I am trying to get my extended Kendo Widget to work with AngularJS.
With Kendo only my extended widget works fine you will see from the code below, but with Angular it wouldn't.
This is my code:

(function ($) {
var MyMenu = window.kendo.ui.Menu.extend({
init: function (element, options) {
window.kendo.ui.Menu.fn.init.call(this, element, options);
},
options: {
name: "MyMenu",
},
extendedFunctionality: function() {
return "extended functionality";
}
});
kendo.ui.plugin(MyMenu);
alert('menu extended');
})(jQuery);
</script>
</head>
<body>
<div ng-app="app" ng-controller="MyCtrl">
<p>Telerik Menu with Angular</p>
<ul kendo-menu k-data-source="menuData" k-rebind="menuData"></ul>

<ul kendo-my-menu k-data-source="menuData" k-rebind="menuData"></ul>
</div>
<p>My extended menu with Kendo only</p>
<ul id="kendomymenu"></ul>
<script>
$("#kendomymenu").kendoMyMenu({
dataSource: [
{
text: "Item 4",
},
{
text: "Item 5",
},
{
text: "Item 6",
}
],
select: function () {
alert(this.extendedFunctionality());
},
});
angular.module("app", [ "kendo.directives" ]).controller("MyCtrl", function($scope){
$scope.menuData = [
{
text: "Item 1",
},
{
text: "Item 2",
},
{
text: "Item 3",
}
];
})
</script>
</body>
</html>
How to get it to work?
The menu is special cased by widget name and that's why its data source isn't assigned. You better create a custom directive for that:
.directive("kendoMenuDirective", function() {
return {
restrict: "A",
link: function(scope, element, attr) {
var dataSource = scope.$eval(attr.kDataSource);
$(element).kendoMyMenu({
dataSource: dataSource
});
}
};
});
Here is an updated version of your demo: http://dojo.telerik.com/#korchev/uNiDe

I am having a kendo grid where the multiple row selection is enabled. With multiple selection functionality, when users try to copy custom text like any value from the column, it enables multiple select features thus users cannot copy custom text.
Below is the sample:
https://dojo.telerik.com/#erpuneet507/ivAfoFup
The issue is, in the above example you can select text from a single cell/ or any partial text from the cell.
If you have multiple selection enabled, then your app has to handle the copy text to clipboard. In doing so, you'll need the clipboard.js library and add a Kendo ContextMenu. Handle the copy text in the ContextMenu select event. Copy Text should pop up on right click.
Try the code below in the Telerik DOJO:

{ productName: "Coffee", category: "Beverages" },
{ productName: "Ham", category: "Food" },

$("#context-menu").kendoContextMenu({

var cell = e.target;
var row = $(cell).parent()[0];
var grid = $("#grid").data("kendoGrid");
var itemId = e.item.id;
var cellText = cell.innerText;
if (itemId === 'copyText') {
new Clipboard('#copyText', {
text: function (trigger) {
return cellText;
}
});
};
}
});
});
</script>
</body>
</html>
Here's a revised version of the above. You'll no longer need the clipboard.js. This will show/pop up the text (e.g. coffee) when you right click so that you can copy the 'ffee'.

