Introduction:-
In this article I
have explained how to bind a dropdownlist using Ajax.
Description:-
Some developers binding the dropdownlist directly in pageload.which will give
low performance to your site.Now a days every user wants to avoid unnecessary
postbacks during any events.Lets take a common example that I want
to bind a state list according to the country selection. I can do it in code
behind selectedindexchange event,but it will result performance issue as
discussed previously,so I will prefer to use ajax here.
