This feature was already requested in another post, but it was missunderstood. (http://kendoui-feedback.telerik.com/forums/127393-kendo-ui-feedback/suggestions/11578722-support-sorting-datasource-groups)

The idea is to allow for Groups in DataSources to be sorted in ways other than alphabetically; this will allow for certain groups to be given priority.

It would be good user interaction when multiple node selection is implemented.It saves lot of rework

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.

One should be able to group by a specified field, and then sort the groups themselves NOT by that field but by another field. For instance, it is currently not possible to sort data by its name but order it by its date.

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.

XML namespaces have a purpose and are extremely useful in maintaining data. The Kendo framework not supporting these is absolute insanity. I'm not interested in rewriting half of my data feeds to support a framework. 

If Kendo is intended to be "the world's most complete HTML 5 UI Framework," it should be supporting something as basic as this. If there's a valid reason why not to do so, I'd love to hear it.

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.

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.

Currently, an inherited DropDownList widget can only bind to another of the same type  or another vanilla DropDownList (via  alternativeNames array at kendo.all.js line 32813) 

A use case is that I originally created ParentCustomDDL and ChildCustomDDL with the intention of cascading from parent -> child. Since alternativeNames is hard-coded, I was forced to merge the code into one clumsy widget so that name matches name.

FYI - There are several related requests that have been voted by 100s of users and marked as completed. However, this support is only at the surface and not complete.

We need all kendo components to consistently support binding to more than just primitive properties but at a minimum to models with Id (for reference) and labels (for display).

Many kendo components support this simple concept with 'dataTextField' and 'dataValue' field, but as soon as we try to customize something seemingly simple (for example multi-checkbox filters on grid columns) we are left with custom coding because at that point kendo falls back to only supporting simple arrays of strings etc.

Thanks.

In order to clearly identify if a datasource operation is successful, 
two alternatives are possible:

1. Add success event to the datasource in order to get datasource operations separated from update, destroy, add. 

2. Enhance change event by error array. 
Currently, the change even is fired even in case of an error. So, at least an error array containing error messages should be available, together with a property "hasErrors".

Ignore language specific characters when filtering. Example: search phrase "Deja" should find word "Déjà".

"WebAPI now uses the DateTimeOffset time as a main type when it comes to dates. However DateTimeOffet requires the Model(that the dataSource creates) to keep information for both Date and Offset which is not possible with the current architecture of the DataSource and Model of Kendo." Based on http://docs.telerik.com/kendo-ui/aspnet-mvc/helpers/grid/how-to/oData-v4-web-api-controller
Please add full support, also when working with Dates. Thanks.

When retrieving data from a remote datasource with a fetchxml via soap that include link entites you get objects that have property names that contain dots like "account.accountid" for example. That doesn't work with Kendo Grid for example. Kendo always tries to go one level deeper if the property name contains a dot. Hence you always have to parse/refactor the results of a retrieve.

As requested in this thread:
http://www.telerik.com/forums/filtering-support-for-pivotgrid-pivotdatasource

I think it would be extremely helpful to offer the same level of filtering on the PivotDataSource for a consistent development experience (especially since PivotDataSource 'inherits' from DataSource:
http://docs.telerik.com/kendo-ui/api/javascript/data/pivotdatasource).

Thanks!

Currently when the add() method is called on a DataSource, if the id, as defined in the Model, is included, then the sync method is called, the data is not persisted to the _pristineData object, and neither the Create nor Update transports are called.  This has the effect of not persisting the data and so if the cancel button is pushed on an edit screen, the added object is mysteriously dropped.  

Please see my post on the kendo forums for a more detailed explanation including demos of the issue.  http://www.telerik.com/forums/if-id-is-provided-in-add()-sync-does-not-update-_pristinedata-and-create-update-are-not-invoked

I would suggest that anytime the add() method is used, it should be considered a 'new' record, or at least when the id provided does not match with any other id currently in the data array. If it matches a record in the data array, run the Update transport, otherwise, run the Create transport.  Simply including a value for the id should not remove the record from ever being persisted.

It is possible to retrieve IEnumerable collection from DataSourceResult, but there is no option to get IQueryable collection that has not been evaluated. I think it might be helpful to use filters from grid that can be used to generate a query.

Hello,

 I knew there was "set" function for kendo.data.ObservableObject, it could change value of specified field.

But after this action, we need call "sync" method for data source manually, and sync action will fire some events/ data bound again.

Is there another method, that we only hope sync value of specified field, without fire events and data bound again?

Thank you.
