This question is not specific to language/framework/platform.
I want to know (and confirm), what should happen (by default) if a user taps and holds (or clicks and hold).
This is more about basic usability and user experience.
What would a user expect to happen if the user taps(or click) and hold.
For some clarification I did read this: https://msdn.microsoft.com/library/windows/apps/br208928
The framework where I need to work on currently triggers holdstart if you hold for more than 400ms, and that in turn triggers tapcancel. I am not happy with it, thus want to know what is the more appropriate default behavior a user would expect.
