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?

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?

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. 

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.

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!

It would be nice to have more control over the item templates. ie, be allowed to more easily do stuff like:

• Make the item non-selectable, or only selectable by a child element.
• Make the item drag-and-droppable only via a grip element.
• Make the item template display as a block, not inline.

OData v4 now supports the IN operator as a short hand for multiple or queries (as of http://docs.oasis-open.org/odata/new-in-odata/v4.01/cn01/new-in-odata-v4.01-cn01.html#_Toc485385090 ). This could help to change code such as:

var selectedStations = $("#cmbStations").data("kendoMultiSelect").dataItems();
            var stationIds = [];
            for (var i = 0; i < selectedStations.length; i++) {
                stationIds.push({
                    field: "StationId",
                    operator: "eq",
                    value: stationId
                });
            }
            dataSource.filter({
                logic: "or",
                filters: stationIds
            });

into a much cleaner:

var selectedStations = $("#cmbStations").data("kendoMultiSelect").dataItems();
            var stationIds = [];
            for (var i = 0; i < selectedStations.length; i++) {
                stationIds.push(selectedStations[i].StationId);
            }
            dataSource.filter({
                field: "StationId",
                operator: "in",
                value: stationId
            });

I've bound the PivotGrid to a XMLA-WebService (with Mondrian as Backend).

In the Datasource I've defined the error-Function.

When PivotGrid requests Data and Mondrian runs an Exception, following XMLA is transferred:

in Result the error-Parameter contains:

As you can see, the Details are missing. This wouldn't be worse - but additional xhr is away (null) - so manually parsing the result is impossible.

It should be possible to use message details - or having access to the complete Response (but xhr is not present).

Kendo pivotgrid currently has only row and column filters. Filters and Filter area are also important. See other pivotgrid implementations - especially DevExpress ASPxPivotgrid and Excel pivot table

It would be very helpful if you could standardize the button configuration across all widgets to have the same styling and usage properties. Specifically, the KendoUploader button does not have the configuration options for spriteCssClass, icon, or imageUrl. It is possible to add a background icon via css, but in some cases a texture or other background icon may be used across the entire button, making it very difficult to apply a icon as a background to the button also.

The DataSource schema must be given a total value in order to page correctly. However, DataSource expects this value to come from a response body field. In some cases, we must work with systems that return the total value as a custom field in the response header. We need a way to read custom response header values. 

Yes, the DataSource transport uses jQuery.ajax, so we can implement a custom complete function to read the response headers from the jqXHR. However, complete fires AFTER schema.total is set so it does no good.

I see in the forums you do not support what i need - but we really need it and will have to use a different control without it.  We need the ability to have the upload control, look, feel and act like it does in "Async Mode".  But when in this mode we need it to only upload 1 or two individual files at a time.  The issue is not bandwidth it is processing power.  So the "batch" trick doesn't work - we don't need all the files at once.  We need one file at-a-time, with the easy of letting the user pick a bunch and see them all listed out.  Something like

Async{  throttleLimit: 2}  - Where throttle limit simply keeps the number of pending uploads to 2 and waits until they succceed/fail to start uploading the next and so on.
