Our users love how pretty Kendo UI charts are. We usually visualize data for them with Pie or Bar charts, often in combination with a Kendo UI Grid.
However they almost always want the ability to export what they see in the browser to PowerPoint. One workaround might be to save the Kendo elements to an image and stick that into a PowerPoint slide. However they don't want that. They want a real PowerPoint slides with real PowerPoint charts and grids live objects like they were initially created in PowerPoint. We have managed to implement something to do that with OpenXML, but it will be a HUGE time saver if Kendo does that out of the box.

Dear Team,

Is there any plan or road map for the word cloud widget?

If you open the popup of the above components and resize the browser window with the popup still opened, the component is being resized according to the window size but the popup keeps its initial width. 

The above scenario can be observed on this link: https://dojo.telerik.com/ovOTUDeV 

Hi Telerik Team,

Great PDF export feature! It's the best I've seen.  We would like support for exporting to PDF/A for archival.  Is this possible? 

Thanks,

Brian 

The following typings are missing in @types/kendo-ui version 2019.3.0

1. kendo.data.TreeListModel has no parentIdField
2. kendo.ooxml.WorkbookSheetRow has no property "type"
3. kendo.ui.PanelBar has no dataSource
4. kendo.ui.DatePicker has no dateView (it's used in https://docs.telerik.com/kendo-ui/knowledge-base/datepicker-show-quarterly-frequency  )
5. kendo.ui.EditorEvent has no keyCode
6. kendo doesn't expose kendo.wheelDeltaY()
7. kendo.data doesn't expose "binders" (filed at https://github.com/telerik/kendo-ui-core/issues/4049 )
   

We are currently in the process of converting our site from using RadAjax controls into Kendo UI controls. We use a lot of drop downs (single select and multi select). While working with the Kendo UI controls, we saw that there were no multi select drop down controls available. There is a multi select control, however it uses a 'token' style and is not a control that we can use in our environment. There should be a multi select drop down control similar to the control used in RadAjax framework.

 Please provide keyboard shortcut & navigation to open a cell lookup list (menu) & for traversing menu items as shown below;

In Excel Alt+up or Alt+down arrow keys work for the same but in Kendo UI Jquery - spreadsheet , these keys are not working.

We would like the Kendo editor to provide more wysiwyg settings on headers in order to maintain accessibility standards for users. We need tables to default to data tables and not layout tables to meet accessibility checker standards.

When using the Kendo editor in Sitefinity, checking the "Associate cells with headers" box, nothing happens and I am not sure what steps need to be taken to associate them since that is the only setting in the table wizard that mentions headers. The only way to create headers is to go into the HTML and add them, this is not ideal for our users to have to do. This also creates an accessibility concern since all tables created default to layout tables versus data tables (in third-party accessibility checker), even when the table should be marked as a data table.

We need this MVC wysiwyg editor to fully function like it's webforms counterpart.  As newer users to Sitefinity we were encouraged/directed to use MVC as the product was transitioning to this model from webforms.  Unfortunately, not all of the tools transitioned to MVC retained all the functionality of their webform counterpart.

SNS and e-business always use this for make a comment.

It would be great to have a true Timeline control for showing events overtime on a scrollable axis.

dojo: http://dojo.telerik.com/UMuRaBax/3

Steps to reproduce:

1. Run the dojo, let the comobox list load and let it select the default item ('Oulu' in this case).

2. start typing 'Madrid' in the input field of the combobox.

3. press Tab key and observe behavior.

1. Please add zooming functionality to pdf viewer, so user can zoom in or zoom out

2. please allow us to hide toolbar buttons

We recently raised a ticket: 1424874.

We would like to request this ability to be added as a feature.

An error is thrown in the browser's console when pasting text + image from Word into the Kendo UI Editor: "Not allowed to load local resource: file:///C:/Users/..."

This is due to the inability of the browser to access the image file, located on the client machine.

