Better intro and walkthrough for getting started with KendoUI in real-world context

I've already seen too many forum post about problems, so I'm looking for a better intro and walkthrough for getting started that does NOT make any assumptions.

Yes, I understand that KendoUI is HTML5+jQuery+CSS but when building multi-targeted mobile apps for iOS, Android, etc must the HTML5 app be served from a web server? Or will it be accessed from an app installed on the mobile device after packaging with PhoneGap? So that the HTML5 web pages are actually packaged into the app that is installed on each mobile phone device?

And if packaged with PhoneGap, where do you start: with a PhoneGap project? Or with a Visual Studio project? Especially if you want to build upon existing ASP.NET project dll's and ASP.NET MVC3 or MVC4 projects?

A complete walkthrough clarifying which development steps to complete in which development environment would prevent time wasted on trial and error. Especially for the situation where I want to develop in Visual Studio with ASP.NET MVC 4 plus KendoUI on PC Windows, then eventually get to an iOS app for iPad and iPhone on Apple.

Slider and Graphs

Is it possible to have a slider on graphs. We have a lot of data to graph and presently it just makes the columns or bar smaller trying to fit everything in the area allowed. I have attached an exemple to show what we would like to have.

Thanks in advance.

Disable Sort in some columns

Hello,
I have a grid being populated through a json data source. I can enable sorting on the grid by setting the sortable property to true. This enables sorting on all of my grid columns. Is there a way to enable sorting for particular fields only? So if I have a grid with 3 columns, I only want the users to sort by the first or second column.

Thanks in advance.

How does one adjust the display value for grouping?

I've got a grid that is declaratively bound:

data-role="grid" data-bind="source = logEntries"

One of the columns is a Log Level column. The data source field (Level) is an integer. I have that column declared with the template

"template": "#= viewModel.getLogLevelAsName(Level) #"

that converts the integer into a human-friendly display name. A human doesn't know the difference between log level "2" and log level "5" but certainly knows the difference between log level "Debug" and log level "Error." This works out great because when the user sorts, they are sorting on the relative underlying value (the log level number) and not the display text.

That said, when I group by that column, the underlying data (log level number) shows to the user (see attached screenshot). I'd like to run that number through the same

viewModel.getLogLevelAsName(...)

method.

Or maybe I'm missing something? For example, some baked-in way to provide a lookup (display) value for items in a grid (besides using a manually-written template)? Something like the ability to assign a column a "lookup data source" (data-display pair) so that the underlying data is always shown to the user based on the results of the lookup.

WCF CRUD Demo Fails on Add Record

Hi All:

Pretty sure it's a configuration issue. When I load the WCF CRUD demo into Visual Studio, build, and run, I'm getting the following message when attempting to add a new record (grid is initially blank, btw):

Error: 'ProductID' is null or not an object.

Configuration uses SQL Server 2008 Express. Could that be the problem, I wonder?

Editor in Chrome

Just a small tip for everyone out there....
If the editor appears 'disabled' in Chrome (like in the attached screenshot) the likely reason is that it's been initialized outside $(document).ready().

Just move it inside $(document).ready() to fix it. I found this out the hard way :)
