I'll check the link. the updatepanel is only containing the three comboboxes and all of the have static access "no db access". all it suppose to do is show and hide the combos

will it overcome the delay problem in Ajax updatepanel ??

i have cobmobox (chapters_combo) with visible= true and another two combos with visible = false i want when selecting chapter1 from chapters_combo then make the first combo visible = true and selecting chapter2 from chapters_combo then make the second combo visible = true chapters_combo has autopostback = true the problem each time selecting an item from chapters_combo the whole page update. is there any way do overcome that. i tried to use Ajax updatepanel but it takes about 15 sec to show the combo.

i have a wen application using asp .net 2 and ajax extensions. I'm using ajax to show some text boxes when selecting items from combo box without refreshing the page. the code works normally on local machine, when uploading it to the hosting server i noticed that when selecting item from combo it take about 14 sec to show the text boxes. how can i decrease the delay between Ajax request and response?or this delay is normal ?
