Set cancel option on a grid that has already been initialized

Is there a way to set the cancel option on a grid that has already been initialized?

I'm using the serverside MVC wrapper and have this:
.Events(events => events.Cancel("function() {alert('hi');}"))

Clientside I tried:
$("#grdTest").kendoGrid({ cancel: function () { alert("canceled"); } });
and
$kendoGrid = $("#grdTest").data("kendoGrid");
$kendoGrid.options.cancel = function () {
alert('Canceled');
};

Editor removes src attribute in IE8

I'm using the javascript version of the KendoUI Editor. I've tried loading the editor with this in the text field:
<img src="someimagehere.png" alt="" />

After the editor loads, the html says the field has this:
<img alt="" />

This only happens when I'm working in IE8. What's happening?

Splitter script error on window resize on IE 9 - when splitter is removed from DOM and added again dynamically

Hi,

In a MVC4 application I am working, I have some menu links, clicking on these links, I load the relevant page as an ajax partial view below the menu links.
One of the partial views contains a splitter. When I load this partial view containing splitter and navigate to other partial views clicking on other links, and if I come back to the view with the splitter partial view - on window resize the scripts throw an error saying that 'offsetWidth' is null. This happens on IE 9.0 only

Environment
Browser: IE 9.0
Kendo Version: 2013.2.918.340

I have put up a simple mvc4 application demonstrating that.
Steps to reproduce :
1) Click on the link 'Load splitter view below' (Loads a view with splitter beneath the link)
2) Click on the link 'Load non splitter view below' (Replaces the splitter view with a non splitter view)
3) Click on the link 'Load splitter view below' (Loads the splitter view again)
4) Resize the browser window, then the script breaks saying 'offsetWidth' is null. Resizing the window is triggering resize event on splitter, where it is breaking

Can you please see if this is a real issue or if I am missing out anything here ?

MVC Grid not populating from datasource

Hi All,

I'm new to KendoUI so please bear with me. I've a Kendo gird on a view as below:

(I've taken out the extra CRUD lines for clarity as I've not got as far as implementing them yet).

@using Kendo.Mvc.UI

@using MvcApplication2.Models

@{

ViewBag.Title = "Index";

}

<h2>Index</h2>

@(Html.Kendo().Grid<MerchantStore>()

.Name("grid")

.Columns(columns =>

{

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

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

columns.Bound(p => p.Address1);

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

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

})

.ToolBar(toolbar => toolbar.Create())

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

.Pageable()

.Sortable()

.Scrollable()

// .HtmlAttributes(new { style = "height:1430px;" })

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(20)

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

.Model(model => model.Id(p => p.MerchantStoreId))

.Read(read => read.Action("Read", "Home"))

)

<script type="text/javascript">

function error_handler(e) {

if (e.errors) {

var message = "Errors:\n";

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

if ('errors' in value) {

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

message += this + "\n";

});

}

});

alert(message);

}

</script>

I'm trying to hook up the controller to return a json result provided by a wcf webservices. As below:

public ActionResult Read([DataSourceRequest]DataSourceRequest request)

{

var client = new WebClient();

return View("Index", Json(

client.DownloadString("http://localhost:11462/Service1.svc/rest/ListMerchantStore" +

"?merchantId=10000"), JsonRequestBehavior.AllowGet));

}

but I just get an empty grid. The json looks like:

{"d":[{"__type":"MerchantStoreData:#WcfServiceLibrary1","Address1":"Add1","Address2":null,"Address3":null,"CountryId":826,"CountyState":"","Deleted":false,"EmailAddress":null,"MerchantId":10000,"MerchantIndustryId":1001,"MerchantStoreId":10213,"MerchantStoreKey":"654321","Name":"TEST","PostZipCode":null,"StatusId":0,"TelephoneNumber":null,"TownCity":"City"},{"__type":"MerchantStoreData:#WcfServiceLibrary1","Address1":"Add1","Address2":"Add2","Address3":"Add3","CountryId":826,"CountyState":"","Deleted":false,"EmailAddress":"a@a.a","MerchantId":10000,"MerchantIndustryId":1001,"MerchantStoreId":10214,"MerchantStoreKey":"654321","Name":"TEST","PostZipCode":"","StatusId":1,"TelephoneNumber":"123456","TownCity":"City"}]}

Please can someone kindly point out where i'm going wrong.

