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.

Hello ladies and gentlemen.

At call of Dialog.destroy() will not destroy the widgets inited in Dialog.element

Window destroy:

Dialog destroy:

...

destroy: function () {

    var that = this;

    that._destroy();

    Widget.fn.destroy.call(that);

    that.wrapper.remove();

    that.wrapper = that.element = $();

},

_destroy: function () {

    var that = this;

    var ns = '.' + NS;

    that.wrapper.off(ns);

    that.element.off(ns);

    that.wrapper.find(KICONCLOSE + ',' + KBUTTONGROUP + ' > ' + KBUTTON).off(ns);

    that._stopCenterOnResize();

},

...

In Dialog.detroy() will kendo.destroy() not be called.

Allow the customers to show and edit flow documents (DOCX and RTF).

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.

In the Wizard to create or update an MVC project, and possibly other wizards, please add support for choosing which cultures that you want to include. 

 

This could be done by adding checkboxes in a tree where you could at first level choose language and then expand and choose country/region, since the files follow the format:

<language code>-<country/region code>. 

Most people probably only use English and/or their native language, so please make this a choice in the wizard.

As an example. In one of the latest versions of the framework, the folders for cultures and messages contain 1786 files in total. Out of those we only need 2, the ones for our native language. 

Slowly installing and then manually deleting 1784 files in Visual Studio for every time you run the MVC wizards, is a complete waste of time for such a common scenario where you know whihc languages that the app should support. 

 

 

 

 

 

 

Dear Telerik,

Please check this example. The single difference than the original one from the demos section, is that I deleted the tasksDataSource.schema.model.fields.parentId.defaultValue". Now the default value of the parentId will be 0 instead of null. If you try to add a new task, the logic will break because of inifinity loop caused by the new task with id=0 and parent=the same task(parentId=0).

I checked the documentation at https://docs.telerik.com/kendo-ui/api/javascript/data/ganttdatasource/configuration/schema and this obligation is missing. It is something small that can save an hour to someone else. 

Best Regards, Boyan.

Does Kendo.Ooxml.Workbook have a setter for which sheet opens after the workbook is saved as an excel, similar to activeSheet in Kendo.spreadsheet?

(Note: using Kendo MVC ver 2017.3.913.545 - it's not on the list below)

https://demos.telerik.com/aspnet-mvc/spreadsheet/server-side-import-export

Saving large data to xlsx takes longer time to complete.

Evaluate optimizing the value setting and the usage of CellSelection.

Video: https://www.youtube.com/watch?v=8pnFjgzdaJ8&feature=youtu.be

1. Navigate to: https://dojo.telerik.com/@milena/uZaGuZol (open the dojo sample in edit mode, but not in FullScreen)

2. Scroll Grid to the last item.

3. Open for editing ProductName cell.

4. Open for editing Discontinued cell.

Result: 'Discontinued' cell of the second item will be opened for editing.

Expected: 'Discontinued' cell of the last item should be opened for editing.

Template for Kendo Gantt summary tasks, so they can be made to look similarly to regular tasks

The same applies for the MultiSelect and the ComboBox widgets. The current behavior could be observed in this Dojo example.

Binding the map layers to a SignalR Core datasource does not work. A runable project can be found in Ticket ID: 1401776

The basic configuration is:

<script>

    var hub = new signalR.HubConnectionBuilder().withUrl("mapsHub", { transport: signalR.HttpTransportType.LongPolling }).build();
    var hubStart = hub.start();

    console.log(hubStart);

</script>

@(Html.Kendo().Map()
        .Name("map")
        .Center(2, 21)
        .Zoom(3)
        .Layers(layers =>
        {
            layers.Add()
                .Type(MapLayerType.Tile)
                .UrlTemplate("http://#= subdomain #.tile.openstreetmap.org/#= zoom #/#= x #/#= y #.png")
                .Subdomains("a", "b", "c");
            layers.Add()
                .Type(MapLayerType.Marker)
                .DataSource(dataSource => dataSource
                    .SignalR()
                    .AutoSync(true)
                    .Transport(tr => tr
                        .Promise(handler: "hubStart")
                        .Hub("hub")
                        .Client(c => c
                            .Read("senddata")
                            )
                        .Server(s => s
                            .Read("senddata")
                        )
                    )
                );

        })
        .Markers(markers =>
        {
        })
        .Events(events => events
            .MarkerClick("onMarkerClick").MarkerCreated("onMarkerActive"))
            .Deferred()

)





When showOn assumes its default value(to work with hold event on touch devices), the ContextMenu cannot be displayed by tapping and holding over the target elements.

