Has there been a suggestion to make a property to only display the updateprogress display after a certain amount of delay?

Some commands are so quick that a progress is more distracting and might seem like a postback since something pops up and goes away so quick.

For example, if I have a calendar control and I change the date, with an updatepanel this is happens flicker free and almost instantly.  But, if I have an updateprogress, the text or image I have will appear ever so briefly making it less smooth, defeating the purpose.  BUt there are other instances that might take 2 or 3 seconds that it works great

I'll second that.

Interesting idea. I don't know you'd achieve that though. If you say, only show after x milliseconds (ms), there is no way for one to know if the "busy" state will gone just 1 ms later [ or (x+1) ms in total]--and we'd be back at square one. Why not just change the visible state of your label/image controls to true only for tasks that are known to be long(er) running. For the case you mention, just have it set to false.

I agree, also, if you wait x seconds, say 2, it might complete in 3 seconds therefore achieving the effect you're trying to avoid.

Better, designate what controls will not fire off the progressupdate control.  If all I am doing is selecting a date, I don't want to show the progressupdate. If I am checking for events on a selected date, then I probably would.

 I think this is actually in the latest version of the update progress control.  I've been off of the site for 3 years and was just going through my old posts....
