ADO.NET :: Adding Or Removing Result Columns From Edmx File?
Nov 29, 2010
I have a stroed procedure which is mapped in myEDMX file under EntityContainer >>Function Imports. When I add or remove a column from the stored procedure, I am not able to remove the old columns from the model. I right click on the stored procedure in Model browser and got to Edit Function Import. The return type is complex.
I select "get column information" and get the updated return fields but can not update the collection. It will work if I click on "Create New Complex Type" but it will generate a new name for the collection and the old collection is still in the mode. I even tried deleting and adding the stored procedures and can not get it to work. I can only edit the edmx.cs and the XML to remove it but there is got to be a better way.

I am building an application using Asp.Net 4.0 and Entity framework 4.
I have already created the model class (edmx) file using the Database-First method of the Entity framework.
Now I am almost nearning the end of the application. I have realised I need to add one more table to my database.
How do I add the newly created table to the model class (edmx) file.
If I again regenerate the model class, similar to what I did the first time i.e using the Database-First approach, will my current application be affected.
Will the already in use data like tables, relationships and views be affected in anyway.
Do I have to follow this approach everytime I need to add a new table to the entity model class.

I have an AJAX-heavy ASP.NET web application developed using .NET 4.0, using TFS as our source control. We recently upgraded our dev tools to use VS2010 and TFS 2010 exclusively, but now every time a file is checked out, we see visual studio reloading all the symbols, and all the sessions being dropped.
After putting some error logging code, we discovered the reason for the recycle is it reckons App_offline.htm is changing whenever we check out. This doesn't exist anywhere in the project, and my SO-fu has found some information about SQL Express making this file get created and deleted, so it's possible that's what's happening here.
It looks like I do have SQL-Express installed, but even disabling the services that are running, the problem persists.
Is there any way to stop a check out from adding/removing this file, if this is indeed what is happening? It's beyond frustrating to have the app recycle whenever I simply check out a file...

My Question is can we extend one context to another in Entity Framework 4. Following is the problem background.
I am using EF4 for developing a Web-Application. My Web Application has 3 projects.
One project is for storing candidate CV information.
Another project is for storing customer information.
Final project is called CORE. this CORE contains a edmx file that should be extended by CV and CRM.
As an example email address table can be shared by both customer (CRM) and CV. To share one table with another, we should be able to extend one context (CV context) with other context (customer context). Could some one having experience using Entity Framework share your experience with me to find whether this is possible.
We have 3 edmx files in three class libraries:
Person class library(Core) with core.edmx-Basic details related to a person(name, email) CV Class library with CV.edmx wich have CV related data(Experiance,skills) Customer Relationship management system(CRM) which have customer data(sales data...)
Then we want to use core class library edmx file(Core.edmx) with cv.edmx (basically cv tables should be able to use tables from core tables) . Same way we want to use the core.edmx with CRM.edmx for the 3 rd project

Till now I used to design RDLC file before and assigned typed dataset table columns.Report processing mode is local. But now my stored procedure returns different columns based on condition i.e columns are not fixed every time. Now I need to add that columns to typed dataset and dataset is assigned to RDLC file. So dataset and RDLC files are create dynamically based on stored procedure result set columns.

I recently started explore MVC and just tried some samples around, i.e. MvcMusicStore.
As the sample DB in MvcMusicStore is quite small, I am wondering how should I design the edmx/entity for a bigger database, let say for an enterprise application, which has more than 20 tables as in AdventureWorks?
Thus, the question is should I include all in one edmx/entity or I should include multiple edmx/entities when I designing the model?

I have looked at two of Microsoft's tutorials for MVC. In one tutorial they are creating a .edmx file to handle the Entity Framework in order to execute Linq queries. In another tutorial they made a class called "MusicStoreEntities.cs" here is the code:
using System.Data.Entity;
namespace MvcMusicStore.Models
{
public class MusicStoreEntities : DbContext
{
public DbSet<Album> Albums { get; set; }
public DbSet<Genre> Genres { get; set; }
public DbSet<Artist> Artists { get; set; }
public DbSet<Cart> Carts { get; set; }
public DbSet<Order> Orders { get; set; }
public DbSet<OrderDetail> OrderDetails { get; set; }
}
}
And the tutorial creates an instance of this class and starts doing Linq queries as well. What are the differences between these 2 methods? and how can I make DbSet objects in a .edmx file?

When I try to add a new stored procedure to an EDMX file, I try to get the column information for a complex type, I get the following error and can not register the stored procedure:
An exception of type Microsoft.SqlServer.Management.sdk.sfc.EnumeratorException occured while attempting to get column information. The Exception is:
ExecuteScalar requires an open and available connection. The connection's current state is closed. The inner exception caught was of type System.InvalidOperationException withthis message: Execute scalr required an open and ready connection.
I cann ot add the new stored procedure but everything compiles fine.

