Question

Greetings all,

Is there a built in way to know when a user is done typing into a textbox? (Before hitting tab, Or moving the mouse) I have a database query that occ

It depends on what you mean by "done typing." There is an event to let you know when the user has left focus of that particular control. Also, there is a changed even that tells you when the text changes. What you could do is trap two things:

1) Lost focus

2) Every time the user changes the text, start a timer for say, 20 seconds, and if the user is done within that time, then the user is "done" typing. That is if the user has not done anything within that time then assume the user is "done."

If either of those two things occur then the user is done, make sure to stop and restart the timer appropriately. Obviously, you could change the timeout.

It all depends on how you want to define it.
