When endless scrolling and grouping is enabled on the KendoUI grid, collapsing large groups causes the grid to load ALL the hidden detail rows into the DOM.

This takes a very long time for the grid to do, as well it violates the whole point of a paging system. (ie I only want you to load X records at a time). Afterwards the performance of entire website (including the grid) will be very poor since potentially thousands of rows have been loaded into the grid and then immediately hidden. Additionally, these rows do not add any value to the user, since they are all hidden anyways.

When a category is collapsed, the grid should NOT add any new rows for that category to the DOM.

I have included a sample that demonstrates the performance issues.

Especially with dark themes such as Metro Black, the traditional browser scrollbar does not really fit. I know scrollbar customization is not available in all browsers, but no fallback support is required (as the css is simply ignored by these browsers), and I believe it would greatly benefit users of the browsers that are supported.

The filemanager provides no way to open file by keyboard: "enter" renames a file and "space" selects it.

According to https://docs.telerik.com/kendo-ui/api/javascript/ui/filemanager/events/open files can be opened by double-click.

As per the .NET format support shown here:
http://stackoverflow.com/questions/11731996/string-format-numbers-thousands-123k-millions-123m-billions-123b

And here:

123456789.ToString("#,##0,") will return "123,457".
123456789.ToString("#,##0,K") will return "123,457K".

kendo.format("{0:#,##0,", 123456789) will return "123,456,789".
kendo.format("{0:#,##0,K", 123456789) will return "123,456,789K".

As per the .NET standard, each trailing comma will round off 3 digits, so 123456789.ToString("#,##0,,M") will return "123M".

According to https://docs.telerik.com/kendo-ui/controls/data-management/filemanager/context-menu:

You can define your custom items which can execute custom commands

However, no option allows me to configure my own commands.

I managed to hack this: https://dojo.telerik.com/@GaloisGirl/iLoHIhoh , but it's an ugly solution.

Please support the ImageBrowser as a standalone control.

It would be nice to have the possiblity to toggle edit mode on and off for the Grid.
Use case: Often users find things that need changing whilst browsing data. In those cases it would be nice to have a toggle button in the toolbar that enables and disables edit mode. n quiting edit mode the users

Right aligned columns are common for number fields and it would be nice to simply set a property in HTML and/or the view-model:
E.g { "field": "amount", "align": "right", "title": "Amount", "width": "110" }

Add capability to upload .mpp file and populate the GanttDataSource, GanttDependencyDataSource and Resource Assignments. Thanks.

Great work on this control boys.... I reckon it needs Filter Row, Multiple Column Sort, Paging to make it consistent with the grid.

Allow to have different child groups for each parent group

Example:
 ___________________________________
 Meeting Room 101     |   Meeting Room 201
 ___________________________________
 Alex  |  Bob                 |   Charlie
 ___________________________________

Right now there are two options for sorting, single and multi-column. We would very much like to use the multisort version, however our users fail to understand the functionality. We suggest a new setting, "ctrl-multisort":

Single-sort when clicking and multi-sort when ctrl-clicking, similair to most desktop grid controls.

Ability to change a treeview node's description (node text) inline on the fly

I'd like to add a "download" option to the context menu, but only for files, not folders.

Here's what I have so far:  https://dojo.telerik.com/@GaloisGirl/iLoHIhoh
 

Add marker clustering support to the Kendo UI DataViz Map control.
If you are viewing a map with many markers nearby, they should group together so that the map is more pleasing to the eye.

This functionality already exists in the Telerik Silverlight Map control and it would be great to see similar functionality here.

Here's an example of what I want: http://demos.telerik.com/silverlight/#Map/Cluster

I am using Layout and View....

How to I change view by swiping ?

Kendo Scheduler should have iCalendar Export (in similar way to ASP.NET Ajax Scheduler).

It would be exponentially helpful if the "ObservableArray" implemented some basic "Where/Select/Single" methods. This would assist in searching through them and give Kendo UI a much needed facelift in the array department.

Behavior would be, theoretically, as follows...

var viewModel = kendo.observable({
    Users: [
    {
       id: 1,
       name: "Stacey"
     },
     {
       id: 2,
       name: "Dylan"
     },
     {
       id: 3,
       name: "John"
     }
 ]
});

var idSearch = 1;

var result = kendo.Search(viewModelArray).Where(function(x) { return x.id == idSearch });

or ...

var result = kendo.Search(viewModelArray)
.Single(function(x) { return x.id == idSearch });

or possibly even chained like in "linqjs"

var result = kendo.Search(viewModelArray)
.Where(function(x) { return x.id == idSearch })
.Single();
