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.
Questions:
1. Was this code change really necessary?
2. Is there a better way to do it?

DbClick the code behind file of NerdDiner.edmx,It reads "This code was generated from a template." on the top comment lines. I generate my own .edmx file automatically with VS2010, just found that the .designer.cs file didnt contains Objectset,Methods as nerddinner does IDK which template hanselman used to generate this .edmx files，dont tell me he wrote it all by himself! Shoud .edmx and its code behind file be generated automaticlly without hard-coding?
View 4 RepliesI have uploaded the nerddinner sample to "www.aaa.com/test/nerd". When a mouse is on menu tab such as "Find a host" then the link is shown at the bottom of Internet explorer as "www.aaa.com/test/nerd/Dinner" with the contoller name "Dinner". When the mouse is on the main logo which is on top and left, the link shown as "www.aaa.com". So it direct me to "www.aaa.com" instead of "www.aaa.com/test/nerd"
When can I change it? I have tried change the "start url" from the application property, but it did not work.
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?

I am working on a website similar to nerddinner. Is it possible to perform similar join
using Linq to entities what is done with linq to sql in nerddinner.I am posting the codes below.
public IQueryable<Dinner> FindByLocation(float latitude, float longitude) {
var dinners = from dinner in FindUpcomingDinners()
join i in db.NearestDinners(latitude, longitude)

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!
I created a repository, just the way it was done in nerddinner but i cnt seem to get any intellisense on the word "db'..the code is below;

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.
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 asp.net, 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):
[code]....
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?
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:

View 2 RepliesI have an ASP.NET 4 site that uses the new SQL CE 4 CTP. The site works fine locally (IIS 7.5 on Win7) and fine in Server 2003/IIS 6. It fails when deploying to IIS 7 on Server 2008. The error I get is:
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
The interesting thing is if I switch the app pool user from its default user to LocalSystem, everything works great. So clearly there is a permissions problem somewhere.
Long story short, does anyone know what special permissions need to be set when deploying a SQL CE 4 database? (BTW, we have already set r/w access on the db itself and on c:windows emp)

I have a member function that does not depend on any member variables of the class. (in my case the class is an ASP.Net Page)
The function is protected, I dont need it outside of this class. Its only purpose is to build an URL from an given object.
Should I make all my functions static if they dont depend on the class, even if they are not used outside of this class?

I like to ask your opinions about how much time (in hours/work-days) should be allocated to develop a website similar to the following (please take a look):

The website simply display products and have a form where users can submit an order. No online transaction is done. Products are divided in categories and sub-categories.
Please note that its a general question regarding any website having same size (no. of pages), technology etc. The example website is given only to clearify.

So my question is in the Application_Error method, do I need the try/catch block when trying to write to the database? I'm thinking I would in case something goes wrong with the connection, etc. - but is this really necessary? Also, what would I do in the catch block if there is an error? At that point I would be catching the error of logging an error which is confusing in its own right.
