我有一个带有checkBoxOption的注册视图
<div class="form-group">
@Html.Label("Whice Console You Play?")
@for (int i = 0; i < Model.ConsolesCheckBoxList.Count; i++)
{
@Html.CheckBoxFor(m => Model.ConsolesCheckBoxList[i].IsChecked)
@Html.HiddenFor(m => Model.ConsolesCheckBoxList[i].ConsoleId)
@Html.DisplayFor(m => Model.ConsolesCheckBoxList[i].ConsoleName)
}
</div>
当这种形式的输入之一不正确或未插入时，将显示ValidationMessageFor并重新显示视图，然后取消复选框的值，为什么？
这是控制器的代码：
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register([Bind(Exclude = "UserPhoto")]CommenModel model)
{
if (ModelState.IsValid)
{
// To convert the user uploaded Photo as Byte Array before save to DB
byte[] imageData = null;
if (Request.Files.Count > 0)
{
HttpPostedFileBase poImgFile = Request.Files["UserPhoto"];
using (var binary = new BinaryReader(poImgFile.InputStream))
{
imageData = binary.ReadBytes(poImgFile.ContentLength);
}
}
var user = new ApplicationUser
{
UserName = model.registerViewModel.Email,
Email = model.registerViewModel.Email,
Phone = model.registerViewModel.Phone
};
user.UserPhoto = imageData;
var result = await UserManager.CreateAsync(user, model.registerViewModel.Password);
//after the user create, we will use the id and add the id to the userAddress table include
// Address, langitud and latitude.
using (ApplicationDbContext dbo = new ApplicationDbContext())
{
var currentUserId = user.Id;
var pasinfo = dbo.userAddress.FirstOrDefault(d => d.Userid == currentUserId);
if (pasinfo == null)
{
pasinfo = dbo.userAddress.Create();
pasinfo.Userid = currentUserId;
dbo.userAddress.Add(pasinfo);
}
pasinfo.Address = model.useraddress.Address;
pasinfo.latitude = model.useraddress.latitude;
pasinfo.longitude = model.useraddress.longitude;
dbo.SaveChanges();
// now we used foreach loop to check which box is set to true on the view, and if the box set to true
// we take the id of the boxname and save it in conoleid.
foreach (var item in model.ConsolesCheckBoxList.Where(x => x.IsChecked).Select(x => x.ConsoleId))
{
var consoleid = item;
//here we create a new consoleuserInfo to insert data.
var consoleUserInfo = new ConsoleUserInfo
{
//we insert the id of user, and the consoleid of the checkbox how been marked.
Userid = currentUserId,
ConsoleId = consoleid
};
dbo.consoleUserInfo.Add(consoleUserInfo);
}
dbo.SaveChanges();
}
if (result.Succeeded)
{
// await SignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false);
// Send an email with this link
string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>");
return RedirectToAction("Index", "Home");
}
AddErrors(result);
}
// If we got this far, something failed, redisplay form
return View(model);
}
这是我在控制器上的视图：
// GET: /Account/Register
[AllowAnonymous]
public ActionResult Register()
{
//using database
using (ApplicationDbContext dbo = new ApplicationDbContext())
{
//data will save list of the consoleCheckBoxItem
var data = dbo.consolesCheckBox.ToList();
// because the view is request a common model, we will create new one
CommenModel a = new CommenModel();
a.ConsolesCheckBoxList = data;
// we will need to return common model, that way we will returen a
return View(a);
}
}
