In my controller this code:
[HttpPost]
public ActionResult Edit(Company company, FormCollection IsCostCenters)
{
if (ModelState.IsValid)
{
Company objNewCompany = new Company();
//oParty.CostCenters.Clear();
using (PaymentAdviceEntityContainer db1 = new PaymentAdviceEntityContainer())
{
objNewCompany = db1.Companies.Find(company.Id);
objNewCompany.CostCenters.Clear();
string[] temp = IsCostCenters["CostCenters"].Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);
foreach (var s in temp)
{
if (s != "false")
{
CostCenter oCostCenter = new CostCenter();
oCostCenter = db1.CostCenters.Find(Convert.ToInt32(s));
objNewCompany.CostCenters.Add(oCostCenter);
}
}
db1.SaveChanges();
}
db.Entry(company).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
ViewBag.CreatedById = new SelectList(db.Employees, "Id", "FirstName", company.CreatedById);
return View(company);
}
And my view code as below
@using PaymentAdviceEntity;
@{
ViewBag.Title = "Edit";
List<CostCenter> clist = new List<CostCenter>();
clist = ((List<CostCenter>)ViewBag.CostCenters).ToList();
}
<div style="line-height: 22px; width: 100%;height :3%; float: left; ">
@{
foreach (var item in clist)
{
<div style="line-height: 22px; width: 28%; float: left;">
<span class="checkbox">@Html.CheckBox("CostCenters", item.IsChecked, new { @value = item.Id })</span>
<span>@Html.DisplayFor(modelItem => item.Name)</span>
</div>
}
}
So please what is reason ModelState.IsValid is return false in page post time ...

Please post your Model Class.
To check the errors in your ModelState use the following code:
var errors = ModelState
.Where(x => x.Value.Errors.Count > 0)
.Select(x => new { x.Key, x.Value.Errors })
.ToArray();
OR: You can also use
var errors = ModelState.Values.SelectMany(v => v.Errors);
Place a break point at the above line and see what are the errors in your ModelState.
As Brad Wilson states in his answer here:
ModelState.IsValid tells you if any model errors have been added to ModelState.
The default model binder will add some errors for basic type conversion issues (for example, passing a non-number for something which is an "int"). You can populate ModelState more fully based on whatever validation system you're using.
Try using :-
if (!ModelState.IsValid)
{
var errors = ModelState.SelectMany(x => x.Value.Errors.Select(z => z.Exception));
// Breakpoint, Log or examine the list with Exceptions.
}
If it helps catching you the error. Courtesy this and this
"ModelState.IsValid" tells you that the model is consumed by the view (i.e. PaymentAdviceEntity) is satisfy all types of validation or not specified in the model properties by DataAnotation.
In this code the view does not bind any model properties. So if you put any DataAnotations or validation in model (i.e. PaymentAdviceEntity). then the validations are not satisfy. say if any properties in model is Name which makes required in model.Then the value of the property remains blank after post.So the model is not valid (i.e. ModelState.IsValid returns false). You need to remove the model level validations.
