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.

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

"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.

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.

Currently all "data*-template" options are limited to use ad #ID selector to pick the template script from the page.
This is problematic in big SPAs that have multiple pages dynamically loaded with possible collisions in IDs.
To avoid the hassle of mantaining unique ids across all pages (or having to dynamically generate ids) I therefore propose to allow for any jQuery selector in those options.

<script type="text/template" class="myAwesomeTemplate"></script>
<div data-bind="source: dataSource" data-template=".myAwesomeTemplate"></div>

To maintain retrocompatibility a first search with the "#" can be performed before executing the selector.

Since I am not very good with GitHub, here is the code that I did implement:

function parseOptions(element, options) {
    var result = {}, option, value, templateElement;
    for (option in options) {
        value = parseOption(element, option);
        if (value !== undefined) {
            if (templateRegExp.test(option)) {
                templateElement = null;
                if(!value) {
                    throw new Error("Missing template selector in option " + option);
                }
                try {
                    templateElement = $("#" + value);
                    if(!templateElement.length) {
                        templateElement = $(value).first();
                    }
                } catch (jQueryError) {
                    throw new Error("Invalid template selector " + value + " for option " + option);
                }
                if(!templateElement.length) {
                    throw new Error("Can't find a template with the specified " + value + " selector in option " + option);
                }
                value = kendo.template(templateElement.html());
            }
            result[option] = value;
        }
    }
    return result;
}

The filter row is really nice, but for more flexibility it'd be nice to not hit the server until a user has populated the row with all the filters they want. The way it works now is if you tab out/hit enter/select dropdown list item/etc. it hits the server. The ability to filter when the user explicitly wants to isn't really there.
