ASP.NET MVC的CheckBoxList从列表属性模型 [英] ASP.NET MVC CheckBoxList from model with List Property
问题描述
道歉,如果标题是不清楚。
Apologies if the title is unclear.
我试图从形式ASP.NET MVC提交返回我的模型。
I'm trying to return my model from a form submit in ASP.NET MVC.
我的问题是几乎相同的this问题,只有在不同我没有列表与LT;产品型号>
但就像一个模型:
My question is nearly the same as this question, only differing in that I don't have a List<Model>
but a model like:
public Model
{
string UserName {get; set;}
string Password {get; set;}
List<Roles> UserRoles {get; set;}
}
在我需要的作为的UserRole复选框的管理员可以从创建一个新用户时选择。我的问题是,我不知道该如何对一个列表中使用@ Html.CheckBoxFor。我想这样的:
where I need the UserRoles as checkboxes that the admin can select from when creating a new user. My question is, I'm unsure how to use a '@Html.CheckBoxFor' against a list. I tried this:
@for (var i = 0; i < Model.UserRoles.Count();i++ )
{
@Html.HiddenFor(model => model.UserRoles[i].RoleID)
@Html.CheckBoxFor(model => model.UserRoles[i].Selected)
@Html.LabelFor(model => model.UserRoles[i].Name)
}
这丝毫不工作 - 每个页面上的标签是名,而我的列表是在POST空。谁能给我提供这个任何指导?
which in no way worked - every label on the page is "Name", and my List was empty in the POST. Can anyone offer me any guidance on this?
推荐答案
没有必要从剃刀走的。
这对我的作品:
for (var i = 0; i < Model.UserRoles.Count(); i++)
{
var role = Model.UserRoles[i];
@Html.HiddenFor(model => model.UserRoles[i].RoleId)
@Html.CheckBoxFor(model => model.UserRoles[i].Selected)
@Html.LabelFor(model=> model.UserRoles[i].Name, role.Name)
}
