Hi, I have an index page that I'm trying to implement a simple kendo grid

I have followed the instructions closely here:

https://docs.telerik.com/aspnet-core/getting-started/getting-started

However I keep getting a problem of 'uncaught referenceerror kendo is not defined' on the client-side js

I have attached the relevant files.

Thanks in advance

Hi John,

This exception and the possible reason for it (registering the Kendo UI scripts outside the _Layout head tag) has been discussed in the following stackoverflow thread. As mentioned in the documentation (7.) for the scripts to be properly registered they need to be loaded in the head tag after jquery. Here's an exemplary _Layout head tag with the script and css files loaded from our CDN:

<head>

<meta charset="utf-8" />

<meta name="viewport" content="width=device-width, initial-scale=1.0" />

<title>@ViewData["Title"] - TelerikAspNetCoreApp2</title>

<link href="https://kendo.cdn.telerik.com/2017.3.1026/styles/kendo.common.min.css" rel="stylesheet" type="text/css" />

<link href="https://kendo.cdn.telerik.com/2017.3.1026/styles/kendo.mobile.all.min.css" rel="stylesheet" type="text/css" />

<link href="https://kendo.cdn.telerik.com/2017.3.1026/styles/kendo.flat.min.css" rel="stylesheet" type="text/css" />

<script src="https://kendo.cdn.telerik.com/2017.3.1026/js/kendo.aspnetmvc.min.js"></script>

<environment names="Development">

<link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.css" />

<link rel="stylesheet" href="~/css/site.css" />

</environment>

<environment names="Staging,Production">

<link rel="stylesheet" href="~/css/site.min.css" asp-append-version="true" />

</environment>

</head>

I hope this information is helpful and would allow you to deal with the exception. Let us know in case you are still getting it after moving the scripts within the head tag.

Thanks Ivan,

I have adjusted my file (attached)
_Layout.cshtml
_ViewImports.cshtml
Startup.cs

However I still cannot even see a simple date-picker in the index page:

Hope this is a simple fix…

The js error is:

I fixed it by adding the cdn to my body element in the _Layout.cshtml:

Hello John,

I am glad the issue is fixed. At my end registering the script files in the body was not needed, it was enough adding them to the head tag.

Thank you Ivan, it worked

I also had to add the cdn to the body in _layout.cshtml.

I am using ASP.NET Core 2.1. Telerik 2018.3.911.

I was getting the error Kendo(something) is not a function.

Hi Ivan,

Uncaught ReferenceError: kendo is not defined. The kendo.aspnetmvc.min.js script is not included.

Hi,

The kendo.aspnetmvc.min.js file is required and it is properly loaded in the Layout you posted. Attached you can find a sample runnable project with a Grid in the Index view. The client-side resources, including the kendo.aspnetmvc.min.js file, are loaded in the Layout's head tag through our CDN, similarly to the way they are loaded in your code snippet. At my end there are no exceptions.

We would suggest going through the steps listed in our Getting Started article, which demonstrates how to use UI for ASP.NET Core in a Core web application.

Hi Lisha,

I checked the linked project. The exception is thrown, because the BudgetNegotiation Index page is in the Areas folder. It uses its own _Layout file (located in Areas/BudgetNegotiation/Views/Shared). No Kendo UI client resources references have been added to this _Layout file, therefore using Kendo UI on the Index view causes the "kendo is not defined" exception. After adding the client resources to the _Layout file and removing the jquery bundle, because jQuery is already included in the references added to the head tag the exception is gone. See this screenshot, which shows the necessary modifications.

Hi,

The problem is caused by loading jQuery 3 times. jQuery should be loaded only once in the <head> tag (as mentioned in the documentation). So, to fix the issue, remove the extra jQuery scripts:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>@ViewData["Title"] - TimeDoctor</title>
    <link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.min.css" />
    <link rel="stylesheet" href="~/css/site.css" />


    <link rel="stylesheet" href="https://www.w3schools.com/w3css/4/w3.css">
