Hi

Would like to request to bind Treelist from Datatable with dynamic type

And Totreedatasocure to accomidate for dynamic datatable rather tha at row of static table.

Thank you

I don't See Telerik ASP.NET Core in My Tool Box.

Since support for cancellation token on user vote:

https://feedback.telerik.com/aspnet-core-ui/1357637-duplicate-kendo-mvc-extensions-support-for-cancellationtokens

https://feedback.telerik.com/aspnet-mvc/1357593-todatasourceresultasync-should-support-cancellation-token

was declined and is unplanned.

I would like to implement it by myself.

However most of methods used by code is private or internal, so extending current one is difficult to achieve without copying a lot of existing methods and marking them public. It would be good make them part of public api so implementing own extension to ToDataSourceResult and ToTreeDataSourceResult would be possible. Currently it is not.

Kind Regards

Marcin

Kendo dialog structure doesn’t use Aria landmarks properly for buttons  - this leads to a validation error

The pager control's select box renders role="listitem" but the parent is missing role="list"  - this leads to a validation error

Listviews will render role="list" even when empty - this leads to a validation error

Kendo grids use 2 tables (one for header and one for the data) which means that there are no role="cell" assigned to any of the headers  - this leads to a validation error

Scrollable grids are missing a tabindex="0" to allow for keyboard navigation - this leads to a validation error

 

this form doesn't have Core 2, 2.1, 3.0, 3.1 or 5 in the .Net Framework drop down. Just gonna pick 4.8 even though it doesn't apply. I am using core 5.

Hi Telerik Team

Wil younot implement the LightBox also as a a asp.net core component ? 


We think it will be usefull. of course we could also implement in window component but its not the same

We are needing an image editor control for an ASP.Net Core project.  The one in the AJAX does what we want.  Will it be coming to Core in the near future?

Hello,

I'm already using UI for ASP.NET Core, but want to use the OrgChart. I see that it's only in UI for ASP.NET AJAX. Can I get OrgChart to work in my ASP.NET core project?

I see that the Diagram component has been suggested as an alternative, but I don't think it's suitable for what I want.

 

Thank you.

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

Hi Telerik Team

We think it might be very useful an component in telerik like this one https://fengyuanchen.github.io/cropperjs/  for rotate, crop, resize, zoom and move. with a picture box like https://ashleydw.github.io/lightbox/#videos-gallery

If you implement this we will very happy

Thank you

 

 

Bug report

A DataSource defined using TagHelpers with disabled serverPaging sets default pageSize:

    <datasource type="DataSourceTagHelperType.Ajax" server-filtering="true" server-paging="false">
            <transport>
                <read url="@Url.Page("Index", "Read")" data="forgeryToken" />
            </transport>
            <schema data="Data">
                <model id="OrderID">
                    <fields>
                        <field name="ShipName" type="string"></field>
                    </fields>
                </model>              
            </schema>
     </datasource>

generates the following initialization script:

{"dataSource":{"page":1,"pageSize":20,"schema":{"model":{"id":"OrderID","fields":{"ShipName":{"type":"string"}}},"data":"Data","errors":"Errors","total":"Total"},"serverAggregates":true,"serverFiltering":true,"serverGrouping":true,"serverPaging":true,"serverSorting":true,"transport":{"read":{"url":"/?handler=Read","data":forgeryToken}},"type":(function(){if(kendo.data.transports['aspnetmvc-ajax']){return 'aspnetmvc-ajax';} else{throw new Error('The kendo.aspnetmvc.min.js script is not included.');}})()}

with default pageSIze set.
Initializing using jQuery works as expected:

       dataSource: {
            type: "aspnetmvc-ajax",
            serverPaging: false,
            serverFiltering:true,
            transport: {
                read: {
                    url: "@Url.Page("Index", "Read")",
                    data: forgeryToken
                }
            },
            schema: {
                model: {
                    id:"OrderID"
                },
                data: "Data",
                total:"Total"
            }
        }

Current behavior

The "page" and "pageSize" values are set, which results in only 20 items being displayed, even though more are returned by the "read" action.

Expected/desired behavior

The "page" and "pageSize" should not be set.

Environment

• Kendo UI version: 2021.1.330
• Browser: [all]

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 

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

We are building our product using an ASP.NET Core MVC project and are very excited to use the Kendo UI Sass Template.  We took a lot of time to integrate the Bootstrap Sass distribution into the project build process using Gulp and Node.js in Visual Studio to build and minify the Bootstrap Sass files so we have full control over the style and features included in our CSS files to maximize performance.

Part of this process was to make sure we used the same exact process used by Bootstrap to compile the Sass into the CSS so our process did not introduce bugs because the Sass was compiled and minified using different options than the Bootstrap team.

It would be greate if you could include options in the new project wizard to include the Kendo UI Sass template and the code necessary to build the CSS.  Additionally it would be ideal if your Sass  can be compiled and minified using the same options as Bootstrap so that if a team decides to combine and minify that code it will still work as expected.

A bonus would be if you allowed the template to also select to use Bootstrap Sass alongside the Kendo UI Sass so that a project like this can be setup quickly with minimal effort on the developers part.

Thanks for taking this into consideration,

Bryan

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.

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

Issue

Using any overload of ToDataSourceResult(Async) with a DataSourceRequest containing filter descriptors on an IQueryable provided by Entity Framework core 2.x, causes Entity Framework's "Query cache" to fill up for different filter values, leaking memory in the process. This is caused by using Expression.Constant in the generated expression trees for a DataSourceRequest's FilterDescriptors. Refer to https://github.com/dotnet/efcore/issues/14859 for more details about why this leaks memory.

Since Entity Framework's cache is always missed for new filter values, performance is also degraded due to this issue.

The issue is not present when using Entity Framework core 3 or greater. Apparently using Expression.Constant is not an issue on these version.

I have attached a minimal working example that illustrates the memory leak.

Fix

This issue can be fixed by changing FilterDescriptorExpressionBuilder.CreateValueExpression to not return a ConstantExpression, but a MemberExpression instead. Entity Framework 2.x will correctly parameterize the MemberExpression, causing the query cache to be hit correctly for queries that only differ in parameter values. It won't parameterize ConstantExpressions. Refer to https://stackoverflow.com/a/60516780/147993 for an example of generating a MemberExpression instead of a ConstantExpression.

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

Implement Recurrence Rule Parser helper that uses the Scheduler recurrenceRule string and parses it in a usable format on the server.

There is already a similar helper for Telerik UI for ASP.NET Ajax.

especially for Grid, Tabstrip, Charts...

so autosize is standard without javascript

I'd like to request that there's an easy way CRUD to a remote datasource with the ListBox, similar to the grid & treelist.
