MVC :: Change Needed To NerdDinner Mvc Example?

Mar 15, 2010

As I am working thru the NerdDinner MVC example. I found that after implementing step 6 that edits to a dinner were no longer saved. After some investigation I found that I needed to add the ValueProvider to the UpdateModel function call in Edit (HttpPost) example. My updated code is below.


1. Was this code change really necessary?

2. Is there a better way to do it?

MVC :: Nerddinner Using The Database From SQL EXPRESS Server

Mar 26, 2010

I have problem when I am working on the NerdDinner tutorial. If I create local database (in the project local) then it is working OK, but if I added connection with the database already existed in the SQL EXPRESS 2005 (using Data Connections -> Add Connection; from the Server Explored in the VS 2008) then I got GPF. Does anyone know how to use the database for server instead of local project?

MVC :: NerdDinner: Map / Ends Up On The Exact Same Coordinates On The Map Regardless Of The Address?

I started a website based on the NerdDinner source code, everything worked fine (more or less) but whenever I post an event, it ends up on the exact same coordinates on the map regardless of the address (Somewhere in the Gulf of Guinea!)

No idea what to do: I didn't alter the map code at all!

MVC :: 2 NerdDinner - Data No Longer Saves After Adding ViewModel

Sep 3, 2010

I am creating the NerdDinner application via the Professional ASP.NET MVC 2 book, and once I got to the ViewModel part (pages 88-91), I noticed none of my data was saving any longer. I discovered several errors and areas of confusion in these pages of the book, which I will list now.

Page 88: When it says to add the DinnerFormViewModel class, it doesn't say what folder to add it to. On page 89, the Inherits example (NerdDinner.Controllers.DinnerFormViewModel) implies it was added to the Controllers folder, but if that were so, the code on page 88 would need to use Models.Dinner instead of just Dinner. No big deal; just put it in Models and change the Inherit statement on page 89 to use NerdDinner.Models.DinnerFormViewModel.

Page 89: At the bottom of the page is some wrong code. Since the properties of Dinner are now one level deeper, all references to m.Title, m.Country, etc, need to be m.Dinner.Title, m.Dinner.Country, etc. The statements above the code are also incorrect ("Notice... we are not changing the names of the input elements... the form elements will still be named...") -- the form elements will actually change from "Title", "Country", etc to "Dinner_Title", "Dinner_Country", etc.

Page 90 (Code Snippet 1-53): This was the one that broke the data saving. Now that the form elements have prefixes, the TryUpdateModel(dinner) needs to pass a prefix, like TryUpdateModel(dinner, "Dinner"). This will append "Dinner_" to the element names so that they can be found on the form.

MVC :: NerdDinner Sample - How Does Delete Work - How To Control Deletes

Jun 7, 2010

I am still at the elementary stages of Linq To Sql and Entities usage. I started practicing MVC developement by following the NerdDinner tutorial here at, and I back myself up with fully developed NerdDinner sample (1.0 -- still on VS2008). I am also at the first half of the NerdDinner tutorial (I think -- maybe I'm further along) - so far I have gotten up to the Delete View. In the fully developed sample I noted that it uses ascx file (which I guess I will find out if the tutorial also will use
ascx files down the road). My sample app, which I am developing from the tutorial, seems to work OK so far. My issue is that I am not clear how the Delete mechanism works. In the DinnerRepository.cs I have this code (from the tutorial):


It looks like a dinner object is being passed to these mechanisms and the delete occurs based on a row ID value. But what if I wanted to delete multiple rows - say where ID between 15 and 20 - how to go about this? I was looking for a Delete statement but am not finding it either in what I have developed so far from my tutorial sample or from the fully developed sample. How can I control Deletes in MVC?

MVC :: Nerddinner Repository Dinner Edit Fails To Save?

Dec 10, 2010

I'm trying to use the Nerddinner as a model to built my own project. I'm using the repository method but I cannot fiqure out why the Edit does not save to the database. I tested in the Nerddinner and it failed to save as well. Is this not functional in Nerdinner or could it be due to me using VS 2010 express?

