     "December"}), 
    new { onchange="this.form.submit();" })%> 

Answer 1

設置的SelectList的SelectedValue屬性，或者把它作爲第二個參數的SelectList構造函數。

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