I've scenario where I want to insert data into database without post back. there are around 12 to 13 fields which i need to insert. I'm passing DTO from the client side which is actually Json object. Now the problem which i'm facing is how to convert that Json object which i got in webservice to the "class" (in my case class name is User) object.
[Code]....
In the above case AddNewUser method takes the object of User class. But i'm getting casting error. So how do I convert Json object to the "User" class object?
Is there an easy way to populate my C# Object with the JSON object passed via AJAX?
//This is the JSON Object passed to C# WEBMETHOD from the page using JSON.stringify
{"user":{"name":"asdf","teamname":"b","email":"c","players":["1","2"]}}
//C# WebMetod That receives the JSON Object
[WebMethod]
public static void SaveTeam(Object user)
{
}
//C# Class that represents the object structure of JSON Object passed in to the WebMethod
public class User
{
public string name { get; set; }
public string teamname { get; set; }
public string email { get; set; }
public Array players { get; set; }
}
I have a zmags catalogue program running in an IFrame, and are using the shopping capabilities to send data from the zmags viewer to a specified URL where I want to catch the data. The data is specified as XML data and stored in a "ShoppingList" POST variable. I then need to extract those data from the xml and send them as POST parameters yet again to another URL because the shopping system I'm using requires a specific parameterlist to fill the shoppingbag rather than an xml file. And I suppose I only need the ID and quantity since the rest is already part of the shopping system. In short what I'm looking for is:
catalogue --> *XML in POST variable* --> ASPX / ASCX / VB / C# (solution) --> *new URL call with new POST variables* --> SHOP aspx
I've been searching all day for a solution to this problem with small advances but no real solution. I hope this forum can provide some precise help, since I've been reading a lot of posts which answer different issues. I can't change the XML format or the fact that I need to send the data inside the XML as parameters to a new URL. I'm primarily working in ASP.NET and C# or VB for codebehind. XML data example

I have two model classes:
public class UserModel
{
public Guid Id { get; set; }
public string EmailAddress { get; set; }
public string LoginName { get; set; }
public string Password { get; set; }
}
public class GroupModel
{
public Guid Id { get; set; }
public string Name { get; set; }
public List<UserModel> Users { get; set; }
}
I created a View (Create.Aspx) by inheriting GroupModel class.

It is generating only two fields (Id, Name) in my aspx view. Also I am able to get the form data in the Model class object in ё[HttpPost]ё request which contains the data for ID and NAME field in controller.
[HttpPost]
public ActionResult Create(GroupModel groupModel)
{
try
{
// TODO: Add insert logic here
return RedirectToAction("Index");
}
catch
{
return View();
}
}
How can I get the data in List<UserModel> object? I am thinking to Put a List control with checkboxes containing Users. Then catch them using FormCollection object in controller.
I know how to retrieve a GET object with Request.Querystring("objname"), but how do I receive POST variables using the Request object, or somehow through the code?
View 2 RepliesWorking through the tutorial http://www.asp.net/mvc/tutorials/iteration-1-create-the-application-vbI am unable to delete anything as that method is not passing an object to the Delete POST function.Or more specifically, the object is nothing.Stepping through the GET method I get a bizzare 'There is no code after this point' after Return View(objectToDelete)The LINQ query for the GET method is the same as that for the Edit method but that is working fine.

I am using ASP.Net MVC2 and LINQ to SQL. I am using DataAnnotations and model binding in conjunction with a Form/View and its working beautifully well. Loving that.. My view is an "Add new Employee" form that's adding a new "Employee" complex object. Every Employee also has a child complex object called an "Address".
I am using the bound Html helpers in the view, such as Html.TextBoxFor(model => model.NewEmployee.FirstName) for example. Working beautifully well, validating beautifully well both client and server and coming into the controller fully populated and ready to be saved! Exciting.. ModelState.IsValid returns true and I go to save the new Employee.
The Employee is created fine but the system also creates a blank/new Address record in my Addresses table even when the Address fields are blank! How can I prevent any Address from being created, in situations where I ONLY want to create a new Employee with no Address. An example is when the user supplies an existing Address, then I wish to simply set the new Employee's AddressID to that of an existing physical address (I hope that makes sense). But it could apply to any situation where you need to create a new complex object, but you don't wish for LINQ to create any of its child complex objects. I have tried setting NewEmployee.Address = null after it is received in the controller, but even after that, a blank/new Address is still created. Even if I try NewEmployee.Address = SomeExistingAddress, it does correctly link the Employee to the existing Address, but it STILL goes off and creates another redundant new/blank address record! Which is really weird..
I have a "Create New Employee" ASP.Net MVC form. My complex object is an Employee and an Employee has an Address, which is another Complex object. On my View/Form I collect all required values for both the Employee and the Address. I'm using the bound HTML helpers such as: Html.TextBoxFor(model => model.EmployeeAddress.StreetName)
AND
Html.TextBoxFor(model => model.NewEmployee.FirstName)
This is all working beautifully well. Model binding is working like a dream, both server side and client side validation using DataAnnotations is working beautifully well and I am nicely receiving my populated complex objects as expected in the Controller.. Now I'm trying to save.. The Employee should always be newly created, because its an "Add New Employee" form. But sometimes the Address is an existing Address and I don't want to insert another one. Rather, I just want to link the Employee to the existing AddressID of the one that already exists in the database.
So I wrote a nifty GetExistingOrCreateNewAddress(Address PostedAddress) method which works great so I end up with the correct Address to use and link to the about to be saved Employee object. This is all happening in the same DataContext, so no problems there..
BUT even when I link the about to be saved Employee object to an existing Address, on save a new/empty Address row is created in my Addresses table. Even though the newly created Employee does link correctly to the existing Address I told it to! Why is it so??? And how can I save the new Employee without LINQ automatically creating a blank Address for me. Because I'm explicitly specifying an existing Address it should be linked to instead!
[HttpPost]
public ActionResult CreateEmployee(EmployeeDetailsViewModel NewEmployeeDetails)
{
if (ModelState.IsValid)
{
EmployeeRepository ER = new EmployeeeRepository();
// Fetch or Create the appropriate Address object for what has been entered
Address ActualAddress = ER.GetExistingOrCreateNewAddress(NewEmployeeDetails.EnteredAddress);
// Link this Address to the "about to be saved" Employee
NewEmployeeDetails.Employee.Address = ActualAddress;
// Lock it in..
ER.SaveNewEmployee(NewEmployeeDetails.Employee);

I have a column (data type timestamp) in SQL Server 2008.Now I want to show this timestamp value in ASP.Net C# app as string.

View 3 RepliesHow can i find what are the URL's opened in the browser window and how can i get that page as a page object as described below.
Eg:
The opened url ='http:\localhostIPTrackingIndex.aspx'
We can fetch the page by giving the below code
page=(page)HttpContext.Current.CurrentHandler.
How can we do it for all the opened URL's because if we give the HttpContext.Current.CurrentHandler then it will display the page object within the site but i want the page object from other sites also.
