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 :)

not to display aggregated field in grid

When I aggregate a grid on a certain column, the column will be displayed in the groupheadertemplate of the field. The problem is that the field is also displayed in the grid as a column. Is there a way to disable this column in the grid and only show the groupheader template?

ComboBox width not matching other elements.

I'm trying to set the width of controls in my form but I noticed that the combobox tends to be a little shorter than the other elements with the same width.
Here is a sample http://jsfiddle.net/sitty/PLdGS/8/ I have one input text control and another kendo ComboBox both with width set to 300 but the combo box appears to be a little shorter than the input control.
