css styling for grid columns; max-width for grid columns

For the Grid, is there a way to style width in css instead of with the component's "width" property in html or js?

Also, I couldn't see a solution for using css max-width to specify column widths which is what I most want to do. Is there a way to do that for Kendo grid as I can for regular html tables? The goal is to make a column take up no more room than it needs (for its widest value or its header, whichever is greater), and no more than the prescribed maximum regardless. Without max-width, it's hard to style tables well in my applications.

Thanks,

Larry

Grid's Virtualization and Grouping Support

We are evaluating the Telerik KendoUI Web Framework and want to identify it's potential. Therefore we put some effort in developing a small web application containing a Grid widget. The Grid's DataSource is based on a remote JSON source which contains about 5000 data objects.
We wanted to make heavy use of the filter, sorting, grouping and/or paging functionality because these are features which are often required by our customers.

Basically we are satisfied with the KendoUI Web Framework. Although we miss some great features we know from other Telerik products (like the Silverlight RadControls) we are happy with it's spectrum of functionality. But the greatest downside (from our point of view) is the Grid's lack of support for virtualization used together with grouping. We were not able to find a good solution to make the Grid highly responsive and user friendly while supporting large sets of data.
In our case the filtering works like charm when the virtualization is enabled. But when it comes to grouping there is this strange effect for collapsed groups: the groups are not arranged one below the other. The user has to scroll/page through large empty areas before the next group appears. This is very unpleasant to use.
When the virtualization is disabled, the filtering is much slower (but filters in an acceptable amount of time). Also the interaction on rows has a very high delay (like selection or activating and collapsing groups).

Do you have any tips regarding the grouping?
Are there plans to work on those issues in future releases of KendoUI?

EDIT: I'm referring to and voted for this feedback.

Ajax navigation with ability to link directly to the url of any page. Possible?

Hi there,

I am looking into feasibility to create mobile(phone) version of high traffic site with Kendo UI Mobile.

Following this article http://docs.kendoui.com/getting-started/using-kendo-with/aspnet-mvc/helpers/mobileapplication/overview I was able to create an example navigating pages with ajax. Since the controller is returning PartialView for the page, when you reload the url for the second page, that page seems broken as it doesn't load layout.

I was able to workaround that with this code
            if (Request.IsAjaxRequest())
                            return PartialView();
             return View();

But when I load that second page directly, link to the third page got messed up (showing the route data and appending relative url)
Everything works well though when I set PushState to false, but in that case # is added to the url.

Is my approach wrong, or there is different setup for ajax navigation with ability to load inside pages by typing the url?

Any help would be appreciated.

Thanks.

Custom tooltip.template date format based on categoryAxis baseUnit

If anybody else is wondering, because this code took me forever to figure out, here's how I change the tooltip template date format. Only works with dates, not times. Probably won't be perfect if your time zones are too far apart, but Daylight Saving Time won't screw it up.

$('#DateChart').kendoChart({

...

categoryAxis: {

baseUnit: "fit",

autoBaseUnitSteps: {

seconds: [],

minutes: [],

hours: [],

days: [1],

weeks: [1],

months: [1,3],

years: [1]

},

maxDateGroups: MaxBars,

},

tooltip: {

visible: true,

template: $('#DateChartTemplate').html()

}

});

<script id="DateChartTemplate" type="text/x-kendo-template">

# var BaseUnit = $('\#DateChart').data("kendoChart").options.categoryAxis.baseUnit;

var FirstDate = array[0].Date;

var LastDate = array[array.length - 1].Date;

if (BaseUnit == "days" || (BaseUnit == "fit" &&

Math.round((LastDate - FirstDate) / 86400000) < MaxBars)) { #

#:value#<br />

#=kendo.format("{0:ddd MMM d}", category)#

# } else if (BaseUnit == "weeks" || (BaseUnit == "fit" &&

(Math.round((LastDate - FirstDate) / 86400000)

+ FirstDate.getDay() - LastDate.getDay()) / 7 < MaxBars)) { #

#:value#<br />

#=kendo.format("{0:'Week of' MMM d}", category)#

# } else if (BaseUnit == "months" || (BaseUnit == "fit" &&

(LastDate.getFullYear() - FirstDate.getFullYear()) * 12

+ LastDate.getMonth() - FirstDate.getMonth() < 3 * MaxBars)) { #

#:value#<br />

#=kendo.format("{0:MMMM yyyy}", category)#

# } else { #

#:value#<br />

#=kendo.format("{0:yyyy}", category)#

# } #

</script>

postpone view initializations?

lets say you have something like:

<div id="tabstrip-location"
data-role="view"
data-init="app.locationService.initLocation"...

does that initialization function get called right after the app loads? as opposed to when the view is actually displayed?

is there a simple way to call initialization functions after another event has first occurred? say, after the user logs in?

