I am new in ASP.MVC4 and I am facing with problem to pass object from view to controller: Let me explain my problem from beginning: My class which is used by is for example: UserAndRolesModel
public class UserAndRolesModel
{
public user User { get; set; }
public IEnumerable<UserAndRoles> AsignedRoles { get; set; }
}
As You can see class UserAndRolesModel persists of 2 objects: user and Enumerable
public class user
{
[HiddenInput(DisplayValue=false)]
public virtual int user_id { get; set; }
[Required(ErrorMessage = "Please provide name")]
[Display(Name = "Name")]
public virtual string user_name { get; set; }
[Display(Name = "Is active?")]
public virtual bool user_active { get; set; }
}
public class UserAndRoles
{
public string RoleName { get; set; }
public bool IsAssigned { get; set; }
}
My controller action is simple, it assign user to UserWithRoles.User and creates tempList with UserAndRoles objects.
public ActionResult Edit(int userid=0)
{
//object which will be passed to View
UserAndRolesModel UserWithRoles = new UserAndRolesModel();
//user
UserWithRoles.User = repoUsers.Users.FirstOrDefault(x => x.user_id == userid);
//roles
IList<UserAndRoles> tempList = new List<UserAndRoles>();
UserAndRoles temp1 = new UserAndRoles();
temp1.RoleName="Admin";
temp1.IsAssigned=true;
UserAndRoles temp2 = new UserAndRoles();
temp2.RoleName="User";
temp2.IsAssigned=false;
tempList.Add(temp1);
tempList.Add(temp2);
//assign tempList to model
UserWithRoles.AsignedRoles = tempList;
return View(UserWithRoles);
)
At this stage I am successfully passing to View:
UserWithRoles.User.user_id=1;
UserWithRoles.User.user_name="UserName1";
UserWithRoles.User.user_active=true;
UserWithRoles.AsignedRoles[1].RoleName = "Admin";
UserWithRoles.AsignedRoles[1].IsAssigned = true ;
UserWithRoles.AsignedRoles[2].RoleName = "User";
UserWithRoles.AsignedRoles[2].IsAssigned = false;
I am able to display above View properly:
@model Models.UserAndRolesModel
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)
<fieldset>
<div class="editor-field">
@Html.EditorFor(model => model.User.user_id)
@Html.ValidationMessageFor(model => model.User.user_id)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.User.user_name)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.User.user_name)
@Html.ValidationMessageFor(model => model.User.user_name)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.User.user_active)
</div>
<div class="editor-field">
@Html.CheckBoxFor(model => model.User.user_active)
@Html.ValidationMessageFor(model => model.User.user_active)
</div>
<br /> ROLES below is piece of code which makes me cry<br />
@foreach (var item in Model.AsignedRoles)
{
<div class="editor-field">
<div class="editor-field">
@Html.LabelFor(model => item.RoleName)
@Html.CheckBoxFor(model => item.IsAssigned)
</div>
</div>
}
<p>
<input type="submit" value="Save" />
</p>
</fieldset>
}
When i Click submit all data regarding user was passed properly but IEnumerable AsignedRoles is always null. Here is my controller method on post:
[HttpPost]
public ActionResult Edit(UserAndRolesModel UserWithRoles)
{
if (ModelState.IsValid)
{
if (UserWithRoles.AsignedRoles==null)
Console.WriteLine("I am still crying");
else
Console.WriteLine("Got it!");
}
return View(UserWithRoles);
}
In View I tried to use other loops for example:
@for (int i = 0; i < Model.AsignedRoles.Count(); i++)
{
<div class="editor-field">
@Html.LabelFor(model => item[i].IsAssigned)
@Html.CheckBoxFor(model => item[i].IsAssigned)
</div>
}
But above also does not pass IEnumerable. Can anyone help me to resolve this issue? How can I pass back to controller UserAndRolesModelwhich contains IEnumerable? I will be very grateful. Advance thanks for the help!