The explanation of the above is the following. If you test the following sample (note, that it does not use Kendo) in Chrome, and try to paste text + image in the ​contenteditable <div>, you will observe the same error. The Editor also renders its content in an editable div element. The browser does not recognize that the user attempts to paste an image. Instead of reading the image data and loading it as a base64 string to the src attribute of the <img> element it generates an <img> tag which points to the clipboard location of the file on the client machine. As the browser is not allowed to access such resource, it trows the error observed and the image is not rendered.

To resolve this issue, when pasting only an image (no text), the Editor has its own internal implementation. Therefore, the user is able to paste images (e.g. clicking on the image in Word->Ctrl +C->then Ctrl + V in the Editor). However, when pasting it together with text, the widget does recognize the text and does not apply the custom processing aimed to convert the image. Therefore the native browser behavior of pasting images is exhibited.

Dear staff,

I am working extensively with Kendo UI Drawing API, specifically with drawDOM and exportPDF methods. I encountered a strange issue, which leads to the generation of corrupt PDF files.

After several attempts to analyze the problem, I found a small piece of code that allows to systematically reproduce the issue. You can find the code as attached.

Opening the example page with Chrome browser I got a corrupted PDF file, while Internet Explorer seems to generate a valid PDF file starting from the same source page.

Checking with an online PDF validator, the file generated by Chrome exploits this validation error:

    “The content stream contains an invalid operator.

      The operator has an invalid number of operands.”

I’m not skilled with PDF internals, but comparing the valid file of IE and the invalid file of Chrome, I noticed that an “infinite” value appears in the invalid PDF.

The row in the valid PDF is “1 0 0 -1 -9494.7900391 -9965.5996094 cm“, while the same row in the invalid PDF is “1 0 0 -1 Infinity Infinity cm”.

I noticed that the presence of an “Infinite” value is the common behavior whenever the corrupt PDF problem occurs.

Hello.

When I tried your framework, I found a lot of positive and useful components, but unfortunately in our conditions I can not fully use the components with virtualization, because they can not work without counting the number of records. I have a lot of data and any scrolling, page selection, components such as combobox, dropdownlist, pager, grid, etc., every time i have to count the total number, and the queries are complex, not just select * from. Performance drops immediately, imagine i'm scrolling through a combobox, where there are 6 million records, where on every page Iihave to do select count(*) from table .. join...join... where .... and add to that another 100 users that all scroll the same combobox, for example.  It would be great to be able to simply load data page by page without counting the total, but remove invisible elements from the DOM if the number of pages loaded is greater than a certain number.

Some other commercial frameworks have similar things.

I would not like to look for other alternatives, because you have done a very good and high-quality work. Maybe there are workarounds to this problem?

I'm not just talking about the grid, such controls combobox, dropdown do not have the functionality of endless scrolling. I'd like to see something like

https://github.com/ElemeFE/vue-infinite-scroll

And you can find out when the interface should finish scrolling by an empty response from the server, when there is no more data.

Why not just scroll through the list, adding a portion of data without a total, if the next portion is empty, then finished.

You have even the library train sewn count number when calling ToDataSourceResult on IQueryable

https://github.com/kendo-labs/dlinq-helpers/blob/master/Kendo.DynamicLinq/QueryableExtensions.cs

Counting the number of rows on complex queries is a rather expensive operation.

I would very much like to see such functionality on your widgets

 PS: I have already talked on this topic with your developers

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

Since the "workbook.columns[0].width" exists when exporting to Excel AND that the mix of cell.colSpan and cell.wrap doesn't change the row height automatically when the text wrap (it only works when colSpan = 1) I'd like the ability to change the row height manually :

rows[0].height = 50

Of course the best implementation for us would be the automatic row height calculation when text wrap with colSpan > 1.

Thank you !

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.

    </div>
</body>
</html>

4. 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

Environment

• Kendo UI version: 2019.2.514
• jQuery version: x.y
• Browser: [all]
