How can I programmatically add textbox controls at run time with Asp.net core using kendo UI?
( I don't want use kendo grid )
Not sure what you really want(your post strongly lacks of information), but I think you might try templates:

display: block
}
</style>
</head>
<body>
<div id="fields-container"></div>
<button>Add textbox</button>
<script>
let getValues = function getValues() {
return {
Name: "User[" + $('input').length + "]",
Value: "John Doe"
};
};
$('button').on('click', function() {
let template = kendo.template($('#textbox-template').html()),
dataValue = getValues(),
templateValue = template(dataValue);
$('#fields-container').append(templateValue);
});
</script>
</body>
</html>
Demo
As you said you don't want to use grid, I imagine that you want something like kendo does in grid that is to use templates in background. You can use a template alone without any widget at all. With the snippet above you can request data form server with ajax(in the getValues() function precisely) or grab the data from other sources.

I'm using Kendo DataBound event to print the model from the row triggering the event, the problem I'm facing is the model is undefined when using DataBound different from using Edit event.
.Events(e => { e.DataBound(#<text>function(e) { alert(e.model); }</text>) })
The problem is that apparently e.DataBound is not handling the e argument as the Edit, Cancel, and the rest of events.
When trying with e.Edit(#<text>function(e) { alert(e.model); }</text>) the e.model object is loaded with the properties and values.
Is there a way to achieve this?
You can achieve that by using jQuery only:

let grid = $("#grid").data("kendoGrid");
$("#grid").on('click', 'tbody td', function(e) {
let $td = $(e.target),
dataItem = grid.dataItem($td.parent()),
cellContent = dataItem[$td.data('field')];
console.log($td, dataItem, cellContent);
});
});

Or by using the grid's change event. But in order to use that event you need to set your grid selectable to true:

let dataItem = this.dataItem(this.select());
console.log(dataItem);

I am trying to use kendo UI validator over a textarea using validateinput but always returns false. This Dojo contains the script.
Thanks for your help.

function validateFormHecho() {
var validator = $("#hechoForm").kendoValidator({
rules: {
controlValidate: function(input) {
switch (input.attr('id')) {
case 'txtDescripcion':
return true;
break;
}
}
}
}).data("kendoValidator");
alert(validator.validateInput($("input[id=txtDescripcion]")));
}
$(document).ready(function() {
$("#txtDescripcion").kendoEditor({
resizable: {
content: true,
toolbar: true
}
});
});
</script>
</head>
<form id="hechoForm">
<div><textarea rows="10" cols="30" id="txtDescripcion" name="txtDescripcion"></textarea></div>
<button onclick="validateFormHecho()">Click me</button>
</form>
</html>
you use <textarea rows="10" cols="30" id="txtDescripcion" name="txtDescripcion"></textarea>.
But in your alert you are searching for an input elem. Textarea is not a classic HTML input, so you have to edit this part:
alert(validator.validateInput($("input[id=txtDescripcion]")));
to
alert(validator.validateInput($("textarea[id=txtDescripcion]")));
Or use $("#txtDescripcion") as the id selector
PS: you misspelled txtDescrip t ion ;)
There simple is not input element with that id. If you search for any element with that id, you get your true: alert(validator.validateInput($("#txtDescripcion")));
I want to format numeric column value as 55,25,236.30 in grid. I created a JS function and called from column template in grid. My JS function:
function NumberFormater(Price) {
kendo.culture("en-US");
kendo.cultures.current.numberFormat.groupSize = [3,2];
return kendo.toString(Price, "##,#.00");
}
but the value is showing like 5,525,236.30. According to this link the default value for groupSize is [3]. Is it not possible to set multiple values like [3,2] like numberformat in C#?
Make sure that the NumberFormater function receives a numeric argument. Below is a test page that works.
On a side note, I am not sure there is a need to set the culture and groupSize every time you execute the function.

You need to reference all these javascript files in order for the DatePicker to work. You can use the Kendo UI Custom Download tool to find out which javascript files you need to reference and to download a custom javascript file that contains everything you need:
<script src="http://kendo.cdn.telerik.com/2015.3.1111/js/kendo.core.min.js"></script>
<script src="http://kendo.cdn.telerik.com/2015.3.1111/js/kendo.calendar.min.js"></script>
<script src="http://kendo.cdn.telerik.com/2015.3.1111/js/kendo.popup.min.js"></script>
<script src="http://kendo.cdn.telerik.com/2015.3.1111/js/kendo.datepicker.min.js"></script>
<script src="http://kendo.cdn.telerik.com/2015.3.1111/js/kendo.data.min.js"></script>
<script src="http://kendo.cdn.telerik.com/2015.3.1111/js/kendo.list.min.js"></script>
<script src="http://kendo.cdn.telerik.com/2015.3.1111/js/kendo.combobox.min.js"></script>
<script src="http://kendo.cdn.telerik.com/2015.3.1111/js/kendo.dropdownlist.min.js"></script>
<script src="http://kendo.cdn.telerik.com/2015.3.1111/js/kendo.multiselect.min.js"></script>
<script src="http://kendo.cdn.telerik.com/2015.3.1111/js/kendo.validator.min.js"></script>
<script src="http://kendo.cdn.telerik.com/2015.3.1111/js/kendo.aspnetmvc.min.js"></script>
UPDATE:
Your text-box's id is "TimeSlot", but in your script you're referring to #datepicker which doesn't even exist. Change your script to this:
<script type="text/javascript">
$(document).ready(function () {
$("#TimeSlot").kendoDatePicker();
//var datepicker = $("#TimeSlot").data("kendoDatePicker");
});
</script>
By the way, you won't need kendo.aspnetmvc.min.js if you don't want to use Kendo's Html Helpers, which is not something that I would recommend if you are using asp.net MVC. With kendo.aspnetmvc.min.js, you wouldn't even need the script, you could just replace your text-box (input tag) with this:
#(Html.Kendo().DatePicker().Name("TimeSlot"))
I am trying to integrate Polymer into my Laravel app. So I created this custom web component and when I put that into my Laravel view, I get to see only blank screen. I'm using Laravel's built in web server in-case you think it can be the issue of HTML imports.
proto-element.html
<link rel="import" href="../bower_components/polymer/polymer.html">
<polymer-element name="proto-element" noscript>
<template>
<h1>Proto element</h1>
</template>
</polymer-element>
hello.blade.php
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Laravel PHP Framework</title>
<script type="text/javascript" src="bower_components/webcomponentsjs/webcomponents.min.js"></script>
<script type="text/javascript">
function supportsImports() {
return 'import' in document.createElement('link');
}
if (supportsImports()) {
// Good to go!
} else {
// Use other libraries/require systems to load files.
}
</script>
<link rel="import" href="elements/proto-element.html">

<body>
<proto-element></proto-element>
</body>
</html>
You are using 0.5 syntax instead of 1.0 syntax in the declaration of your custom element. Here's how you would do it in 1.0.
<dom-module id="proto-element">
<template>
<h1>Proto element</h1>
</template>
<script>
Polymer({
is: "proto-element"
});
</script>
</dom-module>
