How to keep dropdownlist selected value after postback

Question

In asp.net mvc3 how to keep dropdown list selected item after postback.

Answer 1

Assuming the selected item is part of the post, the controller now knows what it is. Simply have an entry in the ViewData dictionary indicating which item should be selected (null on get or if nothing was selected). In the view, check the value and if it's not null, select the appropriate option.
