You can use JSON.stringify when you posting data to pass arry of objects to controller.
$.ajax(
{
url: 'controller/CreateRecords',
data: JSON.stringify({MarksEntry: MarksEntry}),
contentType: 'application/json',
dataType: 'json',
type: 'POST',
success: function (data) {
// success
},
error: function () {
// error
}
});
Please refer following post for more information.

I want to deserialize a JSON coming from a web service, but for some reason I am getting an exception. I searched every question related to this topic but I did not find anything related to this exception. What might me the problem? here is the exception:
Newtonsoft.Json.JsonSerializationException: 'Unexpected token while deserializing object: EndObject. Path '', line 1, position 243.'
Here is my deserialize method:
public async Task<LoginApiResponse> AuthenticateUserAsync(string username, string password)
{
// try
// {
LoginApiRequest loginRequest = new LoginApiRequest()
{
Username = username,
Password = password
};
// serialize object to json
var content = new StringContent(JsonConvert.SerializeObject(loginRequest), Encoding.UTF8, "application/json");
var response = await Client.PostAsync(Constants.LOGIN_URI, content);
response.EnsureSuccessStatusCode();
// get the data on success and serialize it from json
using (var stream = await response.Content.ReadAsStreamAsync())
using (var reader = new StreamReader(stream))
using (var json = new JsonTextReader(reader))
{
System.Diagnostics.Debug.Write(">>>>>>>>>>>>>>>>>>>> " + Serializer.Deserialize<LoginApiResponse>(json));
return Serializer.Deserialize<LoginApiResponse>(json);
}
// }
/* catch (Exception ex)
{
return null;
}*/
}
here is the Request model:
public class LoginApiRequest
{
[JsonProperty("Username")]
public string Username { get; set; }
[JsonProperty("Password")]
public string Password { get; set; }
public LoginApiRequest() { }
}
here is the Response Model:
public class LoginApiResponse : MessageStatus
{
[JsonProperty("Data")]
public User Data { get; set; }
public LoginApiResponse() { }
}
here is the User model:
public class User
{
[JsonProperty("Address")]
public string Address { get; set; }
[JsonProperty("BloodType")]
public string BloodType { get; set; }
[JsonProperty("ConfirmPassword")]
public string ConfirmPassword { get; set; }
[JsonProperty("CustomerID")]
public string CustomerID { get; set; }
[JsonProperty("DOB")]
public string DOB { get; set; }
[JsonProperty("Email")]
public string Email { get; set; }
[JsonProperty("ID")]
public int? ID { get; set; }
[JsonProperty("IsActive")]
public bool IsActive { get; set; }
[JsonProperty("Name")]
public string Name { get; set; }
[JsonProperty("Password")]
public string Password { get; set; }
[JsonProperty("Phone")]
public string Phone { get; set; }
[JsonProperty("UserRoleID")]
public int? UserRoleID { get; set; }
[JsonProperty("Username")]
public string Username { get; set; }
public User() { }
}
and here is the the messagestatus:
public class MessageStatus
{
[JsonProperty("Message")]
public string Message { get; set; }
[JsonProperty("Status")]
public int Status { get; set; }
public MessageStatus() { }
}
and finally here is the json:
{
"Message": null,
"Status": 1,
"Data": {
"Address": "Beirut",
"BloodType": null,
"ConfirmPassword": null,
"CustomerID": null,
"DOB": null,

"Name": "tg",
"Password": "123456",
"Phone": "03708424",
"UserRoleID": 1,
"Username": "tg"
}
}
instead of
using (var stream = await response.Content.ReadAsStreamAsync())
using (var reader = new StreamReader(stream))
using (var json = new JsonTextReader(reader))
{
System.Diagnostics.Debug.Write(">>>>>>>>>>>>>>>>>>>> " + Serializer.Deserialize<LoginApiResponse>(json));
return Serializer.Deserialize<LoginApiResponse>(json);
}
try
var json = await response.Content.ReadAsStringAsync();
var data = JsonConvert.DeserializeObject<LoginApiResponse>(json)

I want to create multiple grouped Radio buttons. So, basically I have multiple questions and 3 radio buttons with answers. The problem I'm facing is how to return the selected value for the multiple radio buttons.
Controller

dbConnection.Open();
var questions = dbConnection.Query<QuestionsViewModel>("SELECT * FROM SOCQuestions ORDER BY soc_order_id");
var observationType = new List<ObservationType>
{
new ObservationType { Id = 1, Name = "Safe" },
new ObservationType { Id = 2, Name = "At Risk" },
new ObservationType { Id = 3, Name = "N/A" }
};
var rb = new List<Answer>();
foreach (var item in questions)
{
rb.Add(new Answer { Id = item.soc_question_id, ObservationTypes = observationType });
};
form.Answers = rb;
form.Questions = questions.ToList();
return View(form);
}
}

How to preserve the selected value after postback for that dropdownlist?
I have used two dropdown lists in my application. I need to search the gridview data based on the selected values of dropdownlist. The searched data is displayed in the pagedlist format. But when i move to next page of pagedlist, its displaying the whole grid view data rather than searched data. so any help will be appreciated.

Okey so i'm trying to update information in my database from a form.
But when i call db.SaveShanges() i get KeyNotFoundException.
I'm using MVC3 and EF 4.1.

I have checked the variables in debugger and it all seems to be ok.
I'm using MySql connector v6.5.4.
So anyone got any ideas what the problem might be?
After some days of frustration and searching i found the problem.
I used a custom made equals method in my UserInformation and Address class. That caused the problems. Now i have removed it and changed my Unit Tests to work in another way.
