Set the SelectedValue property of the SelectList, or pass it as second parameter to SelectList constructor.

<% = Html.DropDownList ( "dllMonths", 
                           new SelectList ( new List ( ) 
                                          { "", "January", "Feburary", "March", 
                                            "April", "June", "July", "August", 
                                            "September", "October", "November", 
                                            "December" },
                                          "April" ), 
                           new { onchange = "this.form.submit();" } 
                       )%>

I would go a little further and say that you should use an overload with the selected item argument.

i think that was what i said :)

He gave two choices; I'm saying the first is really the only acceptable one. But I did up-vote since he got it right.

yea, actually i would agree on that. It will probably save a function call as well i would think
