Currently, when an event that is grouped by multiple resources is dragged, it automatically updates the selected resource data with the one that corresponds to the drop target.

The more appropriate behavior would be to be to automatically preposition the event for the rest of the selected resources.

We have a web page critical to the web application. In the absence of a suitable MVC widget we had to use a ASP.Net WebForm ListView control along with ASP.Net Ajax (Accordion for expand/collapse functionality) and JQuery (for client side validation). 
 
The web page accomplishes the following key functional requirements –
 
a. Ability to group products –  Using ASP.Net Ajax we were able to provide the expand / collapse visual effect.
 
b. Ability to enter order quantities very quickly -  a lot of stores place orders at the last minute  (5-10 minutes before order deadline) for valid reasons.  The web page provides a text box inline for quick entry.  On a desktop, the user can traverse the rows within the group using the tab key.   The web page typically contains 150 –  200 products for entry.   With Telerik MVC Grid widget, in the absence of inline editing, having to click on Edit/Update/Cancel buttons dramatically increases the number of clicks / touch / swipe.  Besides, it creates a real estate issue on smaller form factors.  
 
c. Real time validation – using JQuery we were able to validate the row as and when the quantity was entered.  Any error would show below the row in question.  The error would continue to show until the quantity was revised.  The error however, will not stop the user from entering quantities on other rows.  This approach lets the user review any errors in the end.
 

The closest MVC widget we could use from the Telerik collection was the grid widget with grouping.  However, it falls short on points b and c above.  There is probably some workaround available but then we would lose the LOW CODE advantage.

Create a PDF file viewer (like the one in WPF) so users can view PDF files in the web application. And can also control who can read, copy and/or print

It would be nice to have a MultiColumnComboBox as we have it already in WinForms.
A MultiColumnComboBox is a special case of combo box control with Grid integrated in its drop-down. The control combines the functionality and features of DropDownList and Grid.

Currently, if I want to bind an ASP.NET TreeList to an OData DataSource, I have to define the data source using a javascript object:

https://demos.telerik.com/aspnet-mvc/treelist/odata

https://demos.telerik.com/aspnet-core/treelist/odata

I would like to be able to be able to define the OData DataSource using ASP.NET Razor syntax just like the Grid:

https://demos.telerik.com/aspnet-mvc/grid/odata
https://demos.telerik.com/aspnet-core/grid/odata

Thank you.

as of today it is not possible to bind the map markers to signalr.
in grid it works. in kendo map not.

it would be blaze if the map markers would be a observable collection for mvc.this way you could update it through the viewmodel.

Row's hover effect should be optional and it could be enabled/disabled in grid's configuration, the same as we add Selectable, Navigatable, Sortable, Editable, etc., functionalities to grid. This could apply to odd/even coloring too. Should no need to do hacks to achieve this.

Many widgets offer functionality to define a template (header, row, toolbar or whatever) by an id, such a way that the id refers to a html section that actually contains the template like:
<script id="idOfSomeTemplate" type="text/x-kendo-template"> 
<!-- template contents --> 
</script> 

I use this a lot because it's easy to use and whenever the widget is part of another widget (common example: a grid part of a tabstrip) Razor /C# won't allow you to do nested inline markup blocks (@<text> </text>). With the above template it's possible to define the tempalte outside the nested inline block.
Now it seems the MVC wrappers don't have the possiblity to do this for the grid toolbar template. 
TLDR:
I would have expected this templateid method:
@(Html..Kendo().Grid<T>() 
.Name("Grid") 
.ToolBar(toolbar => 
{ 
toolbar.TemplateId("idOfSomeTemplate") 
}) 
) 

In Kendo MVC Grid, the column of type Select() will be good if has an option to show/hide the checkbox in specific rows based on an expression. For example:
.Columns(columns =>
            {
                columns.Select().Visible(m => m.ShowSelect);
            })

Where "ShowSelect" is a property of my Model which is bound to the Grid.

You recently added a checkbox column feature to the grid control. However, you cannot control at the record level if that checkbox should be accessible. Every checkbox is selectable regardless of the data it represents. It would be nice to disable (or hide) the checkbox in the column based on some criteria in the record. 

Possibility to iterate over all manually defined columns and f.i. set width or any other property. 

Hi  I have some question the "ustr" i want use diagram  "https://demos.telerik.com/aspnet-mvc/diagram" link and i don't know what code it's use in method 

public ActionResult _OrgChart(){return Json(DiagramDataRepository.OrgChart(), JsonRequestBehavior.AllowGet);}

please i want to help what i do

It would be nice to have an option to supply the Grid control with a default filter operator as shown below.
The current workaround is long and error prone, because you have to redefine the complete list, the default filter has to be on top. So the ordering matters, that is always a bad idea.

Filterable(filterable => filterable
    .DefaultStringOperator(StringOperatorEnum.Contains) 
   )

The datasource for ComboBox object does not support lambda expressions like ListView (and many other objects). These 'hardcoded' strings are error prone and is causing headaches when altering modelschema's.

DataSource(ds =>
    {
        ds.Custom()
        .Sort(sort => sort.Add("PropertyName").Descending())
        .Transport(tr => 
            tr.Read(read => read.Action("Action", "Controller"}))
        );
    })

Please take a look at this issue where DDLs and CoboBoxes won't submit their values the second time after validation fails and the required field is entered.
This was reported back in 2015 and is still unresolved.

Just like RadRibbonBar - Telerik ASP.NET AJAX RibbonBar, populating it from xml. 

We need similar control for MVC. If similar solution exists can you provide me with some examples. 

Thank you 

Make the TreeList wrappers support the same functionality as the Kendo UI TreeList.  Make the method Height support also string values

In Kendo editor 
Add lines of text with and leave gaps in between lines
Try to copy text by selecting all text
All empty line breaks are erasing itself and left only texted lines but not empty lines
This behaviour found only in 2017 release

You can find this behaviour even in kendo edito demos

Cancellation token is widely supported in entity framework. And it has big benefits for long running queries to allow cancel them.

ToDataSourceResultAsync methods should support passing cancellation token as a parameter.
