I was trying to use negation operator in a binding using MVVM, just like angular does it, for example I am going to use, you could say why don't use "invisible", it could work on this example, but we have some others custom bindings, or some other scenarios were we have to create multiple properties to handle that, which is a pain.
EX
<div id="example-1" data-bind="visible: !IsNotAdmin"></div>
<div id="example-1" data-bind="customBinding: !IsAdmin"></div>
So, are you supporting the negation operator on bindings or are you planning to do it?

The Kendo Grid has select() method, but is missing unselect() method. I believe that it will be a good and useful addition to the grid.

With Excel when you use a custom number format of #,##0.00 and you enter (10) into the cell it will be displayed as -10.  With the Spreadsheet control the same example yields (10).  How can we get the same behavior as Excel with the Spreadsheet control?

Hello,

I have an 8mb PDF files that I need to be able to search, however when I click on the search tool the entire page starts responding.

This issue happens in your hosted demo. It seems to come as a result of images in the PDF.

What do I need to do to have it work properly?

Thanks,

Greg

Inserting a column in between columns that have been populated from a DataSource on Spreadsheet Sheet

Hi Team

We develop under Aurelia Framework and use KendoUI components.

It would be nice if there will be an update of the "Aurelia Kendo UI Components Catalog".

By complementing components used by "Jquery components catalog" with examples for Aurelia users that uses Typescript.

Mostly it is hard to find good tutorials for Aurelia + KendoUI users.

Best regards,

Thomas 

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.

Currently when the add() method is called on a DataSource, if the id, as defined in the Model, is included, then the sync method is called, the data is not persisted to the _pristineData object, and neither the Create nor Update transports are called.  This has the effect of not persisting the data and so if the cancel button is pushed on an edit screen, the added object is mysteriously dropped.  

Please see my post on the kendo forums for a more detailed explanation including demos of the issue.  http://www.telerik.com/forums/if-id-is-provided-in-add()-sync-does-not-update-_pristinedata-and-create-update-are-not-invoked

I would suggest that anytime the add() method is used, it should be considered a 'new' record, or at least when the id provided does not match with any other id currently in the data array. If it matches a record in the data array, run the Update transport, otherwise, run the Create transport.  Simply including a value for the id should not remove the record from ever being persisted. 

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

Dear Telerik,

My problem is behind the "timelineMonth" view of the Scheduler. In the documentation it is written that "showWorkHours" has a support only behind "day" and "week" views. But it is not really like that. In fact, it is included also in "timeline" and "timelineWeek" views and it works fine. Even more, this feature works also in "timelineMonth", but with a small exception that I want to focus on your attention. 

Here is an example showing the problem. It's only about selecting the "today" (in my example the "date" property is showing "today". The same behavior could be achieved if you change it to another date and click the "today" button).

I can show you another particular example describing why this feature is very useful. Here, if the user press on "show business hours" button and then select the "Timeline Month", he will break the logic behind. And it makes somehow the "Show Business Hours" button problematic. And let say I should make some workaround to avoid this thing happens, but not sure why.

Hope this is valuable.

Best Regards, Boyan.

I'd like to have the ability for icons to be displayed in Internet Explorer even when web font downloads are disabled.

It seems the best way to support this scenario is to use inline SVG in order to support changing the icon colors.

See https://www.telerik.com/forums/is-there-a-fallback-from-webfont-icons

Thank you.

There should be a render function of some sort that can be called that changes how the Uploads are displayed.
In the attached image, I uploaded a single file, then two additional files.
Rather than having a set of one and a set of two, I'd prefer to have either a set of three, or three sets of 1. 

I understand that the plugin creates an input element for each individual uploading, however, I think there would be value in being able to join or split those files into multiple elements. It may even be beneficial to add and utilize a FileList object in the Kendo Upload object, as this would allow for the uploads to be sorted alphabetically, or by type, and so on. 

To recreate the behavior mentioned, simply upload any number of files to an Upload control and then do that one more time. The behavior can be recreated on the Telerik website demos.

Hi,

It would be great if the KendoUI Grid could be enhanced to automagically recognize when it's grouping by a date field and then offer additional options to group the dates by Day, Week, Month, Quarter, or Year.

Thank you.

Barry

Dear Telerik team.

I would love to have the possibility to use drag & drop with different browser windows. As shown here.

That way my customers could make use of their multi-monitor workplaces. Opening a grid or listview with items on one screen and opening a scheduler on the other screen. Then dragging from the grid to the scheduler.

Kind regards

Bernd

This is more of a feature request...

If I want to refresh a datasource every 60 seconds, be it a grid, a dropdown, etc., I have to add a snippet of code something like this:

var interval = 60000;

         setInterval(function()

         {
             $("#my-grid").data("kendoGrid").dataSource.read();
         }, interval);

Yes, I realize this is trivial, but it would be nice if you could add an AutoRefresh function directly to the DataSource API that handled all of this under the covers.  Example:

Hello,

The Kendo UI Window features in many widgets as an editable popup and form container - like the Kendo UI Grid and TreeList, the Kendo UI Diagram and it would be great to be able to keep using it and open it elsewhere dynamically as right now this takes no effect.:

Thank you for voting!
