Hi
It is possible to create a form layout with navigation toolbar to navigate between records?

In windows application you can use textbox and other controls and bind this controls to datasource and use navigation toolbar to navigate between records.
Also this form layout can design for master-detail layouts with grid widget or other widgets.

The Upgrade Wizard should provide an option to only update currently used skins rather than adding all skins each time a project is upgraded.

Create:
Html.Kendo().Grid()
.ToolBar(commands => commands.Create(Model.EnableCreate))
where EnableCreate is a bool.

Next is Edit and Destroy:

columns.Command(commands =>
{               
     commands.Edit(item.EnableEdit);
     commands.Destroy(item.EnableDestroy);
})
where item is the dataitem of the row and EnableEdit and EnableDestroy is bool properties.

Please go through this thread.

Even if we are allowed to add additionalData in the Grid's Read method, that data is not properly passed on to the corresponding ViewModel on the MVC controller action. I had to write JS using the dot notation for objects and indexer for arrays to get it passed properly.
My request is, if the additionalData is already json, allow it to be passed properly.

It would be awesome, if an automatic sanitizing of the ColumnName property would be implemented in one of the future releases of the MVC.NET.

Reason: When binding a DataTable to the MVC-Grid and using client side pagination, a Javascript error occurs if any column inside the DataTable contains a character which is not allowed in Javascript variables (like spaces).

Please consider adding a short-hand method to set the id of form element widgets such as:
Html.Kendo().DatePicker().Name("StartDate").Id("FormA_StartDate");

The code above looks a lot cleaner and more fluent and the one below.
Html.Kendo().DatePicker().Name("StartDate").HtmlAttributes( new { id = "FormA_StartDate"} );

This really comes in handy when building large single page application (SPA) where many entry forms are loaded onto a single page. Manually setting the Id property for widget elements help avoid potential html elements' id conflicts when we have Kendo form widgets of the same name.

Please add IntelliSense support for Angular directives in Visual Studio 2013 so this won't cause the 'green underline' error message.

<div kendo-grid="myGrid" k-data-source="customerDataSource"></div>

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).

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.

Not sure if this problem is specific to the MVC wrappers or not, but right now, you can not access a kendo control from document.ready unless your code is output after the control is rendered.  That is counter intuitive to the way document.ready is generally used - it should not matter where the code lives on the page.  The solution I would like to suggest is to add init events to the controls, so code can be run when the widget loads on the page, without the order of code mattering on the page.  Here is a related support ticket for reference:

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.

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

make the Kendo UI Menu switch from horizontal to vertical layout, depending on the browser viewport size.

I'm using NumericTextBox in ASP.NET MVC now, and I don't see it support Mouse Wheel like control for ASP.NET AJAX?

Using Visual Studio Enterprise 16.0.0.

Created MVC Project 4.6.1

Run Telerik utility to "Convert to Telerik Web Application" from Project context menu. On a clean project just created from the VS Template.

Since previous step errors out and doesn't complete an attempt was made to use the Telerik Upgrade Wizard.

This produced the following error: 

An error occurred while running the wizard.

Error executing custom action Telerik.VSX.Actions.ShowConversionLogAction: Could not instantiate a TextTransformation object from the compiled assembly. The following Exception was thrown:

Security Trimming feature will call AuthorizeAttribute.OnAuthorization internally, it would be nice to make sure that IsAccessibleToUser is thread safe.

Thanks