I am using vs2008 vb code behind. I am currently receiving an object through a web service that I serialize into xml. What I'd like to do after that is remove the namespaces, and add nodes to sort of customize my own xml doc. I am getting an error on this
Code:
Dim DOC1 As New XmlDocument
Dim STR As String
STR = ConvertObjectToXmlString(HODRes).ToString
DOC1.LoadXml(STR)

The error I get is:

I have a web project with a data model defined in an edmx file. The connection string starts like this:
metadata=res://*/;
This has worked fine for a while. But somebody else working on the project created a dll that also uses the entity framework and added it to the bin folder. Now when I try to create my connection there is an error loading the metadata.
Aside from totally changing the way one or both of us is doing things, I wonder if the problem can be fixed if my connection string can be changed to only look for the metadata defined in my edmx file. The problem is, for the life of me I can't find the right syntax to do this. The metadata is embedded in the output assembly, so there are no physical metadata files to point to. How exactly should I specify the metadata location in the connection string?

I would like to make some changes to my EF4 edmx file without modifying the file itself, mainly so I don't loose all my changes if I regenerate the model from the database. I'm familiar with XSL and have seen references made to using it in conjunction with the edmx file. This sounds like a great solution, however I can't seem to find any documentation on how to actually set this up. Do you reference the style sheet from the edmx file or do you configure it to look at the template and then load the edmx file in somehow?
Clarification:
Specifically what I'm trying to do is modify the model so that several of the views act as tables with relations within the model, see here: http://blogs.msdn.com/b/alexj/archive/2009/09/01/tip-34-how-to-work-with-updatable-views.aspx
The issue I'll have in using that method is if I need to update the database and regenerate the model I'll have to go back and make all of those changes again, I was hoping there was a way to use xslt to make those changes to the views so they would not be removed when the model is regenerated.

I need to add a table to a .edmx file. Earlier I had added that table, say, Table A to the edmx file. Since keys were not set, I had to delete it. Then in order to bring back the altered Table A to the file, I right clicked the file and clicked the option 'Update Model from Database'. But I couldn't find the table I deleted from the edmx file. It is there in the database. how can I bring the table back to the edmx file.

I am using C#.
I am having below code in C#:
protected override void OnInit(EventArgs e)
{
try
{
if (Session["boolSignOn"].ToString() == "true".ToString())
{
lblPanelOpen.Text = Session["panelOpen"].ToString();
}
else
{
lblPanelOpen.Text = Session["panelOpen"].ToString();
}
}
catch (Exception ex)
{
Logger.Error("Error processing request:" + ex.Message);
}
}
protected override void OnLoad(EventArgs e)
{
try
{
if (!string.IsNullOrEmpty(Session["panelOpen"].ToString()))
{
lblPanelOpen.Text = string.Empty;
Session.Remove("panelOpen");
}
}
catch (Exception ex)
{
Logger.Error("Unable to remove the session variable:" + ex.Message);
}
}
In above code I am having a Session["panelOpen"] variable which is created from another user control and once my page is trying to render, I am storing Session["panelOpen"] in my hidden lblPanelOpen.Text on page OnInit() method, however when page is loaded completely then I am trying to remove the session variable.

I can either put this node in my web.sitemap file and remove it in release builds.
Or Add the node in debug builds.

I've been at this same question in different forms now for a while (see e.g. Entity Framework and MVC 3: The relationship could not be changed because one or more of the foreign-key properties is non-nullable. ), and it's still bugging me, so I thought I'd put it a little more generically:
You have an entity object (using Entity Framework), say User. The User has some simple properties such as FirstName, LastName, etc. But it also has some object property lists, take the proverbial example Emails, to make this simple. Email is often designed as a list of objects so that you can add to that object properties like Address and Type (Home, Work, etc). I'm using this as an example to keep it generic, but it could be anything, the point is, you want the user to be able to add an arbitrary number of these items. You should also be able to delete items (old address, or whatever).
Now, in a normal web page you would expect to be able to add these items in the same View. But MVC as it seems designed only makes it easy to do this if you call up an entirely new View just to add the address. (In the template for an Index View you get the "Create New" link e.g.).
I've come across a couple of examples that do something close to what I mean here:
[URL]
and
[URL]
The problem is, although the sample projects on these sites work fine, with mock model objects, and simply lists (not an object with a child list), it's a different thing if you actually want to do something with the posted information - in my case save to database through the Entity Framework model. To adapt these cases to that, all of a sudden I'm in a maze of intricate and definitely not DRY code... Juggling objects with AutoMapper and whatnot, and the Entity Framework won't let you save and so on (see above link if you're interested in the details).
What I want to get at is, is it really possible that this is such an uncommon thing to want to do? Update a child collection in the same View as the parent object (such as the email addresses in this case)? It seems to me it can't be uncommon at all, and there must be a standard way of handling this sort of scenario, and I'm just missing it (and no one here so far has been able to point me to a straighforward solution, perhaps because I made it too abstract with my own application examples).
