When the grid is configured for working with UTC on the server-side, the value sent from the filter menu on the client-side would not be properly sent to the server. 

If the stringifyDates option of the transport of the data source is set, the value would still be sent in a localized date format without information for the time zone, for instance, GMT(+0300).

In case the value sent from the client is modified, the parameterMap would be called afterward and would override the modified value. 

Moreover, the Kendo UI Binder on the server-side is not configured to be working with dates that have additional data for the time zone appended to the end. Therefore, sending the modified data would not be parsed correctly and FormatException error would be thrown.

This is more of a feature request...

If I want to refresh a datasource every 60 seconds, be it a grid, a dropdown, etc., I have to add a snippet of code something like this:

var interval = 60000;

         setInterval(function()

         {
             $("#my-grid").data("kendoGrid").dataSource.read();
         }, interval);

Yes, I realize this is trivial, but it would be nice if you could add an AutoRefresh function directly to the DataSource API that handled all of this under the covers.  Example:

           .DataSource(dataSource => dataSource
               .WebApi()
               .PageSize(20)
               .Model(model =>
               {
                   model.Id(m => m.StoreId);
               })
               .Read(read => read.Url(Url.HttpRouteUrl("GetData", null)).Data("additionalData"))
               .AutoRefresh(60) // seconds
               .Events(e => e.Error("onError"))
           )

http://odata.github.io/WebApi/#04-26-InOperator

 

OData v4 now supports the IN operator as a short hand for multiple or queries (as of http://docs.oasis-open.org/odata/new-in-odata/v4.01/cn01/new-in-odata-v4.01-cn01.html#_Toc485385090 ). This could help to change code such as:


var selectedStations = $("#cmbStations").data("kendoMultiSelect").dataItems();
            var stationIds = [];
            for (var i = 0; i < selectedStations.length; i++) {
                stationIds.push({
                    field: "StationId",
                    operator: "eq",
                    value: stationId
                });
            }
            dataSource.filter({
                logic: "or",
                filters: stationIds
            });

into a much cleaner:


var selectedStations = $("#cmbStations").data("kendoMultiSelect").dataItems();
            var stationIds = [];
            for (var i = 0; i < selectedStations.length; i++) {
                stationIds.push(selectedStations[i].StationId);
            }
            dataSource.filter({
                field: "StationId",
                operator: "in",
                value: stationId
            });

The DataSource schema must be given a total value in order to page correctly. However, DataSource expects this value to come from a response body field. In some cases, we must work with systems that return the total value as a custom field in the response header. We need a way to read custom response header values. 

Yes, the DataSource transport uses jQuery.ajax, so we can implement a custom complete function to read the response headers from the jqXHR. However, complete fires AFTER schema.total is set so it does no good.

I'm using Kendo UI with Vue wrappers. I have a grid that feeds from a remote datasource, but I have a custom implementation for the data service (using Axios). Currently, Kendo requires me to do this:
```
          <kendo-datasource ref="datasource" :data="rowData"></kendo-datasource>
          <kendo-grid :data-source-ref="'datasource'">
            <kendo-grid-column v-for="columnDef in columnDefs" :key="columnDef.field"
              :field="columnDef.field"
              :title="columnDef.headerName">
            </kendo-grid-column>
          </kendo-grid>
```

It seems like extra boiler plate to require the separate <kendo-datasource> tag. Why can't I bind my `rowData` directly to the kendo-grid?

We use the new version of SignalR which is 2.2.3 currently and it seems the Kendo DataSource cannot bind to it. It would be awesome if Kendo supported it. 
Here is a link: https://www.nuget.org/packages/Microsoft.AspNet.SignalR.Core/

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.

Make spreadsheet support virtual scrolling as the grid does in this example - https://demos.telerik.com/kendo-ui/grid/virtualization-remote-data

This allows handling of much larger datasets than other methods of data binding.

IMHO it would be good to separate the DTOs and the serializer/deserializer into separate assembly packages and document the protocols used to communicate with telerik components as developers may create multi layered applications without having to deploy the full telerik package eg. in business logic layers or data access layers

Please consider adding support for the new improved Signalr core to be used as an async data source and or server side rpc which would allow for greater mvvm spa applications

Although that the ListBox is similar to the MultiSelect, at the moment it does not have such model binding, because it is also comparable with the data management widgets and for the initial release of the ListBox our developers decided to consider the model binding only if there is demand for it. With that in mind, you could create a feature request in our public portal for that feature:

"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.

The DataSource API currently includes the methods pushCreate, pushDestroy, and pushUpdate.  These methods roughly correspond to add, remove, and set.  Unfortunately there is no pushInsert to enable adding new items to the data source at a specific position.  Adding such a method would be consistent with the existing add/remove/insert methods.

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

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?
