[Solved] 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?

rowTemplate, columnTemplates and flexible columns

We've been working on protoyping an application and would like to allow the user to have maximum flexibility to hide/unhide columns and perhaps reorder columns. I'm going to call this column manipulation.

We started out by using columnTemplates to format columns and column manipulation presented no issue.

However, we also want to be able to mark the entire row of the grid (i.e. when the item the row represents becomes "used") by assigning the whole row a CSS class or style (e.g. "opacity:0.30"), so we switched to a row template so that we could create the <tr> element and set its class according to a data value. We also created an alternate row template that differs only by adding the k-alt class. Works well.

However, if we allow the column menu to manipulate the list of columns, the rowTemplate (coded to expect a particular list of columns in a certain order) has a bit of an issue.

Do you have a suggestion for how to handle the whole-row decoration without using a row Template, or how to write a rowTemplate that is aware of the column manipulation?

In a somewhat related vein, is there an easy way for a columnTemplate to know what column it has been summoned forth to format? Say I want to use the same exact template for 2 (or more) columns. However, the columnTemplate is passed the entire model, not just the column to be formatted. No problem for a columnTemplate that only handles one column, but an issue for one that doesn't know which of the columns it should format data from.

The Grid will not load

Hi,

I am using MVC4 with Entity Framework 5 and I have the following piece of code that I got using samples posted on your website. Apparently, the Grid does not load at all. Am I missing something here?

I do want to mention that the Admin controller is in an "Admin" Area and I have routed requests to the Admin section correctly. Also the UnitOfWork object returns an IEnumerable object which I transpose to Kendo's DataSourceRequest. Currently, this function returns two objects in my test cases and I can see that when I go directly to the url that is bound to the read portion of the dataSource object.

Below is the Controller code.

Imports PropertyCentral.Domain.Entities

Imports PropertyCentral.Domain.Interfaces

Imports PropertyCentral.Domain.Repositories

Imports Kendo.Mvc.UI

Imports Kendo.Mvc.Extensions

Namespace Admin.Controllers

'<Authorize(Roles:="Administrator")>

Public Class UsersController

Inherits System.Web.Mvc.Controller

Private _uow As IUnitOfWork

Public Sub New(uow As IUnitOfWork)

If uow Is Nothing Then

Throw New ArgumentNullException("uow")

End If

_uow = uow

End Sub

'

' GET: /Admin/Users

Function Index() As ActionResult

Dim users = _uow.Users.SelectAll().AsEnumerable()

Return View("~/Areas/Admin/Views/Users/Index.vbhtml", users)

End Function

'

' GET: /Admin/Users/Users_Read

Function Users_Read(<DataSourceRequest()> request As DataSourceRequest) As ActionResult

Dim users = _uow.Users.SelectAll().AsEnumerable()

Return Json(users.ToDataSourceResult(request), JsonRequestBehavior.AllowGet)

End Function

End

Class

End Namespace

Here is the View:

@ModelType System.Collections.Generic.IEnumerable(Of PropertyCentral.Domain.Entities.User)

@Code

ViewData("Title") = "Administration/Users"

Layout = "~/Views/Shared/_Layout.vbhtml"

End Code

<div class="widget-box">

<div class="widget-title">

<span class="icon">

<i class="icon-th"></i>

</span>

<h5>Users</h5>

</div>

<div class="widget-content nopadding">

@*<div id="userGrid" style="height:380px;"></div> *@

@Code

Html.Kendo.Grid(Of PropertyCentral.Domain.Entities.User)(Model) _

.Name("UserGrid") _

.Columns(Sub(column)

column.Bound(Function(u) u.UserID)

column.Bound(Function(u) u.UserName)

column.Bound(Function(u) u.FirstName)

column.Bound(Function(u) u.LastName)

column.Bound(Function(u) u.EmailAddress)

column.Bound(Function(u) u.PhoneNumber)

End Sub) _

.DataSource(Sub(dataSource)

dataSource _

.Ajax() _

.Read(Sub(read)

read.Action("Users_Read", "Users", New With {.Area = "Admin"})

End Sub)

End Code

</div>

Could you please tell me why the Grid won't load the data?

Thanks,
Akshay

Editing an element on a sorted/filtered kendodatasource

Hi all, it seems that there is a weird bug when trying to edit an element on a sorted/filtered data source, both the element that will be in the previous position of the edited element and the edited element by itself in the new position gets updated with the new values.

I found that clearing the filter first and then resorting/refiltering will solve it.

datasource.filter([]);

var c = datasource.get(id);

c.set("Property", "New Value");

datasource.filter([{

field: "Property",

operator: "==",

value: "New Value"
