有没有办法,我可以在页面加载或发布到服务器时预先选择一个项目..

这就是我现在所拥有的……

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

解决方法

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