SQL Reporting :: Object Reference Not Set To An Instance Of An Object?

May 26, 2010

i am getting the noted error on various date columns (there are 33). In the aspx page is a textbox where the user can enter their name to retrieve the report, some drop downs for setting sort order, and a sqldatasource whose selectcommand is built when a button is clicked and the reportviewer is unhidden. For one person, the error occurs only for column 'A', where for another user it occurs on column 'B'. Not all rows have a date in any given column regardless of either user--but if i delete column 'A' for user 1, the report runs. If I delete column 'B' for user 2, the report runs. If the sort is changed, the column in error changes--even though its the same data being returned.

Web Forms :: Session Ended - But Server Error/ Object Reference Not Set To An Instance Of Object?

Nov 15, 2010

In the VS2005 environment, when I test my session to make sure the page redirects to the main page (itself) if the session is null, it works. There is no error.

The function I use for this is:

[code]....

However, when it is in the production environment in IIS 6.0, when the session has timed out, and I then do a postback by doing some slider control, I see the page reload but immediately thereafter, it throws a Server Error exception of : Object reference not set to an instance of object.

Looking at the stack trace, the event occured:

AJAXEnabledWebApplication1._Default.Slider1_TextChanged(Object sender, EventArgs e)

however, why is it that the Slider1_TextChanged event fired even even after during page_load, the page was told to do a response.direct ?? shouldn't the entire page have gone through a full-page refresh life cycle ? why did it continue on to attempt to raise the Slider1_TextChanged event?

Web Forms :: Error When Using A BasePage Along With A Master Page/ Object Reference Not Set To An Instance Of An Object

Mar 6, 2010

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.

Web Forms :: Unable To Read Web.config File/Object Reference Not Set To An Instance Of An Object

Nov 2, 2010

I have a website written in C# that was running fine on one server. We moved it to another server and have a couple issues. I am mainly a VB.NET coder but can do a few things in C#. This is not a project - it is a website and can open it in VS2008 no problem. This is an admin site for the whole website where the user can add customer comments, etc. When logging in, it works fine. I can go to one of the admin pages after logging in and works. If I go to two other different pages, I get this error:

Object reference not set to an instance of an object.

[Code]....

It turns out this is in the main.master page and it is used by the other pages that load fine. The ApplicationTitle variable is set right in the web.config file and like I said, it shows on the other pages.

My question is why would this code work fine for some pages and not two others? All of these admin pages are under a folder called Admin and the web.config file is in the root folder of the website. Its almost like these two pages cannot see the web.config file in the root folder? Why would that be if thats the case?

My guess is that the source of the problem could be in the foreach loop from my cart class, shouldn't I be using that for arrays only? If I need to post any markup code or any other class, let me know.
