Why can't a Layout take a viewModel like a View? Something like this:

<div data-role="layout" data-id="service" data-init="init" data-model="viewModel"></div>

As a workaround, I am doing this the following. Is there any reason that I shouldn't be doing this?

<div data-role="layout" data-id="service" data-init="init" data-show="show"></div>

function show() {
  kendo.bind($("service-layout-selector-here"), viewModel);
}

Hi Bart,

Layout view models are not supported purely due to implementation complexity. The layout header and footer are "moved" to the current view DOM element each time the view changes. this would break the mvvm bindings, which rely on a strict DOM hierarchy.

OK. Can you give me a recommendation as to the best way to do something like this then?

http://bit.ly/16ur63D

Do I need to repeat this "header" information within each view? Or perhaps I can have two views going at once? One for the header information and another for the body?

Hi,

If I understand you correctly, I do not think that you need MVVM binding for handling the button group event clicks - you can use declarative event setting instead.

Hi,
Is it still the case that there is no straightforward means to use Layout with separate viewModel html files?  Is the real choice "viewModel OR layout widget"?  

Thanks

Hello David,

my previous response still holds true - ViewModel bindings are not supported for the layout parts. Of course, a view may have both a ViewModel and a layout attached, so I would not consider this an "or" situation.
