DropDownList doesn't postback on SelectedIndexChanged

Question

I\'m writing an ASP.Net webform with some DropDownList controls on it. Then user changes selected item in one of dropdowns, ASP.Net doesn\'t seem to handle SelectedIndexChan

Answer 1

if you are populating the dropdown list during page load then each time the page postback it will reload the list thus negating your postback method. you need to be sure to load the dropdownlist only if (!ispostback)
