I have just returned to using Kendo and put a simple editor on an MVC view. Works fine in Firefox and in IE 10 with compatibility view turned on. With compatibility view turned off the post data for that field is empty.

Is there a specific setting or version that would affect this ?

[Solved] Wrong Data displayed after Insert

Hello dear KendoUI Team!
I've got the following problem:
In one grid, after I insert e new row and click update, the grid does not show the new row. Instead it shows the former first row twice.
After a refresh the new row is shown, so the data is entered correctly on server side.
The grid is ajax bound and inside a tabstrip.
Any Ideas what is going wrong?

Validation problems with form inside Window

I have a kendo grid with a custom toolbar template that has a button to open a kendo window.

This is the code I use to open my window when the above mentioned button is clicked:

var openAssetEditor = function (e) {

var window = $('#AssetEditorPopUp').data("kendoWindow");

window.wrapper.css({

height: 450

});

window.refresh({

url: "/Asset/AssetPopup",

data: { assetId: 0 }

});

window.center();

window.open();

};

Right below the grid I have my Window:

@(Html.Kendo().Window()

.Name("AssetEditorPopUp")

.Title("Asset Editor")

.Content("loading asset info...")

.Draggable(true)

.Modal(true)

.Visible(false)

.Width(950)

)

My controller for the Popup window:

public ActionResult AssetPopup([DataSourceRequest] DataSourceRequest request, int? assetId)

{

return PartialView("~/Views/Asset/AssetPopup.cshtml");

}

I can't seem to validate the form. I always get back that the form is valid even if all the fields are left blank.

[Solved] Using CDN

I am trying to use CDN for my project however when I use the CDN links instead of my kendo files, nothing displays correctly. I also use a custom Kendo css file which I list after at the end.

<link href="http://cdn.kendostatic.com/2013.1.319/styles/kendo.common.min.css" rel="stylesheet" type="text/css" />

<link href="http://cdn.kendostatic.com/2013.1.319/styles/kendo.dataviz.min.css" rel="stylesheet" type="text/css" />

<link href="http://cdn.kendostatic.com/2013.1.319/styles/kendo.default.min.css" rel="stylesheet" type="text/css" />

<link href="http://cdn.kendostatic.com/2013.1.319/styles/kendo.dataviz.default.min.css" rel="stylesheet" type="text/css" />

<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>

<script src="http://cdn.kendostatic.com/2013.1.319/js/kendo.all.min.js"></script>

<script src="http://cdn.kendostatic.com/2013.1.319/js/kendo.aspnetmvc.min.js"></script>

<script src="<%= Url.Content("~/Scripts/jquery.cookie.js") %>"></script>

<link href="<%= Url.Content("~/Content/CustomKendo.css") %>" rel="stylesheet" type="text/css" />

My grids are not returning data or displaying correctly. My drop down list looks like a text box, and my charts are not showing at all. Example of how my grid looks attached. Please help!

[Solved] Add and Update still show entry even when model errors are returned

I am having problems with InLine add and update. If I enter a item that fails the server side validation then the item is still shown as entered/updated. I have followed your examples and looked for threads on this issue, but only found things on PopUp which don't seem to apply here:

The code for add in MVC4 is given below (note: it fails on the ModelState.IsValid, which is correct

[Authorize]

[AcceptVerbs(HttpVerbs.Post)]

[ValidateAntiForgeryToken]

public ActionResult AjaxServiceCreate([DataSourceRequest] DataSourceRequest request, ISmServiceDto newItem, ICreateSmService service)

{

if (newItem != null && ModelState.IsValid)

{

var response = service.Create(newItem);

if (!response.IsValid)

response.CopyErrorsToModelState(ModelState);

}

return Json(new[] { newItem }.ToDataSourceResult(request, ModelState));

}

My razor view is:

@model bool

@{

ViewBag.Title = "Services";

}

<h2>Services</h2>

@*<div id="message" class="Message"></div>*@

@Html.AntiForgeryToken()

@(Html.Kendo().Grid<ServiceLayer.Models.DTOs.SmServiceDto>()

.Name("Services")

.Columns(columns =>

{

columns.Bound(p => p.SmServiceId).Hidden();

columns.Bound(p => p.ShortName);

columns.Bound(p => p.FullName);

columns.Bound(p => p.Locked);

if (@Model)

{

columns.Command(command => { command.Edit(); command.Destroy(); }).Width(172);

