My query is that i have data from database in datatable .

DataTable dt = OBJ.Fetch_PartDetails();

in dt i have all the records .Now i add all the records in list as

List list = new List();

for(int i=0;i

//foreach(var item in dt.Rows)

{

SecretaryUserModel GetAll = new SecretaryUserModel();

GetAll.TransactionDate = dt.Rows[i]["TransactionDate"].ToString();

GetAll.SLNo = Convert.ToInt32(dt.Rows[i]["SLNO"]);

GetAll.Particular = Convert.ToString(dt.Rows[i]["Particular"]);

GetAll.Balance = Convert.ToDecimal(dt.Rows[i]["Balance"]);

GetAll.Credit_Expenses = Convert.ToDecimal(dt.Rows[i]["Credit_Expenses"]);

GetAll.Debit_Expenses = Convert.ToDecimal(dt.Rows[i]["Debit_Expenses"]);

list.Add(GetAll);

}

and finally i send list to the view.

In top of the view page i declared it as

@model IEnumerable

but when i call the object of SecretaryUserModel the error come to me as

ienumerabledoes not contain a definition for fromdate and no extension........

Hi
you are trying to send a list in your model. but the model in your not having list. so just add a lit like List<SecretaryUserModel> in your your view model call and then use

Unfortunately, I am not a MVC expert, but the way I understand it, you can pass only one object as a model. This means, you will need to construct a container class which will have all required classes as properties and then send instance of that class.
So, suppose you want to pass 2 dates, 1 list, etc. Create one class
class ContainerClass
{
public datetime
public datetime
public List
}
and then have
@model ContainerClass
One thing is clear, whatever you are trying to pass, doesn't have FromDate ToDate properties, etc.
Hope you understand.

var particularsdetails = OBJ.Fetch_PartDetails().AsEnumerable().ToList().FirstOrDefault();
DataTable dt = OBJ.Fetch_PartDetails();
// List list = new List();
List listmodel = new List();
SecretaryUserModel GetAll = new SecretaryUserModel();
listmodel = (from DataRow row in dt.Rows
select new SecretaryUserModel
{
SLNo = Convert.ToInt32(row["SLNO"]),
TransactionDate = Convert.ToString(row["TransactionDate"]),
Particular = Convert.ToString(row["Particular"]),
Debit_Expenses = Convert.ToDecimal(row["Debit_Expenses"]),
Credit_Expenses=Convert.ToDecimal(row["Credit_Expenses"]),
Balance=Convert.ToDecimal(row["Balance"])
}).ToList();
now i return listmodel into view page and in view page at top i
write as
@model ServiceCatalogue.UI.Areas.BMS.Models.SecretaryUserModel
@{
ViewBag.Title = "Index";
Layout = "~/Areas/BMS/Views/Shared/_CareTakerLayoutPage.cshtml";
int i = 0;
}

To me it means, it is expecting a single instance of
ServiceCatalogue.UI.Areas.BMS.Models.SecretaryUserModel
but you are sending a List of it.
Hope it helps!

The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[ServiceCatalogue.UI.Areas.BMS.Models.SecretaryUserModel]', but this dictionary requires a model item of type 'ServiceCatalogue.UI.Areas.BMS.Models.SecretaryUserModel'.

Hello,
I don't think I fully understand this but this has nothing to do with IEnumerable.
Does your SecretaryUserModel has a FromDate property?
Also, in last line you mention SecretaryModel is this different than SecretaryUserModel?