I have some code for creating a Hierarchial tree in my angular project
I'm not sure where to use this code.
So there are only two codes- one is for HTML and another is a javascript
I created an angular project using ng new command, so it generated all the files.
Can you guide me on where I can put these codes?
html code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>AngularJS Tree Demo</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.19/angular.min.js"></script>
</head>
<body ng-app ng-controller="SampleController">
<script type="text/ng-template" id="treeLevel.html">
<ul>
<li ng-repeat="item in items">
<input type="checkbox"
name="itemSelection"
ng-model="item._Selected" />
{{item.text}}
<div ng-include=" 'treeLevel.html'"
onload="items = item.children">
</div>
</li>
</ul>
</script>
<div ng-include=" 'treeLevel.html' "
onload="items = sourceItems">
</div>
<pre> {{sourceItems | json}} </pre>
</body>
</html>
and the java script is:
function SampleController($scope) {
$scope.sourceItems = [
{
text: "Item A",
children: [
{
text: "Item A-1",
children: [
{
text: "Item A-1-1"
}, {
text: "Item A-1-2"
}
]
}, {
text: "Item A-2"
}, {
text: "Item A-3"
},
]
}, {
text: "Item B",
children: [
{ text: "Item B-1" },
{ text: "Item B-2" },
{
text: "Item B-3",
children: [
{ text: "Item B-3-1" },
{ text: "Item B-3-2" },
]
}
]
}
];
}
So basically Angular works with components. A component is basically just an independent piece of the website like it could be a navbar, a sidebar a post component etc. A component has two main parts, the HTML file and the JS file and the are both linked together. So basically the first piece of code you just showed would go on the HTML and the Javascript on the JS part of the component.
Here is more information on how this works and specially on how to create an Angular component.
PS: in the TS (Typescript, a language that inherits from Javascript but with strong typing) file is where your Javascript would go.
I hope this helped, let me know if you need more info :D
I didn't know what had went wrong where i had defined the function but it still giving error.
var sampleData = [
{ id: 1, name: "name", items: ["foo", "bar"] }
];
var defaultColumns=[
{ field: "id" },
{ field: "name" },
{ field: "items", "template":kendo.template("#= showItems(items) #") }
];
$("#grid").kendoGrid({
dataSource: {data:sampleData},
columns:defaultColumns
});
function showItems(arr) {
return arr.join("</br>") ;
}
My sample code
Make sure that showItems is defined in the global JavaScript scope in your actual application. This is required for custom functions called from inside Kendo UI templates:
http://docs.telerik.com/kendo-ui/framework/templates/overview#handle-external-templates-and-expressions
var sampleData = [
{ id: 1, name: "name", items: ["foo", "bar"] }
];
var defaultColumns=[
{ field: "id" },
{ field: "name" },
{ field: "items", template: showItems }
];
$("#grid").kendoGrid({
dataSource: {data:sampleData},
columns:defaultColumns
});
function showItems(arr) {
return arr.items.join("</br>") ;
}
I was able to solve the solution by declaring the showItems in global and it perfectly fine.
function showItems(arr) {
return arr.join("</br>");
}
var sampleData = [{
id: 1,
name: "name",
items: ["foo", "bar"]
}];
var defaultColumns = [{
field: "id"
}, {
field: "name"
}, {
field: "items",
"template": kendo.template("#= showItems(items) #")
}];
$("#grid").kendoGrid({
dataSource: {
data: sampleData
},
columns: defaultColumns
});

I realize I could do this with a template, but that would require an extra html element, since you can't change the markup of the td itself. I'd like to use a function to return attributes if that is supported.
You said you don't want to use templates, but I think you were talking about column templates.
You can change the markup of the td itself by using a row template:
<script id="template" type="text/x-kendo-template">
<tr data-uid="#= uid #">
# this.columns.forEach(function(col) {
var val = data[col.field],
css,
style = ''
cClasses = '';
if (typeof col.attributes === 'function') {
css = col.attributes(data);
cClasses = css["class"];
style = css.style
}
#
<td class='#= cClasses #' style='#= style #'>
#= data[col.field] #
</td>
# }) #
</tr>
</script>
For the loop to work, you need to bind your template to the grid though:
var grid = $("#grid").kendoGrid({
columns: [{
field: "name",
title: "Name",
attributes: function (e) {
return {
"class": "table-cell",
style: e.name == "Jane Doe" ?
"background-color: red" : "background-color: green"
};
}
}, {
field: "title",
title: "Title"
}],
dataSource: [{name: "Jane Doe", title: "Dr. Dr."},
{name: "John Doe", title: "Senior Citizen"}]
}).data("kendoGrid");
var template = kendo.template($("#template").html()).bind(grid);
grid.setOptions({
rowTemplate: template
});
(demo)
As an alternative, you could also create attributes like this:
{
field: "name",
title: "Name",
attributes: {
"class": "# if(data.name === 'Jane Doe') { # red # } else { # green # } #"
}
},
This would have the advantage of not using the row template, but you'd have to use the template syntax for the logic.
(demo)
Please try with the below code snippet.

