当dropdownlitFor被禁用，值始终为0传递 [英] When dropdownlitFor is disabled , value always passed as 0

问题描述

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")

我如何能够通过已经存储在 objTicket.DepartmentId ？

如果我更改删除禁用=禁用，让我的正确的值。

If i change remove disabled ="disabled", i get my correct value.

推荐答案

表单域使用的名称，而不是IDS提交。禁用的控件的值不会被浏览器提交。将具有相同名称和不同的ID的 @ Html.HiddenFor 字段如下。

Form fields are submitted using Names instead of Ids. Disabled controls values wont be submitted by browsers. Place a @Html.HiddenFor field with same name and different Ids as given below.

@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" })
