Hi Sankar.. There are many ways in using Ajax..I use a .dll to work with ajax..AS like Ramana said capture the dropdownlist events with javascript and that works fine,but the thing is that u have to go for functions sacrificing the dropdownlist_selectedIndex changed property.. Regards,

i think you can use html control and fill the drop down when page loads. this will load the datas when page loads and minimize loading time.
