add delay parameter in miliseconds for the kendo.ui.progress so you don't see your container blinking if your ajax calls are fast.
Hello,
As kendo.ui.progress is a function the optimal solution here would be to rather call it when the loading indicator should be displayed. In integration scenarios developers should implement this timeout logic on their own. In regards to our components we can expose such a property per component that would force the loading indicator to show if data is not loaded until N amount of milliseconds.
