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.

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?

I stucked at a condition , where i need to share values between the pages. I want to share value from Codebehind via little or no javascript. I already have a question here on SO , but using JS. Still did'nt got any result so another approach i am asking.
So I want to know can i pass any .net object in query string. SO that i can unbox it on other end conveniently.
Update
Or is there any JavaScript approach, by passing it to windows modal dialog. or something like that.
What I am doing
What i was doing is that on my parent page load. I am extracting the properties from my class that has values fetched from db. and put it in a Session["mySession"]. Some thing like this.
Session["mySession"] = myClass.myStatus which is List<int>;
Now on one my event that checkbox click event from client side, i am opening a popup. and on its page load, extracting the list and filling the checkbox list on the child page.
Now from here user can modify its selection and close this page. Close is done via a button called save , on which i am iterating through the checked items and again sending it in Session["mySession"].
But the problem is here , when ever i again click on radio button to view the updated values , it displays the previous one. That is , If my total count of list is 3 from the db, and after modification it is 1. After reopening it still displays 3 instead of 1.
I am doing a project in ASP.NET MVC in which I want to implement an IoC container. I am new to IoC containers and have been searching to find a solution to my problem, but so far to no avail.
The problem is dat data is distributed across various databases. Once a user is logged in, the database for the user is retrieved from an authorization database and then set in the user session. That user session is passed on to the services and repositories when they are constructed, so they can use it when they need it to access the database.
A typical bare stripped service (without interfaces and ioc) looks like this:
private CompetitionRepository _CompetitionRepo;
public CompetitionService(DataContext dataContext)
: this (new CompetitionRepository(dataContext))
{ }
[code]...
The "DataContext" contains a couple of properties with which the correct database is selected for the session. Because the Services and Repositories don't have access to the session itself (which is outside of their scope) they need this object.
I have a webform whose ObjectDataSource reads an xml file to populate a GridView in the .aspx page. I have to hard code the file path in the .cs file defining the ObjectDataSource classes. I want to be able to use a portion of the query string to indicate which file to select, but, normal methods, like Server.MapPath and Http.Request.Current don't work in the class page. how I can pass values from the SelectParameters configured in the ObjectDataSource down to the ObjectDataSource method?

I want to write a webservice, and in one of its methods, I want user to pass one my object's instance as parameter.

Consider the following data
<xml>
<id>10</id>
<value1>15<value1>
</xml>
I need to use this data as an input to ajax request. For eg. consider a dropdownlist change event, I need to pass these values to the controller.
sample code
//dropdown change event
$("#TestReqID").change(function() {
var id = 10;
var testResults = "abc";
var inXML = "<xml>";
inXML = inXML + "<id>" + id + "</id>";
inXML = inXML + "<value1>" + testResults + "</value1>";
inXML = inXML + "</xml>"
$.getJSON("/Home/UpdateTest/Json/" + inXML, function(data) {
//success code goes here
});
});
in HomeController
public ActionResult UpdateTest(string obj)
{
if (HttpContext.Request.IsAjaxRequest())
{
/*
Need to parse data in "obj" from ajax request
*/
IPTests test = _service.GetIPTest(Convert.ToInt32(id));
return new JsonResult { Data = new { ipTestId = "0", testResults = "" } };
}
return View(test);
}

I developed a C# web application that calls a web-service which returns a base64 encoded array (PDF file). I then convert that array into a UCOMIStream object (I know it is obsolete, but the DLL that I am using requires it as a parameter). I use the following code to do the conversion which works perfectly. I can pass this object to the DLL so that I can print the PDF.
This works great on the Webserver, but the requirement is to print it locally.
Byte[] bBuffer = statementOut.statementcycle.statementdata.content;
int size = bBuffer.Length;
IntPtr mem = Marshal.AllocHGlobal(size);
Marshal.Copy(bBuffer, 0, mem, size);
// Create an OLE Stream object.
System.Runtime.InteropServices.UCOMIStream str; //obsolete but the createstreamonhglobal outputs it
CreateStreamOnHGlobal(mem, true, out str);
The DLL resides on the client so I am able to use ActiveX to create the object using javascript and/or VBscript;however, I have not been able to figure out how to get the stream object to the client to pass to the DLL.
