AutoComplete Populating will repond to each key typing for when you input data in AutoComplete.
Is it posssible to set time interval to respond key typing?
For example, set MinimumPrefixLength=3 for an AutoComplete. If user input "School" in the box with within 3 seconds and time interval is set as 5 second, then Populating event only fired one time, otherwise it will be fired 3 times, if Populating connect to async call, that will be a big issue for performance.
