RadAutoCompleteBox needs a Delay option to delay the retrieval of data while user is typing - in milliseconds.
Hello Guys,
The public server-side property is called RequestDelay and will be available as of R1 2020 release due in mid January 2020.

I agree completely!
This would be similar to the ItemRequestTimeout in RadComboBox.
