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.

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.

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.

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?

It would be really useful to be able to modify request parameters in the RequestStart event of the dataSource; this would be consistent with the functionality of the Kendo Tooltip RequestStart Event.

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.

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;
}

I'd like the formatted "text" property of the DatePicker widget to be bindable to a model. The DatePicker widget currently supports the value binding. 

This way the model would contain the same string value entered by a user and not a javascript date object.

For controls like ListView (web and mobile). We have features like server filtering. I feel there should be a configuration to perform filter operation mixing both client side and server side filtering. 
Scenario 1: Lets say I have 20 results to be populated based on the filter criteria and I have 2 results already present on the client side and rest 18 are present on the server rather than fetching all 20 results from server freshly this way data transfer can be optimized up to certain extent.

Scenario 2: filtering should results based on the client side results and list out 2 results and there should be option load more from server similar to outlook mail search feature.

We have a MVVM object with a change handler.

One of the public properties on this MVVM object is a datasource.

This datasource has some default aggregate configuration, but some aggregate configuration is added later. (see first screenshot)

However, when the dataSource.aggregate(..) method is called the MVVM's change handler fires (see second screenshot). This is ok, but there is nothing to distinguish that the change handler has been fired ONLY because the aggregate configuration has changed. When run some code when the datasource is defined or loaded, but we don't want to run the same code when the aggregates changes.

Vice-versa someone might want to run just a smaller piece of code when the aggregate config changes.

Can the event that gets fired to the mvvm change binding have an e.action = 'aggregate' or similar?

Currently the grid fires the change event if the user clicks on a row. I can use this event to do something, for example, update controls in a detail part of the page below the grid.

If the user groups or sorts the grid, the grid rebinds. It does fire an event for that, but since the grid also removes any selection, to be consistent, it should also fire the same event it fires when the user selects a row. After all...the selection is changing (to nothing).

kendoui data source should support working with arrays or arrays rather than arrays of objects
this way the json being passed between the client and server can be much smaller (and network times reduced)

it will require positional information in order to get to each field instead of name
it will be especially important for grids

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.

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