The iсsue can be reproduced with the ContextMenu Demo.

Bug report

When the filtering mode of the grid is set to "row" and the filter is programmatically cleared, the "Clear filter" button does not hide.

Reproduction of the problem

Set filterable: {mode: "row"}.
Filter for instance "Is null" or "Is not null".
Clear the filter - $("#grid").getKendoGrid().dataSource.filter({});
The "Clear filter" button is not hidden
sample Dojo:

https://dojo.telerik.com/AVOqifeK

If there is text in the filter's input, the button is hidden.

Expected/desired behavior

Hide the "Clear filter" button, irrespectively whether the filter has been cleared programmatically or via the UI.

Environment

Kendo UI version: 2019.1.220
jQuery version: 1.12.4
Browser: [all]

We want to copy & paste cell velue/text from kendo grid. But we are not able to select the cell text itself for copy. I think once we are able to select the cell text, we can copy than.

Hi,

FluentValidation is an excellent tool that keep us from using DataAnnotations' Validator's decorators to achieve the entity class keeps as is, a just POCO class. The pros of this lead us to those developers, like me, that focus its backend (entities) development in Database-First processes, to lose decorators applied to the entity or model view class in every change made to the Database rather than the entity class, FluentValidation give us a better control of the validation rules, separates the validation from the entity class or view model class, testing is easier than DataAnnotations and support client-side validations. As far as I know, FluentValidation injects Data Annotation under the covers.

It would be great if you consider to take advantage of the integration with this tool in your route map.

 

Thanks

He have created this dojo to illustrate our point.

https://dojo.telerik.com/@navdeep316/iKAmeDAv

We would like to be able to be able to clone options from the top options and subsequently to be able to edit any cloned (child) option. 

We are unable to figure out a way so that the child/cloned dropdowns can change state.

Is it a bug or a feature? How can we achieve our aim?

Thank you so much,

Dimitris 

In a grid with virtualization, when just normally scrolling down requests for the exact same data are often sent multiple times after each other. The reason for this is probably that the grid sends an asynchronous request for example Top 100, Skip 200 and then does not keep track of that it is still waiting for a reply for this request, before asking for the same data a short period later. 

Commonly requests for the same data is made 2 or 3 or more times after each other, causing performance problem at the server side and in many cases unnecessary calls to the database. Fixing this should lower the number of requests for data to the server considerably, maybe with a factor two or more with just normal grid operation when the user is just scrolling down to view more data in the grid.  

To demonstrate the problem, open a copy of the virtualization grid demo, for example here:

https://dojo.telerik.com/iXijoyaY

Open the Developer Tools and just observe which network requests are sent to the server. Just scroll down in any way and observe that very often the exact same request is made. A request for the same data has the same Top and Skip values in the parameters sent the server. You can see the servers reply is exactly the same JSON data multiple times after each other.

Solving this performance problem almost completely would seemingly be to in a variable just keep track of the "Latest request" sent, since the problem happens mostly just with normal scrolling in one direction with request sent after each other. So one would need to keep track of that a call for Top 100, Skip 200 has been made, and if the program wants to request the exact same data again, just wait for a reply for the first request, instead of sending a new one. (If needed, send a new request only after a specific timeout for a reply for the first one).

A more thorough solution would be to have a data structure to keep track of the Top and Skip tuples for all the calls to the server that has not yet have had a reply from the server, and not repeat those exact same calls again if still waiting for a reply for the first request.
