禁用dropdownlitFor时，值始终传递为0

Question

这是我的dropdownlistFor

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

如何传递已存储在objTicket.DepartmentId？

中的值

如果我更改删除禁用=“禁用”，我会得到正确的值。

Answer 1

使用名称而不是ID提交表单字段。浏览器不会提交已禁用的控件值。放置一个@Html.HiddenFor字段，其中包含相同的名称和不同的ID，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" })
