I've setup a new ASP.NET Core project with Kendo UI Core. One of the requirements for this site is to load the scripts/styles from CDN except when the internet is down, in which case it should load from local files. I downloaded a copy of Kendo UI Core 2019.3.1023 and extracted it into the project. I have an ASP.NET Core Tag Helper which handles hashing the local file and using that SRI to load the CDN version.

Here's an example of that generated tag and the fallback:

<link rel="stylesheet" href="https://kendo.cdn.telerik.com/2019.3.1023/styles/kendo.common.min.css" integrity="sha384-tr4PSEV2CnVkku/o7s0ApjrlIpaxzBOMQTYc8SsPFXXh6ITUZ/SS7t8k8PVUa1Tk" crossorigin="anonymous">
<meta name="x-stylesheet-fallback-test" content="" class="k-widget"><script>!function(a,b,c,d){var e,f=document,g=f.getElementsByTagName("SCRIPT"),h=g[g.length-1].previousElementSibling,i=f.defaultView&&f.defaultView.getComputedStyle?f.defaultView.getComputedStyle(h):h.currentStyle;if(i&&i[a]!==b)for(e=0;e<c.length;e++)f.write('<link href="'+c[e]+'" '+d+"/>")}("box-sizing","content-box",["/lib/kendo-ui-core/styles/kendo.common.min.css"], "rel=\u0022stylesheet\u0022 integrity=\u0022sha384-tr4PSEV2CnVkku/o7s0ApjrlIpaxzBOMQTYc8SsPFXXh6ITUZ/SS7t8k8PVUa1Tk\u0022 crossorigin=\u0022anonymous\u0022 ");</script>

When the hash is calculated from the local file, the CDN copy does not match. So far I have only had an issue with two files: kendo.common.min.css and kendo.bootstrap-v4.min.css: both of these files have different headers from the download and CDN versions and appear to be minified differently. It would be great if future versions could be the same so that the hash for a local file matches the hash for the CDN version.

As a side note, it would be really great if you could work with Libman (the Visual Studio CDN downloader tool) to be able to download Kendo UI Core. The only version that exists currently on that system is very old.

Bug report

The workbook exporting to Excel generates a corrupted file when the name of some of its sheets contains a "cell-related" value - for example, "A1", "G5", "F45", etc.

Reproduction of the problem

1. Open this Dojo project and run it
2. Save the exported Excel file and open it.

Current behavior

When the saved file is opened in Excel, a "corrupted file" warning appears on the screen.

Expected/desired behavior

There shouldn't be any warnings when opening a saved workbook

Environment

• Kendo UI version: 2019.3.1023
• jQuery version: x.y
• Browser: [all]

Clicking an item in the parent list reveals the child list that replaces the parent list.

At the top of the child list, there is a < back item that allows returning to the parent list.

For examples, see the drawers at:

• https://www.amazon.com/
• https://www.diy.com/ (make the window small enough to display the drawer button)
  

See also https://www.telerik.com/forums/kendo-ui-drawer-subitems

Please provide support of row grouping as it is going to be a very useful feature and excel is rich data file so we always need to group various sections. An example of the feature is available in the attached file and the link below.

Bug report

When a custom class attribute is set via the columns.attributes option, the TreeList renders an additional class that is undefined.

Reproduction of the problem

1. Initialize a TreeList.

2. Set a custom class via the attributes option:

3. Inspect the relevant "td" element

Dojo sample for reproduction:

https://dojo.telerik.com/IqApoGOz

Expected/desired behavior

The TreeList should render only the specified classes.

Environment

* **Kendo UI version:** 2019.3.1023
* **jQuery version:** 1.12.4
* **Browser:** [all] 

See dojo at https://dojo.telerik.com/@GaloisGirl/akAlaDIP .

The first DateTimePicker is set as readonly and has also aria-readonly manually set to true. It is correctly read by my screen reader (NVDA).

The second DateTimePicker is only set as readonly. It is read by the screen reader editable. It is not marked as readonly in the accessibility tree (per Firefox Developer Edition 71).

I can't find a formal specification, but this page says an input with ARIA role="combobox" needs to have "aria-readonly" set in addition to "readonly".

I'm documenting this for the DateTimePicker , but the same problem occurs for ComboBox ( https://dojo.telerik.com/@GaloisGirl/egeLOxIt ) and possibly other widgets that use the ARIA role combobox.

Hi,

I'm not sure this will be a bug in your mind but I just wanted to make sure I understood how things work. We have a grid definition which includes the dataSource.schema.model definition. One of the fields (TradeDate) in the schema has a type = "date". In addition, we assign local json data to the "data" property of the dataSource. Our JSON data comes in with dates in the ISO format (a string with the "T" in it). When the grid is initially created everything works fine. We notice that the TradeDate field in the dataSource.data() is converted to an actual javascript date. I assume this is happening because of the schema definition. Later we retrieve new data via an ajax call and apply it to the grid using the grid.dataSource.data(newJson) command. However this does not seem to process the TradeDate field and convert it into a real javascript date. This causes problems because we have filters applied based on the TradeDate. It works fine the first time but fails any time the data is refreshed (because the field value is a string). We tried the schema.parse function but that also is only called the first time. Ultimately we coded the grids "dataBound" event and everything worked. It gets called each time the data is refreshed. I was just wondering if I could be doing something differently so that the schema handled the conversion all the time.

self._grid = grd$.kendoGrid({
columns: [...],
        dataSource: {
schema: {
                        model: {
                            id: "somekey",
                            fields: {
                                NewTradeFlag: { editable: false },
                                TradeDate: { editable: false, type: "date" },
...
                            }
                        }
                    },
                data: self.ViewModel.DisplayData.TransactionData
         }
...
})

Later on we do this

self._grid.dataSource.data(newJsonData);

P.S. we originally were using MVVM binding straight to the ViewModel but that didn't work either.

Thank you in advance, Jim.

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 

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.

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.

As a suggestion from the response that I've got from Ivan Danchev, I'm raising a new feature to enable/disable columns auto-resize in the the treelist of the gantt chart. Currently the columns width is "static" when it is defined in the column configuration. It'll be great if the columns are resized automatically depending on the length of content in the columns.

Thank!!!

Hi there

This is just a general question in relation to Kendo UI.  Does the Kendo UI component from the DevCraft susbcription has a wrapper for expressjs/nodejs

If not, there is any plan to add this to the library

Cheers

When using a grid with locked columns if the unlocked area is scrollable once scrolled horizontally the resize handle keeps it's original absolute positioning and doesn't respect the change in scroll. 

When hovering over the edge of the column I can no longer see the resize handle. I can hover to the left where it would have been with no scrolling and then see it. 

On DOM inspection I see the event to update the handle's position STILL FIRES when hovering the edge of a column header, but the position is based on scrollLeft() === 0. 

I will assume the needed left position for each column is calculated on creation but is not re-calculated for horizontal scroll. 

This can be reproduced in the live demos on Telerik's site.

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.
