Web Forms :: Error When Using A BasePage Along With A Master Page/ Object Reference Not Set To An Instance Of An Object
Mar 6, 2010I'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.

View 1 RepliesError Page "Object Reference Not Set To An Instance Of An Object"?
Apr 8, 2010I'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).
How To Send The User To A Separate Page
Jun 11, 2010I have a view where I want to perform different actions on the items in each row in a table, similar to this (in, say, ~/Views/Thing/Manage.aspx):
[code]....
In the most part, this is working fine. The problem is that if ThingService.SetEnabled throws an error, I want to be able to display the error at the top of the table. I've tried a few things with Html.ValidationSummary() in the page but I can't get it to work.
Note that I don't want to send the user to a separate page to do this, and I'm trying to do it without using any javascript.

How To Create A Custom 404 Page And Send A 404 Msg
Jan 21, 2010I know how to redirect pages with Rewrite. But when there is a 404 page how would i display my own custom 404 page (i know i can rewrite it) and say this is in fact a 404 and not just a plain rewritten page?How i can SET the error code instead of asking the server? if the user goes to /user/invaliduser/ i would like to send a 403 or 404 but my rewrite would send it to a valid page to display user info so i would like to know how to say doesnt exist rather then empty fields in a page.
View 2 RepliesC# - Send An Array Of Strings From One Page To Another?
Jun 1, 2010I now have two asp.net pages. When I click on a link on page A, I open the other one (let's call it page B). When I do this, I want to send some information from Page A to Page B in the form of an array of strings. This array is different depending on what link I follow on Page A.
I know I could send this information via the URL with the ?string1=bla1&string2=bla2 etc., but I don't want it that way, as it can get complicated if there are too many strings in the array.
I think there is something similar, like a POST in PHP, but how would that be in ASP?
