When I bind this element: <select data-role="dropdownlist" data-option-label="Select an item" />
the optionLabel is not used.
This is because optionLabel is not in the default DropDownList.options object.
If I add the field optionLabel: "" to it, then the attribute is used correctly.

Due to the way the binding is working all possible configuration options must be in the default options object of the widget else it will not be possible to read the attribute in kendo.initWidget.

I can imagine that is applies to other options and to other widgets also.

Regards, Jaap

Hi,

 
The described issue is already addressed and the fix is included in the last internal build of Kendo UI. I will suggest you give it a try.

Can we bind data-option-label or template with observable ? 

 data-option-label="data-bind= html:varObservabel"

Or 

data-option-label="varObservable"

 

var viewModel = kendo.observable({

varObservable:"select somthing..."
      });

Hello Kevin,

Widget does not expose built-in MVVM binding for optionLabel update. I would suggest you implement a custom MVVM binding that tackles this functionality. Basically, it will need to update the optionLabel of the widget using its setOptions method.
