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?

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.

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 :: Error When Adding To Listbox / Object Reference Not Set To An Instance Of An Object

Feb 19, 2010

I have just recently converted my VB code to C# and now having this error when I try to add an item to my listbox, and the value is coming from the item page. I get the error at this segement:

lstboxCart.Items.Add(cartItem.Display());

My listbox is supposed to add the product's name, quantity, and price onto one row.

Here's what I have so far:

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.

Web Forms :: Error Handling For Object Reference Not Set To An Instance Of An Object?

Aug 17, 2010

This might have been asked before but I did a quick search and found nothing.

Problem: I want to get the name of the object that has a value of nothing and the type of the object when the "Object reference not set to an instance of an object error" occurs. The type obviously can be Object or specific. I want this information so that I can log a better error message in the error handling module. The only real useful information currently that comes back from the Exception object on a try catch is the line number at which the error occurred which in most cases is adequate except when you have functions calling functions, all in one line.

It happens when I'm logged in to the website and i leave a page open for more then 5 minutes without doing anything.. I can't trace it because on debug mode it works fine.. First i thought it might be the session timeout but I've extended it to 60 minutes and still the same error.

VS 2010 - Object Reference Not Set To Instance Of Object Error On Linkbutton Click

Nov 8, 2012

I have 2 pages in my project (that are causing the problems). My default page has a FormView that for some reason will not let me access page events, such as buttons for instance, in code behind. They show up fine on page but are not visible in the page events drop down in code behind. We are using a work around for that.

The main issue now is that on my ViewTaxes.aspx page I need to get the values of some of the text boxes from the default page by Control Number, i.e. whatever record is being viewed on default page when you click the ViewTaxes link button, much more detailed information about that particular record is displayed on ViewTaxes. If on ViewTaxes I use a SELECT * statement I can access the ViewTaxes page when I click the button. We, of course, need to filter the data displayed by ControlNumber. When I add a WHERE clause to the DS on ViewTaxes page and click linkbutton on the default page I get an Object Reference error. This error seems to have something to do with a group of textboxes that are displayed via Session in codebehind. Values from default page being displayed in one section of ViewTaxes page. The error when thrown always points to Session("Owner1") = txtCust1.Text. If that code is removed then error will go to next Session variable, an so on.

I should also point out that both pages worked fine, no problems at all, using a test MySql table. We recently migrated the actual table that will be used from an Access database and replaced the test table. Can't find any spelling errors or anything of that nature. There are some Null fields in this database but it is set to allow Nulls.
