C# - How To Get A Reference To The Page Object In An Asmx It Calls
Feb 13, 2010
I have a page that calls on an asmx within the project (for some ajax stuff). Within that asmx I'm calculating a value and returning it to be output to the screen.
However I need to do a recalculation that includes summing this value with a few others. The function that performs the calculation is in a UserControl on the page.
How do I get a reference to the page object so I can use FindControl to get an instance of the user control so I can call that calcuation function?

I have a list of items on my page. There is a button in each row to edit that record. Record is being edited in jquery modal window. So I make an asynchronous call to server to display detail information about record without full page refresh.
User fills in data about that record and submits. If everything is ok, user is redirected back to page. But if validation fails I want to display that entry form again with errors.
If this call is done synchronously, users gets back form with filled data and errors, but without styles and javascript (because they are referenced from mail page) - that is ok
So I just wanted to refresh that modal dialog with asynchronous call. The problem is that Html.DropDownList or Html.TextBox extension methods fail with null reference exception. I have checked that real data are passed in as second parameter.
So I don`t understand where that null reference exception occurs, or what can I do?
The same call works if it is synchronous (Html.BeginForm) but fails if it is asynchronous (Ajax.BeginForm)
what can I do with it?

in my default.aspx page i have a dropdown List and a textbox with a submit button below that there are 2 listbox... and the dropdown list holds the names of the listbox
my logic here is to select an item from the dropdown list and put some text in the text box and submit the form which will add an item to the listbox selected.. but when i do this i get an error saying Object reference not set to an instance of an object. i tried to figure out the problem and found that when i remove the reference to the Site Master Page it works fine and when i undo and apply my reference back to the Site Master Page i get the same error.

I could really use some help on this one. I've been fighting it now for several days and we are supposed to start testing early next week.I am subscribing to 4 web services all hosted by the same company. The integration with 1, 2 and 3 all went fine, but on the fourth I keep getting the very unhelpful error:
System.Web.Services.Protocols.SoapException = {"Server was unable to process request. ---> Object reference not set to an instance of an object."}

I'm new to programming in ASP.NET, but I'm making my way through Wrox's Beginning ASP.NET 3.5 in C# and VB.NET.
I'm at a section where I'm creating a BasePage. I successfully created a BasePage by creating a new class file in my App_Code folder called BasePage.cs with the following code:
[Code]....
If I run that code everything works out fine. The page loads and all is well. But, if I try to do the same thing to a page that uses my MasterPage.master file, I get the following error:
Object reference not set to an instance of an object.
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Why is that? In the example code from the book (that also uses a MasterPage.master file), everything excutes and runs just fine. But in my test, I get the above error. I've tried comparing my pages to the books included source pages, but I can't find any differences.

I'm using IIS 6 on a Windows 2003 Server and I am trying to get an MVC2 project installed on that machine. I am having nightmare-ish problems doing so!I've looked up TONS of references on what to do, and not 1 single one works. (They work for MVC1 projects, as I have a few of those running already using said solutions).
I have tried it on 2 of my dev servers, and both get the same result. The closest I can get to a served page is an error page "Object reference not set to an instance of an object", however, the page has try/catch blocks that are being ignored, so I dont think its running the code on the controller, I think it's saying that the controller is the error. (For the reference, the error in question is directed at the HomeController.cs file).
What I've tried:
Wildcard mapping
Changing routes to {controller}.mvc
Changing routes to {controller}.aspx
Adding the .mvc extension to IIS
Modifying routes in Global.asax
There's a LOT of code in this project so far, so I will only post the first page(s) that should get served:
MASTER PAGE:
<div class="page">
<div id="header"> [code]....
I did not list the CreateUserSecurity method, but all it does it call the DB using the Username and returns the record in the database that matches the username.
EDIT: Added code and what I've tried so far (as requested).

I am developing a usercontrol, in this case a toolbar. Some of the buttons on the toolbar will interact with other objects on the page which are not part of the toolbar. (In this case a map) So the toolbar code behind wants to say something like this:
[code]....
My problem is that MyMap does not exist in the design environment of the usercontrol and therefore produces an error when it is referenced. So my question is, How is this typically handled? Can the usercontrol reference another control that does not exist within itself?

I am working on converting a project from C# to VB and am facing this weird issue. 1 page cannot compile and I get the reference error, but the weird thing is that the compiler shows the error as coming from ASP.NET generated code. Visual Studio shows me that error is coming from my ASPX page. I cannot seem to figure out why or where this error is occuring. Also if I take the inherits attribute out I don't get the compilation error. The code in aspx page is below:

I have a url like this:
http://www.somepage.com/main.aspx. In this page, when I click on a link it takes me to a page
http://www.somepage.com/cental.aspx?cid=200. So in the cental.aspx.cs page I did the following in the page load:
if(request.querystring["comp"].tostring() != null)
{
//do some thing [code].....
So I got an error like: object reference not set to an instance of reference.My problem is, I am using the same page. So when I go from some page, I will have "comp". but other times not. So when there is no "comp", how do I handle it in request.querystring?

I need to connect to a WebService provided by someone else. This WS (all https) has three methods that are accessible without having logged on:
login, logoff, getVersion . All other methods require that the login-method has been called before. Nothing special unto this point. However, the docs state that I have to make sure that (quote):
"All method calls between login and logoff are to be carried out by means of the same persistent http-connection (key word: http persistent connections or http connection reuse"
I seem to be unable to figure out how that would work - all WS'es I ever utilized were either taking user/pwd combinations in each method call or the login-method returned something like a SessionID which was then used for each subsequent call to a given method (i.e. passed as a parameter). If I call the login-method and subsequently call any method that requires authentication, the call will fail with an exception telling me that I need to log in first.

I am working on web application in which all of the data I am submitting back to the server is being done on the client side using JQuery AJAX calls to my .NET web services using JSON. This works perfectly to enhance my user experience and greatly reduces post backs, etc.What I am looking for suggestions on is securing the web services being exposed to the client side from being used by anything but my JQuery code on my site. The security hole that I see here is that since the client-side JQuery can access the web services, so could anything.

I can't seem to call a web service method from Ajax with both POST and GET.
Initially only the POST would work and GET would causes this error:
{"Message":"An attempt was made to call the method u0027getDatau0027 using a GET request, which is not allowed.","StackTrace":" at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext
context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}
I fixed that by adding this attribute: [ScriptMethod(UseHttpGet=true)] but now GET causes this error:
[code]....
So is it true that you can only use either POST or GET and not both from Ajax?

I have an XML web service where the authentication used is BASIC WINDOWS. Following is my client code to connect to the service.
[Code]....
Now, the issue is that the client is really authenticated only in the first attempt(First time I execute the code in VS). Further attempts succeed even if the code to assign credentials is commented or even after providing wrong user id/ password. I ensured that the server is hit each time(Just to make it clear that it not just because of client side caching).Is this the behavior of Basic authentication/credential cache. I would prefer the client be authenticated each time he hits the server.