In angular kendo callback e not work
Use this
attributes: {
"ng-confirm-message": "{{this.dataItem.is_active ? \'Are you sure deactive ?\' : \'Are you sure active ?\'}}",
"confirmed-click": "vm.inlineSubmit(this.dataItem.toJSON() ,true)"
}
For Kendo-JQuery.
<div id="grid"></div>
<script>
$("#grid").kendoGrid({
columns: [{
field: "name",
headerAttributes: {
"class": "table-header-cell",
style: "text-align: right; font-size: 14px"
}
}]
});
</script>
And this Kendo-MVC
.Columns(columns =>
{
columns.Bound(c => c.ActiveReason).Title("ActiveReason").HeaderHtmlAttributes(new { #class = "table-header-cell" });
})
Some years later but ... the attributes function is not working at all for me, is not even hit, seems pretty but not working (Why is needed a manual class toggle if a functions is provided to do the work? something seems weird).
I make editable cells based on other fields values but also I needed to change the styles
1) Add the validation on field that you want to inject the css class,
//Your other fields configuration
field:"dependentField",
attributes:
{
"class": "# if(data.ImportantField!==true) { # nonEditableCellStyle # } else { # editableCellStyle # }# ",
}
//Your other fields configuration
2) Bind the grid change event and check if some important field has changes, if is the field that controls the style of other cells just call the refresh method
var _kendoGrid = $('#myGrid').data("kendoGrid");
_kendoGrid.dataSource.bind("change", function (e) {
if (e.action === "itemchange") {
if (e.field === "ImportantField") {
_kendoGrid.refresh();
}
}
});
The refresh method will render your grid again, that means your functions weather is a template or an attribute function ( and again, that does not work at all for me) will run and apply the correct sytles, or classes in this case.
I am trying to implement jQuery FancyTree http://wwwendt.de/tech/fancytree/demo/ with local array data
Referred from https://code.google.com/p/fancytree/
This is the code. But it is not working, No Script Error.But Tree is empty!!!
Even i copied the jQuery, UI versions of the file they using in a demo
site. Still nothing works
<html>
<head>
<script src="jquery.js" type="text/javascript"></script>
<script src="jquery-ui.custom.js" type="text/javascript"></script>
<link href="ui.fancytree.css" rel="stylesheet" type="text/css" />
<script src="jquery.fancytree.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$("#tree").fancytree({
onActivate: function (node) {
// A DynaTreeNode object is passed to the activation handler
// Note: we also get this event, if persistence is on, and the
// age is reloaded.
alert("You activated " + node.data.title);
},
children: [ // Pass an array of nodes.
{title: "Item 1" },
{ title: "Folder 2", isFolder: true,
children: [
{ title: "Sub-item 2.1" },
{ title: "Sub-item 2.2" }
]
},
{ title: "Item 3" }
]
});
});
</script>
</head>
<body>
<div id="tree">
</div>
</body>
</html>
I have noticed that source:[] is how you initializes the tree in $("#tabTree").fancytree() initialization call, so your example would be:
<html>
<head>
<script src="jquery.js" type="text/javascript"></script>
<script src="jquery-ui.custom.js" type="text/javascript"></script>
<link href="ui.fancytree.css" rel="stylesheet" type="text/css" />
<script src="jquery.fancytree.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$("#tree").fancytree({
onActivate: function (node) {
// A DynaTreeNode object is passed to the activation handler
// Note: we also get this event, if persistence is on, and the
// age is reloaded.
alert("You activated " + node.data.title);
},
source: [ // Pass an array of nodes.
{title: "Item 1" },
{ title: "Folder 2", isFolder: true,
children: [
{ title: "Sub-item 2.1" },
{ title: "Sub-item 2.2" }
]
},
{ title: "Item 3" }
]
});
});
</script>
</head>
<body>
<div id="tree">
</div>
</body>
</html>
btw, in case you noticed it, the documentation is quite messy, as they are refactoring the code, the documentation is half what's left from dynatree and the new conventions of fancytree. So expect more weird stuff like that :-)
are the Scriptpath right?
Do you download "jquery.js, jquery-ui.custom.js, ui.fancytree.css and jquery.fancytree.js" ?
