使用多个编辑表单我想使多个编辑页面。 但我不知道如何在foreach
循环使用TextBoxFor()
,TextAreaFor()
,ValidationMessageFor()
。如何使用HTML帮助
@foreach (var note in Model.noteList)
{
using(Html.BeginForm()){
@Html.Hidden("id", note.id);
<div class="userIdArea"><b>@note.userId</b></div>
<div class="noteArea">@note.content</div>
<br />
<div class="editor-label">
@Html.LabelFor(model => model.note.userId)
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.note.userId, new { @Value = note.userId })
@Html.ValidationMessageFor(model => model.note.userId)
</div>
<div class="editor-field">
@Html.TextAreaFor(note => note.noteList)
@Html.ValidationMessageFor(model => model.note.content)
</div>
<input type="submit" value="Edit" />
}
}
上面的代码无法设置textarea的值,我不认为这是正确的方式来做到这一点。
EDIT)
我改变了这样的代码,
@foreach (var note in Model.noteList)
{
using(Html.BeginForm()){
@Html.Hidden("note.id", note.id);
<div class="userIdArea"><b>@note.userId</b></div>
<div class="noteArea">@note.content</div>
<br />
<div class="editor-label">
@Html.LabelFor(model => model.note.userId)
</div>
<div class="editor-field">
@Html.TextBoxFor(model => note.userId)
@Html.ValidationMessageFor(model => note.userId)
</div>
<div class="editor-field">
@Html.TextAreaFor(model => note.content)
@Html.ValidationMessageFor(_ => note.content)
</div>
<input type="submit" value="Edit" />
}
}
,我仍然有使用ValidationMessageFor问题()。
我只作一个内容为空,并提交形式,然后就发生这样的,
应该怎么办把ValidationMessage在正确的地方?
[编辑#2]
是的,我有太多的相同视图中创建的形式,
查看代码是这样的,
@model MemoBoard.Models.NoteViewModel
@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Note</h2>
<br /><br />
@using(Html.BeginForm()){
<div class="editor-label">
@Html.LabelFor(model => model.note.userId)
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.note.userId)
@Html.ValidationMessageFor(model => model.note.userId)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.note.content)
</div>
<div class="editor-field">
@Html.TextAreaFor(model => model.note.content, new { rows = 4})
@Html.ValidationMessageFor(model => model.note.content)
</div>
<input type="submit" value ="Save" />
} @* //End create form *@
<!-- List Area -->
@foreach (var note in Model.noteList)
{
using(Html.BeginForm()){
@Html.Hidden("note.id", note.id);
@Html.EditorForModel()
<div class="userIdArea"><b>@note.userId</b></div>
<div class="noteArea">@note.content</div>
<br />
<div class="editor-label">
@Html.LabelFor(model => model.note.userId)
</div>
<div class="editor-field">
@Html.EditorFor(model => note.userId, new { id = "A"})
@Html.ValidationMessageFor(model => note.userId)
</div>
<div class="editor-field">
@Html.TextAreaFor(model => note.content)
@Html.ValidationMessageFor(model => note.content)
</div>
<input type="submit" value="Edit" />
}
}
而且,
型号,
public class Note
{
[Key]
public int id { get; set; }
[Required(ErrorMessage="Content is required")]
[DisplayName("Note")]
public string content { get; set; }
public DateTime date { get; set; }
[Required(ErrorMessage = "User ID is required")]
[DisplayName("User ID")]
public string userId {get; set;}
public Boolean isPrivate { get; set; }
public virtual ICollection<AttachedFile> AttachedFiles { get; set; }
}
视图模型,
public class NoteViewModel
{
public IEnumerable<Note> noteList { get; set; }
public Note note { get; set; }
}
控制器,
public ActionResult Index()
{
var notes = unitOfWork.NoteRepository.GetNotes();
return View(new NoteViewModel(){noteList=notes.ToList(), note = new Note()});
}
[HttpPost]
public ActionResult Index(Note note)
{
try
{
if (ModelState.IsValid)
{
unitOfWork.NoteRepository.InsertNote(note);
unitOfWork.Save();
return RedirectToAction("Index");
}
}catch(DataException){
ModelState.AddModelError("", "Unable to save changes. Try again please");
}
var notes = unitOfWork.NoteRepository.GetNotes();
return View(new NoteViewModel() { noteList = notes.ToList(), note = new Note() });
}
感谢您的回答,请您再次查看我编辑过的问题吗?验证消息仍然存在问题。 –
我试过了我的自我,但对我来说它工作= /你必须有一些我们没有看到的其他代码,例如你有一个*保存*按钮和*编辑*按钮,但你的代码在问题中只有*编辑*按钮。 –
我用完整的代码再次编辑了我的问题,请您再次查看我已编辑的(#2)问题吗?对不起,再次要求..谢谢 –