Controlling styles of charts - Bevel vs. Flat

Hey guys,

I'm looking at the Kendo.All.js file to try and figure out how your Flat theme stops the charts from showing a bevel. Your theme builder is quite rudimentary in terms of what it allows you to theme unless I'm missing something. It doesn't for example allow you to specify something like bevels or no bevels.

So right now I'm going through the JS file step for step, which is time consuming and costly. How can we register a proper, complete, theme and control things like the bevels, as well as EVERYTHING else the chart may make use of? Right now the bevel is the most annoying part, but the rest would be nice too.

Thanks,
Jacques

HTML Select element bound with MVVM not behaving as expected

I have attached a sample project with a single index.html page (and supporting kendo resources). The source of that page is included below for those that don't want to download the attached .zip.

<!DOCTYPE html>

<html>

<head>

<title></title>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<meta name="msapplication-tap-highlight" content="no" />

<link href="styles/kendo.common.min.css" rel="stylesheet" />

<link href="styles/kendo.default.min.css" rel="stylesheet" />

<link href="styles/kendo.mobile.all.min.css" rel="stylesheet" />

<script src="http://code.jquery.com/jquery-1.10.2.js"></script>

<script src="js/kendo.all.js"></script>

</head>

<body id="body">

<div data-role="layout" data-id="default">

<div data-role="header">

<div data-role="navbar">

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

</div>

<div data-role="view" data-title="Select Test" data-model="myViewModel" data-layout="default" id="roster">

<table>

<tr>

<td>Selected Person: <span data-bind="text: selectedPerson"></span>

</tr>

<tr>

<!--<td><label> DataSource Select <select data-value-field="id" data-text-field="name" data-bind="source: dsPeople, value: selectedPerson"></select></label></td>-->

<td>

<label> Array Select

<select data-bound="onBind" data-option-label="Select an item" data-value-field="id" data-text-field="name" data-bind="source: arrPeople, value: selectedPerson, events: { bound: onBind}" data-value-primitive="true">

<option value="-1">Select an item</option>

</select>

</label>

</td>

</tr>

</table>

</div>

<script>

var myViewModel = kendo.observable({

dsPeople: new kendo.data.DataSource({

data: [],

schema: {

model: {

id: "id"

}

}),

arrPeople: [],

init: function()

{

for (var i = 0; i < 5; i++) {

var person = {

name: "Person " + i,

id: i

};

this.dsPeople.add(person);

this.arrPeople.push(person);

}

},

onBind: function(e)

{

alert('onBind called');

},

selectedPerson: null

});

$.ready(myViewModel.init());

// Initialize a new Kendo Mobile Application

var kidcheck = new kendo.mobile.Application($(document.body), {

skin: "flat"

});

</script>

</body>

</html>

Now, I have some questions.
1: If I un-comment the Select with the "DataSource Select" label I get an error (Uncaught ReferenceError: id is not defined). Is binding a Select element to a kendo datasource not supported?
2: Neither the "Array Select"s data-option-label, nor the initial option are honored. When the viewModel's selectedPerson attribute is null, there is no way to 'prompt' the user for input. Can the select be configured to either; use a default option to prompt for input OR select the first item in the list?
3: I expected I could implement the behavior in question #2 myself, however the "bound" method is never fired so I don't have an event upon which I can act and evaluate the state of the select. The Select is configured with both the data-bound="onBind" and data-bind="... events{ bound: onBind}" and neither invokes the onBind method.
4: Is there a location where the level of support for controlling an HTML Select is documented? Most of my questions are based on the assumption that since a dropdownlist widget and an HTML Select element derive from the same thing that there would be common behavior.

Environment:
Chrome: 30.0.1599.69
Kendo: 2013.2.918 commercial
Jquery: 1.10.2

Thanks
