Q:

How to rest a DropDownList after Post

Trying to rest my DropDownList in my c# Web app when a user clicks the submit button. How can I reset it to the default when it does a postback? Can someone give me an example? 
Many Thanks

A:

if(IsPostBack)
 {
   dropdownlist.DataSource=null;
   dropdownlist.DataBind();

   }