}

})

.ToolBar(toolbar =>

{

if (@Model)

{

toolbar.Create();

}

})

.Editable(editable => editable.Mode(GridEditMode.InLine))

.Pageable()

.Sortable()

//.Scrollable()

//.HtmlAttributes(new {style = "height:430px;"})

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(10)

.Events(events => events.Error("error_handler"))

.Model(model =>

{

model.Id(p => p.SmServiceId);

model.Field(x => x.SmServiceId).Editable(false);

model.Field(x => x.Locked).Editable(false);

})

.Create(x => x.Action("AjaxServiceCreate", "Model").Type( HttpVerbs.Post).Data("sendAntiForgery"))

.Read(read => read.Action("AjaxServiceRead", "Model"))

.Update(x => x.Action("AjaxServiceUpdate", "Model").Type( HttpVerbs.Post).Data("sendAntiForgery"))

.Destroy(x => x.Action("AjaxServiceDelete", "Model").Type( HttpVerbs.Post).Data("sendAntiForgery"))

))

@section scripts {

<script type="text/javascript">

function error_handler(e) {

if (e.errors) {

e.preventDefault(); // cancel grid rebind if error occurs

var message = "Errors:\n";

$.each(e.errors, function (key, value) {

if ('errors' in value) {

$.each(value.errors, function () {

message += this + "\n";

});

}

});

alert(message);

}

function sendAntiForgery() {

return { "__RequestVerificationToken": $('input[name=__RequestVerificationToken]').val() };

}

</script>

}

Your help on this matter would be appreciated.

[Solved] Manual data display

I have a kendo combobox created using
an MVC wrapper like so:

@Html.Kendo.ComboBox().Name("Well");

I want to update the data manually
using a json array stored in javascript (not from an ajax query) - I came
across this code which almost works except that I get [object Object] 3 times
in the ComboBox instead of the 'text' value from the json array:

$("#Well").data("kendoComboBox").dataSource.data([{text:
"i1", value: "1"},
{text: "i2", value: "2"},
{text: "i3", value: "3"}]);

$("#Well").data("kendoComboBox").dataSource.query();

<Edit>

Never mind, found the issue. Sorry about that.

</Edit>

Thanks for your help.

[Solved] use of javascript functions

Hello ,
i have another question regarding columns in the grid.
When i have a client template something like this
......
@(Html.Kendo().Grid<MyProject.ViewModels.TestViewModel>()
.Name("Grid")

.Columns(columns =>
{
.columns.Template(x => { }).ClientTemplate("<a href='#'><img src="" alt=""></img></a>").Width(100)
......
}
but is huge on several lines, for example
@"<a class='k-button' href='javascript: void(0)' onclick='doLoading(this)' style='min-width:32px!important'><span class='k-icon k-edit'></span></a>
<a class='k-button' href='javascript: void(0)' onclick='deleteRow(this);return false;' style='min-width:32px!important'><span class='k-icon k-delete'></span></a>"

can i use a javascript function that return all this html string ?

Regards,
Daniel

LoadContentFrom not calling my controller

Hi, I've begun the process of upgrading my MVC Telerik Extension app to Kendo. I am on MVC4 using the server wrappers. It didn't take long before I ran into a perplexing issue.
The first thing I did was upgrade the menu to this:

@( Html.Kendo().Menu()

.Name("Menu")

.Items(menu =>

{

menu.Add().Text("Tasks").Action("Index", "Tasks");

@* Rest eliminated *@

})

)

And I get JS error jQuery(...).kendoMenu is not a function in the browser on this code:

jQuery(function(){jQuery("#Menu").kendoMenu({});});

On that same page is a tabstrip here:

@( Html.Kendo().TabStrip()

.Name("TabStrip")

.Items(parent =>

{

parent.Add()

.Text("My Tasks")

.Selected(true)

.LoadContentFrom("MyTasks", "Tasks");

@* Abbreviated *@

})

)

But this never calls my MyTasks controller. This all worked fine with the Extensions, so I must have a configuration issue, right? What am I doing wrong?

Grid Model With Dictionary or List

My grid model is essentially a collection of dynamic fields that is stored in a Dictonary<string,Values> where Values has a couple properties on it. What would be the best way to iterate thru those values and display them as grid columns? Values will have a value and header text property. I have been searching the forums but have not found anything similar yet.

thanks