I also started using MVC3 so I thought that could be the problem. I did some testing and was able to get my Edit to update to the database if I have the controller access the database instead of the repository.

Here's the relevant code from NerdDinner:

State Management :: Error On Page And "Unknown Error - Code 0" In Error Message?

Dec 6, 2010

I have a serious problem with "Error on Page". The error message points to line number 939, char 13. In my code behind (C#) in line number 939 is only an obsolete method found which is no longer called. The aspx file has only 339 lines. What the heck is line number 939?The Webapplication allows a special user group to change some group memberships for members of another user group in Active Directory. The App handles 3internal DataViews derived from corresponding DataTables as DataSource for 3 GridViews and some other internal lists with objects (List<obj>).

It uses windows authentication to get current users credentials and his membership in the "Operators" group. This credentials will be passed-through to allow the process managing group memberships in active directory.After starting the App in browser it seems to work fine. But after an indeterminated time it doesn't longer respond. After each click on buttons (or link buttons) you only can see the message "Error on Page" in the browsers status bar below.I played with session timeout, storing the DataTables in session variables, without success.

Last week I found this article here: [URL]" and I addedEnableEventValidation="false" ViewStateEncryptionMode="Never"
to Page declaration. However, at some point the the server does not respond. Each time the worker process on webserver recycles it seems the application turn to wrong state. Might be important: All controls including GridViews are embedded in an AJAX UpdatePanel. How to get a better error message? Debugging is enabled and Custom Error handling On, Off or Remote Only brings the same result as described.

Configuration :: Error Handling - Crendentials To Send Email When Server Error Occurs?

Nov 14, 2010

When a server error occurs for whatever reasons (YSOD), the server will send a message via SMTP class. In my case, my company employs microsoft exchange and uses NTLM authentication for all domain users. I am authenticating users via NTLA windows integrated authentication. My question is, is it possible to utilize this authentication data, and pass it to the system.web SMTP username/password authentication scheme to send an email to me (the web developer) when the error occurs? I am pretty sure my company requires a username/pwd to send emails via SMPT on the ms exchange server.

Configuration :: Error With Writing To DB On Web Server. A Network-related Or Instance-specific Error

May 25, 2010

I am REALLY stuck with this and need a solution in the next 24 hours .i I have uploaded my web application to the web and have the database and connection strings functioning and reading the data from the database. But when I try to write to the DB

I get the following error :

Server Error in '/' Application.

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

(provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

The wierd thing about this is the connection strings work from the local machine when I run from Visual Studio and I can write to the DB there, I just cannot write to the DB from the URL.

I am pretty new to but I am sure it has to be something to do with the web.config.

Web Forms :: Session_Start Executes Again After An Error Occurs (when Going To Custom Error Page)

Mar 7, 2011

I'm having a wicked time trying to redirect the different error scenarios to a custom error page. Basically, I have put some code in Application_Error in global.asax, and done the necessary web.config settings to use Custom Errors.

In global.asax on Application_Error, I stored the Server.GetLastError in Session. The reason I have to store it in Session is because (as far as I know) you lose the exception when using "ResponseRedirect". And the reason I have to use ResponseRedirect is because I am using an UpdatePanel with AJAX calls, and any exception during the AJAX call shows up as a JavaScript error, and doesn't get handled using the custom error page (see this post).

void Application_Error(object sender, EventArgs e){ ////must perform this check to avoid the "Session state is not available in this context" errors if (HttpContext.Current.Session != null) { Session["LastException"] = Server.GetLastError(); } else { // (I think this happens when there are compile-time errors) Server.Transfer("~/Oops.aspx"); }}void Session_Start(object sender, EventArgs e){ //must perform this check to avoid the "Session state is not available in this context" errors if (HttpContext.Current.Session != null) { //initialize the session ( Session["LastException"] = ""; }}
