Add data-debug=[true|false] attribute to all widgets to get verbose logging in the console to help debug declarative binding
Declarative binding is sometimes difficult to debug and might benefit from getting verbose logging in the console.
There is obviously a trade-off considering the size of files but this feature might only be available in the non-minified version through the build process.
Additionally, we plan to introduce another tool to help you inspect and debug Kendo UI widgets when rendered in the browser. Stay tuned for our next major release in mid March.
Besides, being able to set which widgets shall log information is a plus.
Using sourcemaps would require that you know where to have a breakpoint in the first place. With layouts, views, widgets and MVVM binding all set through declarations, I have experienced cases where having a verbose log would help determine where to set your breakpoints.