Many Thanks

View scrolling locks up, unlocks on drawer show+hide

I've distilled the problem into a jsfiddle here: http://jsfiddle.net/dTBN6/6/

You can reproduce the problem by doing the following steps :

Click the "To page 2" button
Resize your window so content is long enough to allow scrolling
Scroll down a bit
Open drawer and go back to page 1
Click the "To page 2" button again
Attempt to scroll - the view's scrolling is locked
Open drawer. Then close it.
Attempt to scroll - it works
Repeat from step 4

If you access page 2 via the link in the drawer, scrolling does not lock up.

What gets triggered when the drawer is shown / hidden that causes the scrolling to unlock?
Can I trigger this manually in page two's "show" event handler?
Is there anyway to fix this?

Append HTML on any Kendo control appears without design

Hello
I have the following drawer

<div data-role="drawer" id="left-drawer" data-title="Global Menu">

<header data-role="header">

<div data-role="navbar">

<span data-role="view-title"></span>

</div>

</header>

<ul data-role="listview" data-type="group">

<li>Global Menu

<ul>

<li data-icon="share"><a href="#drawer-home" data-transition="none">Inbox</a></li>

<li data-icon="share"><a href="#drawer-starred" data-transition="none">Starred Items</a></li>

</ul>

</li>

<li>Sub Menu

<ul id="ResultDiv2">

</ul>

</li>

</ul>

</div>

<div data-role="view" id="about" data-layout="drawer-layout" data-title="About">

about dummy text

</div>

<script>

new kendo.mobile.Application();

</script>

When you bind the drawer from inside Document.Ready everything is working fine and the design appears correctly, but if you bind the drawer on any event like click then the design will not appear correctly.

Here is my code

$(document).ready(function () {

After();

});

function After() {

var template = kendo.template('<li data-icon="share" onclick="After();"><a href="#:url#" data-transition="none"><span></span>#:name#</a></li>');

var data = [

{ url: '#about', name: 'Menu' },

{ url: '#about', name: 'Customer' },

{ url: '#about', name: 'Generate again'}];

var result = kendo.render(template, data);

//alert(result);

$("#ResultDiv2").append(result);

}

you can check that on the following website

Using Knockout templates in Kendo UI Mobile Control Templates

We've got quite a significant investment in Knockout templates and I'm wondering if anyone had figured out a way to be able to use Knockout templates in place of the regular Kendo templates? I know we can re-do them, but we want to re-use if at all possible, and would like to be able to stick with knockout for elsewhere in the UI.

In case no-one has any solid experience on this, whacky ideas would also be gratefully received - we're willing to experiment.

Series in columns of datasource

I have been reading a number of posts here and still am struggling with the proper method for binding series to the "columns" of a datasource.

The issue I am running up against is that I don't have control over the datasource (generic webservice call), but I need to be able to put it into the proper chart structure.

Assume my web service call returns the following:

rows: [
{ Dept: "Shoes", Q1: 100, Q2: 200, Q3: 220, Q4: 180 },
{ Dept: "Shirts", Q1: 140, Q2: 160, Q3: 390, Q4: 200 },
{ Dept: "Pants", Q1: 180, Q2: 190, Q3: 400, Q4: 320 },
{ Dept: "Tops", Q1: 520, Q2: 600, Q3: 425, Q4: 570 }
]

What I am looking for is to create a line chart where the each department is a category and the series is Q1 - Q4. The problem is, I don't know in advance that I will get for the "columns" (i.e Q1 - Q4). It might be a range of years from 2005 - 2013, or it may be a set of months Jan - Dec.

Is there a way to do this generically?

How to display a Table as the results of the AutoComplete

Using the template property of the AutoComplete, I would like to somehow display a table that contains the results of the json query.

Like in your standard ComboBox control. Is there an easy way to accomplish this.
