Bug report

The Kendo UI Grid's pager for UI for ASP.NET Core does not have an "All" option and it can't be configured in the Razor syntax.

Current behavior

Using the Kendo UI Grid's pageable.PageSizes, the ALL option is not available for UI for ASP.NET Core as it's only an Int32[].

Expected/desired behavior

The All option should be included like in the UI for ASP.NET MVC Razor Syntax.

I have upgraded from 2020.1.406 to 2020.2.617

after them it is not in the correct way possible for me to hidde or display the correct columns.



If i click the first or second column nothing happend..

it works again, but i'm not sure what will not be working in our WebApp if i do so.

Bug report

The Kendo UI Sortable for ASP.NET Core assumes that all selectors are by "id".

Reproduction of the problem

1. Set the .For() option of the Sortable widget to a class selector:

    .For(".k-grid table")
    // . . . 

2. Inspect the page source.

3. The following string is rendered:

    kendo.syncReady(function () { jQuery("\\.k-grid table").kendoSortable(// options) });

Expected/desired behavior

The Sortable widget should allow for passing any jQuery selectors.

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!
