editable: false, defaultValue: '9999' },

FirstName: { editable: true, nullable: false, validation: { required: true} },

LastName: { editable: true, nullable: false, validation: { required: true} },

MiddleName: { editable: true, nullable: false },

Email: { editable: true, nullable: false, type: 'email', validation: { required: true} },

BirthDate: { editable: true, nullable: false, type: 'date' }

}

});

var userDataSource = new kendo.data.DataSource({

data: users,

schema: {

model: userViewModel

},

pageSize: 5

});

$('#user_grid').kendoGrid({

dataSource: userDataSource,

toolbar: [{ name: 'create'}],

columns: [

{ field: 'FirstName', title: 'First Name' },

{ field: 'MiddleName', title: 'Middle Name' },

{ field: 'LastName', title: 'Last Name' },

{ field: 'Email', title: 'Email Address', template: '<a href="mailto:#=Email#">#=Email#</a>', encoded: false }, // !! apply a template to break create !!

{ field: 'BirthDate', title: 'Birth Date', format: '{0:MM/dd/yyyy}' },

{ command: [{ name: 'edit', text: '' }, { name: 'destroy', text: ''}], title: '', width: '86px' }

],

pageable: {

refresh: true

},

editable: 'popup'

});

Binding E-mail field to href / mailto

Is there a way to bind an observable e-mail address to the href attribute of an element? I tried the following:
<a data-bind="{attr:{href:Email},text:Email}"></a>

But of course this lacks the needed "mailto:".

I know in Knockout you can do it like this:
<a data-bind="{attr:{href:'mailto:'+Email},text:Email}"></a>

I tried that in Kendo and it failed with an "Unrecognized string" error.

What's the best way to handle this type of binding in Kendo's MVVM setup?

Unable to remove item from kendo dropdownlist programmatically

The following two methods for trying to programatically remove an item from a kendo dropdownlist were taken directly from Kendo forums but did not work. Both methods caused the dropdownlist to vanish entirely from the UI. The dropdownlist is defined in the header of a kendo grid control. I have verified that the _selectedLoosePartIndex value is good. Have to say that so far this product has cost me weeks of additional programing time trying to do the most simple tasks imaginable. I have no idea why it is such a popular product. I really do not believe that you guys have even attempted to thoroughly test the API in real world applications.

//Method one:

var data = $('#AvailableLooseParts').kendoDropDownList().data("kendoDropDownList").dataSource.data();

data = data.splice(_selectedLoosePartIndex, 1);

$('#AvailableLooseParts').kendoDropDownList().data("kendoDropDownList").dataSource.data(data);

// Method two:

var ddl = $('#AvailableLooseParts').data("kendoDropDownList");

var itemToRemove = ddl.dataSource.at(_selectedLoosePartIndex);

ddl.dataSource.remove(itemToRemove);

ddl.select(0);

Paging/filtering in query string and other parameters in body?

I have a fairly complex report I am creating that requires posting a bunch of JSON to a server. I have this up and running just fine with a data source. What I'm trying to do is to add server-side paging, into this process and am unsure how to proceed.

I thought it might make sense to put the paging in the query string of the URL that I'm posting the JSON to, but I can't figure out how to get the data source to accomplish this. I have turned on the server paging and set the page size properly. Does Kendo see that my read endpoint is a "POST" endpoint and just ignore adding anything to the query string? Is there a way to force it to add the current page size and page to the read URL?
