MVC simple question

Posted By:      Posted Date: October 19, 2010    Points: 0   Category :ASP.Net

I am using this book http://www.wrox.com/WileyCDA/WroxTitle/Professional-ASP-NET-MVC-2.productCd-0470643188.html
I discuss with author Project call NerDinner

there is 2 table Dinners and RVSP stored some information

author tries to retrive information from Dinners table with this function whic is written in Model Folder Class DinnerRepository:
here is:

public class DinnerRepository {

      private NerdDinnerEntities entities=new NerdDinnerEntities();

      public IQueryable<Dinner> FindUpcomingDinners() {
          return from dinner in entities.Dinners
                     select dinner;

 public class DinnersController : Controller {
         DinnerRepository dinnerRepository= new DinnerRepository();

         public ActionResult Index() {
            var dinners = dinnerRepository.FindUpcomingDinners().ToList();
            return View("Index", dinners);

when I run this solution there is an error: The model item passed into the dictionary is of type 
'System.Collections.Generic.List`1[NerDinner.Models.Dinner]', but this 
dictionary requires a model item of type

Entity framework simple question




First I am newbie using EF - so sorry on this basic question


I have a Project Table that relate to Company Table


When I Map with EF I Do not have property of CompanyId in the Project Object

But I have related Company Object


For example

Project p = new Project();

p.CompanyId è does not exist!

When I try addingit myself I get this error:

If I need just the Company id, and I don't want get it like

p.Company.CompanyId - because than the application try connect again to the DB and I don't want this, because I need just the CompanyId.

What the best regular way to get it?


A simple Data Modeling Question


I have a data modeling question that hopefully this fictious example will help explain.  My application is data driven and the classes reflect the tables to a large degree.   In this example my database has two tables:

  • VendorMaster with an int Primary Key of VendorID
  • VendorContact with an int Primary Key of ContactID

The VendorContact table also has a Foreign Key of VendorID in order to associate the contact with a specific Vendor.  In this example a Vendor can only have one contact.

My question is how to represent these two tables in terms of classes.  In my current design I have two classes:

  • VendorMaster
  • VendorContact

In order to represent the relationship between a VendorMaster and VendorContact, my VendorMaster class contains a property called VendorContact.

My questions are about the VendorContact class and how it represents the relationship between a VendorMaster and itself.

Option #1

The VendorContact class should contain an int property of VendorID

Option #2

The VendorContact class should contain a VendorMaster Property

I am not sure which option is the 'best' option to take. My concern is that if I go with option #2 that I would create a cyclical relationship between the VendorMaster and Vendo

Simple data binding question

Newbie binding question here: is it possible to bind a control in XAML to a StaticResource by passing in the key via a data structure? Basically something like this: <TextBlock Text="{Binding ImageKey}" /> <Image Source="{StaticResource ResourceKey={Binding ImageKey}}" /> <-- doesn't work   The TextBlock binding on the first line works correctly, it extracts the key of the StaticResource from my data structure and displays it correctly. What I'm trying to do is get the Image control to bind to the StaticResource with that name (which happens to be a BitmapImage).

Simple but unusual SQL 2008 peer2peer replication concept and question

Hi, I am not an SQL expert, but have to set up 3 remote SQL databases that need to be synchronised with each other. This is unusual because the locations are tiny atolls in the middle of the Pacific.  Communication between them is by satellite only which has limited bandwidth and is expensive.  The total population (thats all the people) on each atoll is only 500.  There is likely to be a maximum of 40 potential users per atoll and each SQL database is for internet login authentication only (Radius).  So the databases are tiny and have a very low update rate. What is the simplest way to synchronise the databases?  Doing this just once each night at around 4:00am would be best.  Peer to peer replication sounded right, but I do not want our extremely limited bandwidth taken up by this traffic when all we need is for the databases to be synchronised by the next day.  Also we are running MS SQL 2008 R2 Workshop edition and I am reading that this does not support peer2peer replication. The hardware is a laptop - since hot moisture laden salty air is very corrosive for traditional servers and power is intermittant at best.  Each atoll gets an identical system. Can anyone suggest a solution or ideas?  I am happy yo answer questions.  Thank you.

Simple question about indexing

Hi, Let's say I have a table that looks like this: StudentID int, PK FirstName varchar(50) not null LastName varchar(50) not null Score tinyint not null My question is this: if I'll be using the "Score" column in my SELECT statements such as MAX(Score) or SCORE > 75, etc. do I need to create an index for the Score column? Thanks, Sam

Simple drill through action question


Im using the the below query as the condition for a Drillthrough Action

IIF([Load Date].[LoadDate].CURRENTMEMBER IS [Load Date].[LoadDate].LastChild, TRUE, FALSE)

I am attempting to confine this action to the last loaddate member. I'm thinking this is fairly easy to do, but I cannot seem to get it to work. I haven't been doing MDX for a couple years now so I'm probably missing something simple...? Thanks for any assistance.

End Using

Simple Question About Manipulating the ITextSelection of the IWpfTextView




I'm fiddling around with VS Extensibility and am trying to interact with the WpfTextView.


I'm struggling slightly getting to grips with the new model. Basically all I want to do is change the selected text (equivalent to TextSelection.CharLeft(true,1); using the older TextSelection object). This should be a case of interacting with some aspect of my IWpfTextView object's Selection property. But I can't work out which. 


How do I do this with the new model?



Simple JS question (dates)


I've 'inherited'  a website and although I'm happy with the .NET side of things I know very little about Javascript.  I've a simple validation function that isn't working.  I need to check that a date entered in a field is not after today.  The rest of the site is written in such away as to be culture aware and as such I don't have any hard coded date formats anywhere else.  Can I achieve this validation in JS without hard coding a date format?  Here's the code:

 function checkDate(src, args)
         var Received = document.getElementById('<%= txtTimeReceived.ClientID %>').value;
         var date_Received = new Date(Received);
         var currentTime = new Date();
       if (date_Received > currentTime )

Simple LINQ to SQL question


Someone help me with what I'm missing here...

I have a VERY simple file as you can see... just three tables.


The Problem is that if I do this somethign like this....

var patients = from x in db.CT_Patients
                     where x.CT_Visits...... (error here)


It doesn't display child properties for CT_Visits from CT_Patient like it should. I only get the standard LINQ queries like Select, Where, Orderby etc... What am I missing???
