timeout

   We have a form with two reportcontrols on it. One for the master tabel and one for the detail. 
When the user selects a Master the selectionchanged trigger is fired and there we lookup the detaillines for the selected master and show them in the detail reportcontrol.
This works fine. 
What i want to avoid is that when the users scrolls down very vast, the trigger is fired everytime (which requires a lot creates, deletes, databaseaccess,....).

Is their a way to 'postpone' the trigger for a certain number of milleseconds? So the trigger would only be fired if the user stays on the same line for lets say 250 milliseconds?

If not, any other ideas how to do this?

Thanks in advance.

	The Basic idea is: Move the code in selectionChanged to a Timer Control and set this timer in selectionChange event. Something like : in Timer event: timer.enabled = false ' do your code in selectionChangedEvent : timer.enabled = true timer.interval = 250 ---------------------------------------- I my case (MS foxpro) every time the selection Changes the timer is restarted, so nothing happens until the user stops the selection...
