hi all

i am new in ajax.net

i have two dropdownlist box in my page. in that first ddl is fill when the page load. second ddl is filled based on the selection of first ddl. finally i want to insert the selected ddl items in database. my friends suggest better u use ajax for this. but i dont know how to use ajax in my web page.

i am using .net vs 2005.

i need your help. pls tell me what is the procedure to do this. i want to install ajax.net? or i want to download ajax components or ......

 install the ajax Extension on your machine and after installing the ajax extension put the both dropdownlist in updatepanel. Make the Autopostback=true of first dropdownlist and load that dropdownlist on page load. On the First Dropdownlist index changed write the code to fill the second dropdownlist. Your page will not be refresh as you have use update panel. So when you change the index of first dropdownlist only the index xhanged function will be called and this function will fill the second dropdownlist depending upon the first dropdownlist value

no need to use ajax for this just store the selected item text in a string varaible

and use the insert or update sql statement  to store that value in database table field

hope this will solve the problem
