TextboxFor传递文本,但RadioButtonFor不传递
本文关键字:RadioButtonFor 文本 TextboxFor | 更新日期: 2023-09-27 18:17:45
我试图传递一个RadioButtonFor模型。
控制器[HttpPost]
public ActionResult Contact(ApplicationCommentType model)
{
//send email here
//reload form
ApplicationCommentType appdata = new ApplicationCommentType();
appdata.CommentTypeData = db.CommentTypes.ToList();
return View(appdata);
}
ApplicationCommentType
public class ApplicationCommentType
{
public IEnumerable<CommentType> CommentTypeData { get; set; }
public String CommentTypeDataSelection { get; set; }
public String Name { get; set; }
public String Email { get; set; }
public String Comment { get; set; }
}
CommentType
public partial class CommentType
{
public int CommentTypeID { get; set; }
public string CommentTypeDesc { get; set; }
}
<<p> 视图/strong> @using(@Html.BeginForm("Contact", "Home", FormMethod.Post, new{ @class ="form-horizontal"})){
<fieldset>
<legend>Contact Us</legend>
<div class="form-group">
@Html.LabelFor(x => x.Email, new {@class="col-lg-2 control-label"})
<div class="col-lg-10">
@Html.TextBoxFor(x => x.Email, new { @class = "form-control" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(x => x.Name, new { @class = "col-lg-2 control-label" })
<div class="col-lg-10">
@Html.TextBoxFor(x => x.Name, new { @class = "form-control" })
</div>
</div>
<div class="form-group">
<label for="textArea" class="col-lg-2 control-label">Questions, Comments, or Concerns</label>
<div class="col-lg-10">
@Html.TextAreaFor(x => x.Comment, new { @class = "form-control" })
</div>
</div>
<div class="form-group">
<label class="col-lg-2 control-label">Comment Type</label>
<div class="col-lg-10">
@foreach (var item in Model.CommentTypeData)
{
<div class="radio">
<label>
@Html.RadioButtonFor(x => x.CommentTypeData, item.CommentTypeDesc)
@Html.LabelFor(m => m.CommentTypeData, item.CommentTypeDesc, item.CommentTypeID)
</label>
</div>
}
@Html.HiddenFor(x => x.CommentTypeDataSelection)
</div>
</div>
</fieldset>
}
这样就可以了,所有的文本框项都可以工作了。在[HttpPost]
返回上放置一个断点将产生以下值。
Comment: "awesome"
CommentTypeData: Count = 0
CommentTypeDataSelection: null
Email: "example@example.com"
Name: "John Smith"
CommentTypeData不应该有计数吗?如果我检查请求,选中的值就在那里。
Request.Params["CommentTypeData"]: "General Improvement Suggestion"
那么为什么模型没有更新呢?是否需要从Request对象手动更新Model ?
你可以使用@Html。但是你应该确保项。CommentTypeDesc兼容Radio类型
参考MVC4:单个布尔模型属性的两个单选按钮
希望能有所帮助。
