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: .

Checked on your website as well, but the issue is also coming there. Here is the URL:

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!

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.

Whenever the foreign key column of the grid is configured for multi checkbox filtering and is nullable, the value of the "null" option is sent to the server as "NaN".

Steps to replicate:

1. Set ForeignKey column

2. Make the column nullable

3. Set the filterable.multi option to true

4. filter by the null value

We're using a drop down list as a grid cell's edit template, but.. our users are unable to properly edit the rows at the bottom of the grid due to drop down list going off the page, and closing when they attempt to scroll.


any ideas?
