i don't know what is the problem?

Answer 1

Not sure what the exact scenario is, but every time you postback, you'll have to create the drop down list and register to the event. Couldn't you hide/show and populate the dropdown box on click of the button? Have a look at the link for a similar issue.

Haven't tried this myself, but this link might help you, if you must add the control dynamically http://shawpnendu.blogspot.com/2010/04/runtime-add-dynamic-dropdownlist-and.html

Answer 2

did you set ddl.AutoPostBack = true; when adding control runtime?
