當dropdownlitFor被禁用，值始終爲0

Question

傳遞這是我dropdownlistFor

@Html.DropDownListFor(m => m.objTicket.DepartmentId, new SelectList(Model.objTicket.Departments, "DepartmentId", "Department"), 
"-- Select Department--", new { id = "Deptment"}, disabled="disabled") 

如何傳遞已經被存儲在objTicket.DepartmentId價值？

如果我更改刪除disabled =「disabled」，我得到我的正確值。

Answer 1

表單字段使用名稱而不是ID提交。瀏覽器不會提供禁用的控件值。放置一個@Html.HiddenFor字段，其​​名稱和ID不同，如下所示。

@Html.DropDownListFor(m => m.objTicket.DepartmentId, new SelectList(Model.objTicket.Departments, "DepartmentId", "Department"),Department--", new { id = "Deptment"}, disabled="disabled") 
@Html.HiddenFor(m => m.objTicket.DepartmentId, new { id="Deptment2" })
