Kendo DataBound e.model object VS Edit e.model object - kendo-ui

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);
});
});
</script>

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

How to restrict the user not to enter characters in the summernote textarea?

e.target.blur();

Validator textarea does not work and always returns false

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.

}
}
}
}).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")));

textbox controls at run time Asp.net core using kendo UI

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:
<!DOCTYPE html>

<script id="textbox-template" type="text/x-kendo-template">
<input type="text" name="#= data.Name #" value="#= data.Value #">
</script>
<style type="text/css">
#fields-container input {
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.
