see Ticket ID: 981260

var dataSource = new kendo.data.DataSource({
      type: "odata-v4",       
  });

works correct, but if you just define parameterMap
the payload of parameters is not "odata-v4" it changes to old odata
with this:

var dataSource = new kendo.data.DataSource({
        type: "odata-v4",
        transport: {
            parameterMap: function(data)
            {
                return data;
            }
        }
});

This feels like I set dataType JSON for transport, and if I just define beforeSend in Ajax Request,
I suddenly becomes XML just by defining a overwrite function.

See DoJo

This calls the DataSource read() method 10 times, but after 10 seconds only 2 of them are resolved (and actually only 2 requests are recorded in dev tools).

This is really annoying when relying on logic in a .then() block, because it is never called in the remaining cases.

Currently there is now implementation to support Guid data types. There is a workaround to use parameter mapping but this is not working when using custom methods for read\update... methods. I am heavily using web.ai driven odata endpoints and therefore I need custom transport methods and I am not able to filter Guids because auf these limitations.

Datasource result support querying the entities with ef directly column names present in the class.There should be a way to filter the entities with lazy loading them and firing the filters on them ..like if the entity candidate contains the list of interviews the ,then the canidate.interviews should be passed in the filter and value and operator should be passed

Add full support for syncing of changes made to the HierarchicalDataSource in a TreeView and Grid. Currently, sync() does not perform the correct sequence of CRUD operations that represent the changes made to the data source or control.

When you have multiple spreadsheet components on the same HTML page, allow them to cross reference each other, similar to the existing referencing capability across multiple tabs (like worksheets) but across completely separate objects (like workbooks) - of course they would need to be on the same page.

As it stands only during a read the aggregate are fetched from the server via the dataSource. This is incomplete behavior. A grid should, if requested by the programmer,  fetch the aggregates on each update of a row in the grid. That way the aggregates will always reflect the sum(), etc.. correctly.

I want to see a sample that uses MySQL as the datasource.
Sample shoulse use views to get the data and stored procedures to update the datasource.
Stored procedures exists already in the DB no ORM procedures creation needed.

In MDX you can sort the data you query for using the order function, specifying a set, a value to sort by (most commonly a measure) and the direction and whether to break hierarchy or not. I appreciate that hierarchy-breaking sorting might be quite difficult to pull off nicely, but I believe the MDX could be generated in such a way to support sorting, by specifying one of the members on an axis and the measure.

Bug report

The dataSource filter configuration only accepts string as value.

Reproduction of the problem

  1. Open the Dojo example - https://dojo.telerik.com/@martin.tabakov@progress.com/uVAgAYem
  2. Open the MultiSelect.

Current behavior

An error is thrown and the MultiSelect does not open.

Expected/desired behavior

There should be no error and the MultiSelect should open.

Environment

  • Kendo UI version: 2021.2.511
  • Browser: [all]

At the moment, the DataSource only uses one field for its ID property (if you enter several, then only one is used, apparently).  This doesn't reflect reality, in that in many cases (where one record is a child of another), the key field for a database table is a composite (from 2 or more fields).  
The existing situation causes problems in inline editing of the KendoUI grid, because default values need to be set for foreign key fields, but if these are set to a valid value, then spurious calls to the Inline_Create method occur because the DataSource treats the record as a new record when it is not.
In any case, allowing multiple fields would simply reflect reality.

"Currently the custom offline storage does not support asynchronous requests". I received this response from Kendo support is response to an issue we have using SQLite for on offline storage. When we try this with local storage or session storage, dataSource.fetch().then() resolves correctly Please implement with SQLite.

JSON data sources should be nested rather than having to define and parse flat data structures.

When using serverFiltering=true on a listview, if you type quickly 'abcd' the datasource.read is fired 4 consecutive times, making 4 consecutive server requests. There is no cap. 'abcd' can be typed within even 1 second, that will result in 4 server request per second. Now imagine 20 users at the same time typing to filter and each keystroke firing a server request is kind of an unnecessary overload.

One of key areas for enterprises is data security. If we can add the capability of encrypting data via kendo datasource, it would be awesome. 
This encryption should automatically happen when data is received from a service using the encryption algorithm specified as an attribute of kendo datasource. Similarly, decryption should also happen when the datasource receives the encrypted data.

Send filters even when the server filtering is disabled

As its documented on serverFiltering , data parameter contains filter property which follows this schema:

filter[logic]: and
filter[filters][0][field]: name
filter[filters][0][operator]: startswith
filter[filters][0][value]: Jane

When I set serverFiltering to false, data parameter doesn't contain any information about current filter. (See image attached in my first post)

And the only way I have to send the filter option in a different format is querying the DOM input element .

Shouldn't it work the same way? no matter whether filtering is set either client-side or server-side?

Currently we can only have the CRUD Operations on the remote data source. Atleast thats what it looks like. 

Is it possible to have more custom operations on Data source that can make remote calls. Or maybe there are and I am not aware of it.
