如何动态预选ASP.NET MVC中的html.DropDownlist中的项目

设置SelectList的SelectedValue属性,或将其作为第二个参数传递给SelectList构造函数.

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