Questions on Kendo UI for jQuery Forum

I am using a kendo grid with an Generic Handler ashx .net handler in the back end. Everything works fine in Chrome/FF.

In IE10, I can make changes to the data, and everything appears to work. But if I navigate away form the page, and then back, I see the old data before my edits. Clicking the refresh button then shows the correct data with the new value I put in. No errors show up in the console.existingTasks

This is 100% reproducible: launch example, to to tasks.aspx. Change data and save. Click home link. Click tasks link, and see that stale data is there. Click refresh, and see the data you previously entered.

I have tried putting IE10 in compat. mode, that that makes it so that the entire grid does not even render.

Required field not being enforced.

I have a grid with a mode. I have defined the required field in the model as such:

WorkTypeID: { type: "number", validation: { required: true } },

If don't set a value for the at field, I am still able to save. Is there a way I can prevent the user from saving without choosing a value for this field?

Bolding bug

Hi, I'm wondering if there is a fix for a bug that I found. I looked but I wasn't able to find mention of in other threads.

To reproduce:

Type anything into a blank editor
Bold the first part
Select all and delete
Type anything

The bold button is off but all subsequent text is bold and I am unable to un-bold it.

Deleting top paragraph causing next paragraph to be .75em fontsize

I was able to reproduce this even on the demo site.
For the editor clear out the existing content.
1. Type Line 1 then hit enter
2. Type Line 2 then hit enter
3. Put cursor at the start of Line 2
4. Drag up to the beginning of line 1
5. Hit delete.

The text "Line 2" is not .75em.
Looking at the source, originally the text is two paragraphs. After deleting the line 2 text is a span with an inline style of font-size= .75em

Is there a way to not have this span tag add inline styling.

Edit Template Checkbox Setting

Hi,

I have a value that I am reading from a database as a 1 or 0 that I want to display in a list view as YES or NO and when editing as a checkbox...

I succesfully set the template to show YES or NO by using this code:
<div>#if(sup==1){#YES#}else{#NO#}#</div>

but I can not get the edit_template to show checked when sup == 1... it always displays unchecked.
Can you help with the proper syntax to read this value for a checkbox in an edit_template?

Thank you,
Andrew

Wrap content like text inside a page ?

Hello,

I've created a scrollview with some pages. Inside the first page there's something like :
<p>A very very long text which cannot be in the screen, [...]</p>

But the text does not fit in the whole screen, it looks like this :

If I disable the scrollview :

Do you have any idea how I can wrap the content of a page to fit the screen ?

Thank you in advance,

Retrieving the view model (ObservableObject) within a custom widget

Hello,

I am exploring building mvvm custom widgets. Although there is a clear example using a dataSource in the blogs, I want to bind my widget to an ObservableObject viewmodel.

My view model is simple:

var viewModel = kendo.observable({

message: {type:"info", text: "Hello World!"}

});

My custom widget shall display an information box with an icon defined by the type (info, warning, error, success) and the text message like in the resulting code below (styles not included).

<div id="myMessageBox">

<img src="./images/infoIcon.png" alt="Hello World!" /><span>Hello World!</span>

</div>

To achieve that, the body of my web page looks like this:

<body>

<div id="myMessageBox" data-role="infobox" data-type="message.type" data-text="message.text"></div>

</body>

I have some script to bind the view model to the body:

kendo.bind($("body"), viewModel);

and I have implemented my custom widget as follows:

; (function ($, undefined) {

"use strict";

var kendo = window.kendo,

ui = kendo.ui,

Widget = ui.Widget;

var InfoBox = Widget.extend({

init: function (element, options) {

var that = this;

options = options || {};

kendo.ui.Widget.fn.init.call(that, element, options);

that._infoBox();

},

options: {

name: "InfoBox",

type: "info", //warning, error, success

text: 'Default message for an information box',

infoIcon: 'http://application.travelfast.com/Production/App_Themes/App_Themes/images/icons/info/infoIcon32.gif',

warningIcon: 'http://application.travelfast.com/Production/App_Themes/App_Themes/images/icons/notice/noticeIcon32.gif',

errorIcon: 'http://application.travelfast.com/Production/App_Themes/App_Themes/images/icons/error/errorIcon32.gif',

successIcon: 'http://application.travelfast.com/Production/App_Themes/App_Themes/images/icons/success/successIcon32.gif',

autoBind: true

},

type: function (value) {

var that = this;

if (value) {

//check value is info, warning, error or success

that.options.type = value;

//that._refresh();

return;

}

else {

return that.options.type;

}

},

text: function (value) {

var that = this;

if (value) {

//check value is of type string

that.options.text = value;

//that._refresh();

return;

}

else {

return that.options.text;

}

},

_infoBox: function () {

var that = this;

that._refresh();

},

_template: '<img src="{0}" alt="#:{1}#" /><span>#:{1}#</span>',

_refresh: function() {

var that = this;

var template = kendo.template(kendo.format(that._template, that.options.infoIcon, that.options.text));

//How can I find the viewModel the body is bound to??????

//$(that.element).html(template(viewModel));

}

});

ui.plugin(InfoBox);

})(jQuery);

The issue I am facing is how can I access the viewModel the body of the page is bound to from within my custom widget?

Sorting inside group not working in Chrome

Hi,

I have a problem with KendoUI Grid when I group and sort - items are not sorted properly. Here is a demo: http://jsfiddle.net/7Dbkz/1/

If I use IE everything works as expected, but it doesn't work in Chrome. I have been told there is an issue with Chrome when it comes to Array.sort implementation (http://code.google.com/p/v8/issues/detail?id=90). Is there a workaround for this issue? If there isn't a solution, grouping is useless in Chrome.

Thanks,

Igor

How to disable draging of disabled node of tree view

I am trying to avoid drag and droping on disabled elements . My tree view definition is:

@(Html.Kendo().TreeView()

.Name("treeview")

.DragAndDrop(true)

.ExpandAll(true)

           .Events(e => e.Drag("...").DragStart("....").Drop("...").Select("..."))

....

.BindTo(....

item.Text = x.Name;

item.Id = x.Id

item.Enabled = false;

)

Events do some business logic for elements movement. I was trying to find on DragStart event any information about k-state-disabled class in e.sourceNode but I fail.
Also I was trying to found any Enabled property in data source element - also did not found anything.
Could someone help with this issue ? Where is my mistake?
