When using Html.Kendo().DeferredScripts() possibly bundle all the controls initialization in one single jQuery initialization function, instead of a call for each of the deferred controls.

I need configure in my Razor View, with my Multiselect helper, the maxselectedItems property (like others properties: MinLength, Filter,etc)

As a suggestion for future development, make Kendo compatible with RazorGenerator.Mvc per this link: http://blog.mirajavora.com/re-use-mvc-views-across-projects-with-razor-generator

I want to load a particular ViewModel into a treeview but using the MVC wrappers does not allow for setting what field will be the Id, and the hasChildren property. The model information can be set via the JavaScript configuration though.

It would also be nice to mark additional data on the model that should be sent to the Read action along with the Id from my item.

Just getting started with Kendo Grid - below is my VB.NET razor code (I know, I know) working against a System.Data.DataTable for a model. 

The DataTable contains columns in it where some of the ColumnNames have spaces. The web page successfully renders my table, but, it errors due to the Kendo's row template, it seems.

    Dim mainGrid = Html.Kendo().Grid(Model.MainTable) _
         .Name("Grid") _
         .Columns(Sub(cols)
                          cols.AutoGenerate(True)
                  End Sub) _
         .DataSource(Sub(dSource)
                             dSource.Ajax()
                     End Sub) _
        .Pageable() _
        .Sortable() _
        .Filterable()

The Multiselect control hardcodes the style of the Placeholder to Arial, 13px. Please make this either have HtmlAttributes or put a style on it, that can be overwritten.

Ability to write c# code or use model property value instead of just bool value to hide or show a cell(.hidden())

The documentation wrongly says that the grid will perform all server operations of paging, sorting, grouping, and aggregating whether bound to an iQueryable interface or a DataTable (http://docs.telerik.com/kendo-ui/getting-started/using-kendo-with/aspnet-mvc/helpers/grid/faq).

It turns out, after an extensive support ticket, that the documentation is plainly wrong. I have been told that only the COUNT() aggregate is supported when doing server side operations and bound to a Grid.

My request is that this gap in functionality should be fixed so that server operations work for both iQueryable datasources and DataTables.

Currently Jun 2014, when saving new data on hierarchy (parent/child) grid, there is no possible way to save the header data, get the pk of the header and pass the pk to child data and save the child data. 

I suggest to add a feature to auto save both parent and child data when user click save button when creating new data.
Basically do ajax save for the parent, on success pass header's pk to do ajax save for child.

It would be nice to handle editor template directly in the grid's configuration. Very often we have to use a simple custom editor but we end up creating a new file every time.

Html.Kendo().Grid<Model>()
.Columns(cols=>
{
    cols.Bound(m=>m.SomeProp)
        .EditorTemplate(@<div>
            Html.Kendo().ComboBoxFor(m=>m) [...]
        </div>);
})

Please consider adding charting capabilities to Pivot grid control.

When deleting or editing a series on the Scheduler, there is no option to edit/delete "all subsequent events".  Quite often, when editing a series, users will want to adjust the selected event and all subsequent events when editing a series.  iCal, Google Calendar, Outlook all support the option of editing a series in that manner. 

I would like the Kendo Scheduler Occurrence popup that contains the "this event only" and "entire series" options to also have options that include 
"all events in the series before the selected one"
"all events in the series after the selected one" 
like other calendar implementations.

Thanks

I try to use Export to excel feature i.e. recently added but it not export  data for Hierarchical Grid data as Expanded all rows.

Currently, binding to typed datasets is only supported after dataset is cast to its untyped version (typedDataset as DataSet).

This dictates using strings for columns declaration of Grid instead of lambdas:
  .Columns(columns =>  {columns.Bound("Name");})
and not 
  .Columns(columns =>  {columns.Bound(x => x.Name);})

It might be very useful if Grid will support binding to typed datasets directly.

In cases where the number of tabs in TabStrip Control is big and they don't fit the container size I believe a feature where the exceeding tabs should appear in OverflowPopUp, like the way it happens on the ToolBar Widget is going to be highly acceptable. Currently there exists only one workaround in cases like this, which is, make the TabStrip scrollable. I believe this option is totally outdated

please add culture fa-ir

When returning data for a grid using the "Model.ToDataSourceResult(request, ModelState)" syntax, if there are any ModelState errors, the grid fails to load any of the data.  In addition to validation errors, I would like to be able to send back feedback messages that can be extracted client-side that would not affect the binding of the grid.

It could be convenient to have the editor templates directly added to the solution (in Views\Shared) when deploying the ASP.Net MVC nuget package.

It would be great to be able to dynamically add Multi-Header columns in grids. Something similar to this http://stackoverflow.com/questions/30808655/dynamic-multi-header-column-in-kendo-mvc-grid

It would be nice if the traditional HTML helper interface could be augmented with tag helpers for some of the simpler widgets. Dropdowns, date pickers, buttons and the like could all be good candidates for tag helpers.
