Question

I have an updatepanel which displays or hides a new control when I click a checkbox. But the problem is that is is very slow. From the click of the checkbox until the visual reaction occurs almost 2 seconds are gone.

I think this is due to the asynchonous callback. The client seem to wait 1-2 between each callback to fire. Is this true? If yes, is there a setting which makes callbacks to the server occur in instant time?

EDIT It seems i’ve hit a known bug, but the offered fix doesn’t work for me:

Answer 1

It seems that the UpdatePanel of DevExpress solved the problem in its latest version.
