For computations in a custom aggregate function it would be very helpful to have the start and end DateTimes for the current category at hand.  Right now the category parameter just provides a single DateTime which is the start DateTime of the category.  The end DateTime can only be calculated with a workaround provided by Tsvetina

Hi Team

With the latest version of Kendo (Silver Theme), The selected color of a Panelbar was white now it's blackish.

Do you have a quick fix for that?

Many thanks

Hi,

We have a property EnableHeaderContextAggregateMenu in Radgrid. By enabling this, we can aggregate any column in the Radgrid and show the result value in the corresponding column footer at runtime by the end user.

Do we have similar property in Kendo UI Grid? We need to implement this in Kendo UI Grid which has dynamic column data binding. We had attached a sample code here. Can you please implement the same in the code and revert?

Thanks & Regards,
Shivakumar. K

I'm currently evaluating the ASP .Net Core Components and whilst I'm liking it so far, I have to say - the documentation leaves a lot to be desired.

At the moment, I am trying to use grid and looking at documentation, I have no idea if I am meant to be looking in Kendo.Mvc.UI.Fluent or Kendo.Mvc.UI - and when I am there and find an item, there just isn't enough detail. In addition, the demos section appears to actually be more helpful and I'm constantly looking there.

What caused me to write this is that I have simply enabled GridFilterMode.Row on an instance and whilst I like it, I want to change the default from "Is Equal To" to "Contains"... I have been experimenting for the past few hours without any luck and I'm going round in circles on documentation:

I can see that Filterable requires GridFilterMode, but the documentation is lacking - https://docs.telerik.com/aspnet-core/api/Kendo.Mvc.UI/GridFilterMode#kendomvcuigridfiltermode

I then try to find the filterable modes documentation, but, half the features/methods just don't seem to have any affect whatsoever.

Personally, I'm having great luck learning about your components from the demo section and adapting the code to suite my needs - but, if there isn't a demo, it appears to be a very hard task to learn what is and isn't possible.

Hi Kendo Team,

I am working on Kendo UI ASP.NET Core Grid binding with SignalR. But while starting Hub and providing the Promise, I am facing an error "The "promise" option must be a Promise."

I am following this URL for reference: https://demos.telerik.com/aspnet-core/grid/signalr .

Checked on your website as well, but the issue is also coming there. Here is the URL: https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/configuration/transport.signalr

In this link, when clicking on "Open In Dojo" button, it opens a new window, then clicks on the Run button. It will generate an error in the console "Uncaught Error: The "promise" option must be a Promise.". 

Please check the attached snapshot.

Please reply asap. Thanks in advance!

Hello good afternoon all right?

I am developing a code where I create a base model of a window and use javascript to be able to define data like autura, width, content (URL) and etc ...
In the example I am doing, I have a menu that according to the ID of the item that I clicked on the menu, it performs a function and according to the ID, it defines the data of the Window, as I do not have a component like "RadWindowManager" to facilitate this part of the creation, I am doing this process:

Component Code:

<nav class="navbar navbar-expand-xl navbar-light bg-light">
        <a class="navbar-brand" href="#">
            <div> <img src="~/images/selo.png" class="pull-left imagem" /> </div>
        </a>
        <a class="navbar-brand" href="#">
            <img src="~/images/softlux.png" class="logo_posicao" alt="">
        </a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>
        <div class="collapse navbar-collapse" id="navbarText">
            <ul class="navbar-nav mr-auto">
                        <li class="dropdown nav-text">
                            <a href="#" class="nav-link dropdown-toggle" id="navbarDropdownMenu" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" onclick="aoClicar('3,0')">
                                Example Window 1
                            </a>
                        </li>
                        <li class="dropdown nav-text">
                            <a href="#" class="nav-link dropdown-toggle" id="navbarDropdownMenu" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" onclick="aoClicar('6,0')">
                                Example Window 2
                            </a>
                        </li>
                        <li class="dropdown nav-text">

                                Example Window 3
                            </a>
                        </li>
            </ul>
        </div>
</nav>

Scripts Code:

<script type="text/javascript">

            switch (idItem) {
                case "3,0":
                    var janela = $("#FrmGrid").kendoWindow().data("kendoWindow");

                    janela.setOptions({
                        title: "Table of Environments",
                        width: 980,
                        height: 440
                    });

                    janela.refresh({
                        url: 'http://' + window.location.hostname + ':' + window.location.port + '/Ambiente/Index'    // Open a Controller and Action as Frame
                    });

                    janela.center().open();
                    break;
                case "6,0":

                        width: 980,
                        height: 400
                    });

                    janela.refresh({
                        url: 'http://' + window.location.hostname + ':' + window.location.port + '/Profissao/Index'    // Open a Controller and Action as Frame
                    });

                    janela.center().open();
                    break;
                case "12,0":
                    var janela = $("#FrmGrid").kendoWindow().data("kendoWindow");

                    janela.setOptions({
                        title: "Table of reasons",
                        width: 980,
                        height: 560
                    });

                    janela.refresh({
                        url: 'http://' + window.location.hostname + ':' + window.location.port + '/Motivo/Index'    // Open a Controller and Action as Frame

                    janela.center().open();

                    alertify.error('Window not disponible.');
            }
        }
</script>

However, I noticed 2 problems in Defining Options such as height, width, title, and content
If I use this method to define:

janela.setOptions({
    title: "Table of reasons",
    width: 980,
    height: 560
});

The final result of the window looks like this:

Note that the Content Frame is passing outside the window border, or in case the background shadow of it, in other browsers the size may even follow the pattern of the shadow, but in Google Chrome you get this part beyond the limit.

If I use this method to set the properties:

var janela = $("#FrmGrid").kendoWindow({
        title: "Table of reasons",
        width: 980,
        height: 560
    }).data("kendoWindow");

When you create the first window, you create it without problems:

Hi,

We have  a requirement for circled progress bar. Need to know whether you have specifications regarding the requirement or any optimization need to be done within the given framework to get the desired result. Please find the attached file for reference.

I`m working development and produced I4.0 devices as well app systems since 3 years.  Are Telerick involve in this applications. 

Even when using server side paging some requests can be very long, and may be canceled by the user.  Adding a CancellationToken parameter to the ToDataSourceResultAsync.

Provide support for the asp-page-handler attribute to call a handler in an ASP.NET Core 2.1 Razor page in addition to supporting controller/action methods.

I want to design a web page with text and signature input. In Tablet I need to enter the text fields and signature fields using touch pen. I want the web page to allow the touch pen to write comments and signature and save into database

Due to changes in the ASP.NET Core framework and how the Authentication is implemented the MVC5 implementation of the SecurityTrimming option became obsolete. 

Need support for DataTable in Grid in ASP.NET Core 2.0

Please add an option so that is possible to set Deferred rendering default setting to either true or false globally.

Currently the default is false and can only be overwritten on a control basis and not globally.

This would benefit those customers that have decided that all/most of the controls are rendered as deferred(true). Currently they have to append the Deffered(true) to each of the helpers.

Allow HTML comments & other tags to be mixed inside kendo tags; eg. I would like to use a <asp-partial name="_template" required=false asp-if="@User.IsInRole("role")> to inject settings/configuration of the kendo component 

I have a donut chart which represent as a circle and in middle of cricle there is some text, which needs to drilldown, hence click event need which is very necessary
