Bug report

An error occurs on components' initialization when using a custom Kendo UI build which includes PDFviewer

Reproduction of the problem

  1. Go to Kendo UI Custom Download page
  2. In the "WEB" section select random components including the Grid and PDFviewer
  3. Download the custom build(kendo.custom.min.js file) and put it in the same folder with an HTML file with the following structure.
<!DOCTYPE html>

        html {
            font-size: 14px;
            font-family: Arial, Helvetica, sans-serif;
    <link rel="stylesheet" href="" />

    <script src=""></script>
    <script src="./kendo.custom.min.js"></script>

    <div id="example">
        <div id="grid"></div>
            $(document).ready(function () {
                    dataSource: {
                        type: "odata",
                        transport: {
                            read: ""
                        pageSize: 20
                    height: 550,
                    groupable: true,
                    sortable: true,
                    pageable: {
                        refresh: true,
                        pageSizes: true,
                        buttonCount: 5
                    columns: [{
                        template: "<div class='customer-name'>#: ContactName #</div>",
                        field: "ContactName",
                        title: "Contact Name",
                        width: 240
                    }, {
                        field: "ContactTitle",
                        title: "Contact Title"
                    }, {
                        field: "CompanyName",
                        title: "Company Name"
                    }, {
                        field: "Country",
                        width: 150
  1. The following error appears:
    Uncaught TypeError: Cannot read property 'Toolbar' of undefined

Current behavior


Expected/desired behavior

A Grid should be initialized properly and without errors if a custom build is including the PDFviewer

Dear Telerik,

Please check this example. The single difference than the original one from the demos section, is that I deleted the tasksDataSource.schema.model.fields.parentId.defaultValue". Now the default value of the parentId will be 0 instead of null. If you try to add a new task, the logic will break because of inifinity loop caused by the new task with id=0 and parent=the same task(parentId=0).

I checked the documentation at and this obligation is missing. It is something small that can save an hour to someone else. 

Best Regards, Boyan.

In the Wizard to create or update an MVC project, and possibly other wizards, please add support for choosing which cultures that you want to include. 


This could be done by adding checkboxes in a tree where you could at first level choose language and then expand and choose country/region, since the files follow the format:

<language code>-<country/region code>. 

Most people probably only use English and/or their native language, so please make this a choice in the wizard.

As an example. In one of the latest versions of the framework, the folders for cultures and messages contain 1786 files in total. Out of those we only need 2, the ones for our native language. 

Slowly installing and then manually deleting 1784 files in Visual Studio for every time you run the MVC wizards, is a complete waste of time for such a common scenario where you know whihc languages that the app should support.

1. Navigate to: (open the dojo sample in edit mode, but not in FullScreen)

2. Scroll Grid to the last item.

3. Open for editing ProductName cell.

4. Open for editing Discontinued cell.

Result: 'Discontinued' cell of the second item will be opened for editing.

Expected: 'Discontinued' cell of the last item should be opened for editing.

We want to copy & paste cell velue/text from kendo grid. But we are not able to select the cell text itself for copy. I think once we are able to select the cell text, we can copy than.

When a ContextMenu is opened for the first time, the animation is not executed. Every consequent open trigger the animation successfully.

The issue can be observed in the following Dojo.

Steps to reproduce:

  • Open the ContextMenu and notice there is no animation.
  • Open the ContextMenu again and notice the default animation is triggered.

Last Updated: 02 Apr 2019 13:20 by ADMIN

When showOn assumes its default value(to work with hold event on touch devices), the ContextMenu cannot be displayed by tapping and holding over the target elements.

The iсsue can be reproduced with the ContextMenu Demo.

Look at the emerging WASM projects such as Blazor or Ooui.  The obvious path seems to be to have a strong HTML based suite, i.e Kendo, ported to Blazor.  However another option would be to improve the Xamarin forms components to have comparable functionality to their desktop counterpartys so they can be used in LOB applications under Ooui.  The current Xamarin components are too mobile centric.  A third option, which admittedly seems like a bit of a long shot at present, would be to take Moonlight, strip out the plugin stuff, strip out all but the layout code, and redo that to write to an HTML Canvas.  Now that's probably outside your scope although in my opinion its the most attractive of the 3 options.  In summary I suggest you look at providing a full featured UI component suite that runs under wasm.

Create a sample Export to PDF for multiple grids.  You have sample code for multiple Grids to Excel, but not PDF.  You have a nice sample of exporting two kendo charts and a grid, but I need to export a DIV with some panels/etc, then also about 4 grids.  Similar to your example, but not sure about the jquery/Draw/Progress/Deferred code.  Thanks

A TreeView in ComboBox would be most helpful as both a stand-alone control and when editing within the Grid.

 something like this: (example from .NET Windows forms world)

* Used for relative small tree data structure.
* User may select one (many) item(s), without _loosing context_ (no interrupting dialog box, 'flat' interface).
* User may accept selection by click on item, or pressing 'enter'.
* User may cancel (hide) popup when click outside control/popup (ie in another control, that received focus) or pressing escape - like in combobox/dropdown.
* It will be nice if user can select items using keyboard arrows.
* After opening popup or selecting item, widget still has focus
* When user types in combo (with open popup), data should be filtered.
* No additional 'ok' or 'cancel' buttons to accept/dismiss selection.

We've adopted React+Redux and currently building our own component library.  Is there an official statement regarding React.js integration and roadmap?

This is a great framework that takes the best ideas of angular and react without being as difficult to learn as either of them.  Please consider it.

In order to visualize process workflow items and their sequence, a new Kendo UI control would be a big step forward. I was getting inspired by SAPUI5 control "process flow". Here the link:

This UI is able to be used in different situations:
1. Visual display of workflow steps
2. Display of relations between business work items:
connections and their frequency of usages between business workflow items .

The UI should be able to define workflow items and their connection.
It should also be possible to define templates for connection types and process item types.

Cool Kendo UI Q1 2016 webinar today... could not ask any questions using IE11 so lost on prize chances.  Very entertaining Thank you.

Are there any good working examples of using the new Grid or Spreadsheet features utilizing an API such as government information as discussed?
