I find ButtonGroup for mobile framework very useful to desktop (classic) web application too.

Could you add this widget to web framework please?

An important configuration is to choose if have comportament like "checkboxlist" or "radiobuttonlist", and for sure its orientation, vertical or horizontal. 

The tools should have all the options as the javascript for example: Gantt custom views can only be used if you use the JavaScript version.  The lack of full support defeats the point of buying a MVC wrapper.

I would like to see a separate assembly that can be referenced both on ASP.NET MVC and Application server side and that the DataSourceRequest can be transformed into a DataSourceResult on the Application server side and sent back to the website.

At the moment this is not possible due to the non-generic definitions of the DataSourceRequest and DataSourceResult classes. 

Referencing Kendo from the Application server side also requires references to System.Web and others that shouldn't be necessary.

Statically typed transport serialization should be supported, as required by WCF, Message Queuing or even Protobuf. Such transport mechanisms are required by N-Tier environments.

At the moment, if all DataSourceRequest's should be processed on a web server and propietary database licensing is in effect (ex. for MSSQL) where the cost is per port, it would end up being very costly.

Current Telerik MVC wizards for converting a project or creating a new Telerik project adds all possible Telerik files to the solution and also new Views under the shared folder.

As it is now, I include about FIVE Telerik script and css files in my views, but my project includes about 600 Telerik files in the /content and /script folders together. That is not ok and makes for very large and unnecessary complex solutions containing mostly unused code that makes the project difficult to overlook for an outside developer. In our company we like the solutions to only include files that are actually used and not alot of dead code.

Also, it is difficult to know which files that is possible to delete since there might be internal dependencies between kendo files.

It would be great to be given some choices in the wizards, like would you like to install everything or answer a few questions to do a custom installation. Things that are unnecessary are for example to include localization and globalization support for All possible languages even though the user specifies only German support, and also to include the files for all possible themes even though the user specifies the Metro theme. Then you could add a change project settings wizard where the theme or language or other settings could be changed. The wizard would simply change the included .js and .css files. Also the *.cshtml files in the Shared folder should be optional to install, not always included. Those are just examples, it would be great to customize the installations as much as possible.

The "CreateDataSourceResult" function verifies if the given DataSourceRequest "Sorts" list is empty and if the IQueryable provider is Entity Framework. If both are true, it adds a default OrderBy to the query on the first sortable property. This makes sense as EF must be ordered before skipping items.

The following statement checks the given DataSourceRequest and IQueryable:

if (!sort.Any() && queryable.Provider.IsEntityFrameworkProvider())
{...}

This leads to unwanted behavior if the query is already sorted on the server and the corresponding SortDescriptor is removed from the "Sorts" list. This is needed if we want to sort on a viewmodel property that doesn't exist on the EF model.

An additional check should be done on IQueryable to see if it is already ordered to avoid replacing the existing OrderBy with a default one.

if (!sort.Any() && queryable.Provider.IsEntityFrameworkProvider() && queryable.Expression.Type != typeof(IOrderedQueryable<TModel>))
{...}

Take the look and feel of the UI for IOS gauges, for instance the linear gauge, and duplicate that into a more customizable gauge tool set.

Particularly, the ability to gradient linear gauges, remove ticks and round the edges. Similar to a progress bar with a value marker.

That will make web pages load faster

There is No Model Binding feature available for DataTable.ToDataSourceResult() Function, Implementation of this feature makes Kendo UI much interesting.

At present to get the nice kendo checkboxes you need a checkbox followed by a label, you can't do this in asp.net mvc because

@Html.CheckBoxFor(x => x.IsEnabled)

renders as:

<input id="IsEnabled" type="checkbox" value="true" name="IsEnabled">
 <input type="hidden" value="false" name="IsEnabled">

The solution is to use the kendo mvc dll, or possibly just make your own, but it would be much easier if the kendo ui code could just ignore the hidden input, or if the two controls could be linked via 'for', 'data-for', 'data-whatever'

It seems that the default behavior of the control is to set autocomplete="off".  When setting using the .HtmlAttributes method int he MVC wrappers and setting autocomplete to something else this setting is ignored.

I propose that the HtmlAttributes method should adhere to all settings that are passed into it.

Example using the MVC Wrappers:

html.Kendo().MaskedTextBoxFor(e).Mask(mask).HtmlAttributes(new { @class = "form-control", autocomplete = "tel-national" })

I'am looking for an event like "onDeleting" in my multiselect box, so I can confirm it or not. The current "onChange"-Event triggers to late. 

I would like the possibility to use client details templates for server bound grids (and maybe other components). That is - the main grid should be fully loaded when the page loads (without ajax requests), but the details should be loaded on demand (when clicking the > icon) via ajax.

Nowadays, was promissed exporting Gantt to PDF.
It is not working. Just prints what you see. It is very limited.
Should allow: 
1)  option like "allPages" to print all Gantt Diagram in any page format.
Making a "printscreen" of the visible gantt it is any solution for any project. 


2) Export Gantt data to excel.

ToDataSourceResult is very very slow on Large datasets - getting the Total Count is the issue, have an option to omit the total count or provide a way to inject the total count with some more efficient code.

There is no reason it should use the default maxJsonLength; especially since it is inaccessible to change.

Of the highest priority, we desperately need file explorer for inserting and uploading images.  In the AJAX editor, this appears to be build off the radFileExplorer control which is the other one we REALLY need for MVC which doesn't exist at all.

Currently, it's very difficult to set up a grid that has a calculated column, where the result is not editable by the user.

It's pretty easy to set up a javascript function to calculate and update the value using `dataItem.set("Column", value)`, but this does not work if the column is not also Editable.

Currently, you need to hack together some kind of text replacement for the Editor Template, and there doesn't appear to be a simple way to do this from the MVC wrappers. You can create a disabled or readonly textbox, but I'd prefer that it looks like those columns where Editable is set to false.

Please implement more Grid-parity features for the TreeList widget. Unfortunately, the filter for enum values shows only a numeric up/down on a TreeList. Change this behavior to match the Grid filter: here, enum values are shown with their textual representation (and, if provided, the [Display] attribute is evaluated).
