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.

<!DOCTYPE html>
<html>

<head>
    <style>
        html {
            font-size: 14px;
            font-family: Arial, Helvetica, sans-serif;
        }
    </style>

        <div id="grid"></div>
        <script>
            $(document).ready(function () {
                $("#grid").kendoGrid({
                    dataSource: {
                        type: "odata",
                        transport: {
                            read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Customers"
                        },
                        pageSize: 20
                    },
                    height: 550,

                        field: "ContactName",
                        title: "Contact Name",
                        width: 240
                    }, {

                        width: 150
                    }]
                });
            });
        </script>
    </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]

Often, working with the Kendo events is difficult, because the events lack any kind of context. For example, the Change event should also pass back OldValue and NewValue, in case you need to do any additional comparative work on your own, without having to figure out how to get back to the DataItem and figure it out for yourself.

Also, if you are handling a Grid row changed event, or cell changed event, at the very least you should be passing the Uid of the row that changed, so I can get it from the data source. 

When a text with background color set is made bold and copy/pasted, the background color is not being preserved.

The issue can be reproduced on the following Dojo example.

Steps to reproduce:

• Type some text.
• Select the text and set a background color.
• Make the text bold.
• Copy/paste the text on a new line.

Bug report

Reproduction of the problem

Dojo example.

Current behavior

A difference between kendo.culture.ar.min.js:

pattern: ["-n %","n %"],

and other Arabic cultures, e.g. kendo.culture.ar-AE.min.js:

pattern: ["-n%","n%"],

A space is present in between the % symbol and the number and the position of the percent symbol differs.

Expected/desired behavior

Format consistency.

Environment

• Kendo UI version: 2019.2.619
• jQuery version: x.y
• Browser: [all]

Bug report

Almost all formatting tools such as fontName, fontSize, backColor, foreColor, bold, italic, etc. do not change bullets in unnumbered lists and numbers in numbered lists. Please see the sample below:

1. One (italic)
   
2. Two (bold)
   
3. Three (green)

I would like there to be a simple input field that allows a datasource to be attached. This would support update database operations to be sent as JSON to the desired URL, much like grid or gantt do.

Seems a bit of an oversite that you don't have this on, given the width and breadth of your other controls.

We reaally need to use the overlay animation, our client is driving us nuts with it. They are showing us the examples in Jquery mobile panel (http://demos.jquerymobile.com/1.3.0/docs/widgets/panels/) and asking us why we are using Kendo if we cant deliver this animations. 

Please help us voting for this animatiosn.

It would be nice to have a built in PDF viewer control in the Kendo UI and Kendo UI Mobile. Especially Mobile so we do not have to search the net for decent controls that may or may not work for the different devices.
