I am having trouble with foreign keys Dynamic Data and entity framework 4.0. It feels like there is a problem with the entity association but I am not sure. I have multiple fields representing the foreign key on the insert page.
When I try and insert data I get an error A dependent property in a ReferentialConstraint is mapped to a store-generated column.
Column: 'CommentId'
My data is a very basic one to many relationship, the foreign key in question is BookId in the Comment Table.
[code]...
When I let the scaffolding do its thing, I get multiple fields representing the foreign key.

I have a database with a 1 to many relationship in SQL Server 2008. I have created a formview in VS2008 to insert records into the child table. However I can't set the foreign key to automatically insert this value. If I manually type in a value the insert works but I need it to pick up the fk ID automatically from the master table. How can I do this?
The master table: tblTopic has ID int auto increment primary key and the child table has ID int auto increment primary key and TopicID int allow duplicates no nulls, foreign key. I have set updates to cascade in the relationship.
My insert statement is INSERT INTO tblTopic (TopicID, Comment, SubmittedBy) VALUES (@TopicID, @Comment,@SubmittedBy). The TopicID keeps throwing the error, this is the foreign key.
This is the first time I have tried to do this, so apologies if it's really obvious but I'm on a bit of learning curve.

I cannot get the value from the drop down list and I not sure what's wrong with the declaration and the code.
Dim selectedIntake As String = intakeDropDownList.SelectedItem.Text()
Dim selectedSupervisor As String = supervisorDropDownList.SelectedItem.Text()
.supervisor_ID = selectedSupervisor(0), _
.semester_No = selectedIntake(0) _
[Code]....
This is the error message I get :
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_student_Details_lecturer_Details". The conflict occurred in database "SKTM-AAS", table "dbo.lecturer_Details", column 'supervisor_ID'. The statement has been terminated.

I am trying to insert a foreign key into detailsview so that user didn't have to enter value every time. I am using the following code to do this but it is failing. I am not sure what needs to be done now.
Protected Sub LinqDataSource1_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.LinqDataSourceInsertEventArgs) Handles LinqDataSource1.Inserting
LinqDataSource1.InsertParameters("Company").DefaultValue = Session("Company_new").ToString()
End Sub
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim company As String = Request.QueryString("Company")
Session("Company_new") = company
End Sub
End Class

There is this error troubling me whenever i tried to do something to the ShopCart such as add to cart.
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_ShopCart_Shopper". The conflict occurred in database "DIYERA", table "dbo.Shopper", column 'ShopperID'. The statement has been terminated.
I checked the database and the foreign key, ShopperID, was set correctly.

I am trying to create a stored procedure where I can insert null values in columns that have a foreign key constraint and allow nulls. The columns I am trying to insert nulls into are commentid and imageid. I have created an Insert statement in a stored procedure and I get the foreign key constraint error. Can you tell me how to allow inserting data in the other columns without having to insert anything in the commendid and the imageid?
Here is my exec of the stored procedure that is not working:

I have two tables
Employee Table : ( EmployeeID,EmployeeName,... Etc )
Bonus Table : ( BonusID,EmployeeID,BonusDate,Bonus Reason,... Etc )
I wanted to list the bonuses in a gridview, so i made a query to return list of bonus records and my data access object returns the result set as Bonus business object ( generic collections of bonus BO ). i have bind my gridview with the bonus collection.

I have these two tables in my diagram:
the 1st:
PAR_TipiDocumento with
idTipoDocumento PK
idClasseDocumento
[...]
the 2nd:
PAR_ClassiDocumento with
idClasseDocumento PK
[...]
and a foreing key FK_PAR_TipiDocumento_PAR_ClassiDocumento from PAR_TipiDocumento.idClasseDocumentoto PAR_ClassiDocumento.idClasseDocumento.
This is my .cs code for the metadata:
[MetadataType(typeof(PAR_TipiDocumento_Metadata))]
[DisplayName("Tipi Documento")]
public partial class PAR_TipiDocumento[code]....
The problem is that in the Dynamic Data generated pages I correctly see all the display names "Tipi Documento" except for the header row of the PAR_ClassiDocumento table where I have "PAR_TipiDocumentos" (the plural generated by LINQ to SQL). The values under this column are correctly rendered as links to the PAR_TipiDocumento table with the right display name ("View Tipi Documento").
How can I change the Display Name of that "PAR_TipiDocumentos"?

Has anyone used a control that would allow them to select and bind to another data control with a foreign key? I have a grid that I can filter with a datalist and listview, but, I have a many to many relationship in the table I want to use in a control to further filter the grid that only has a foreign key to the table data in the filtered grid.

I have the following tables in my database which are as given under:
[code]...
My requirement is instead of getting the PromotionID values displayed for columns CustomerPromotionDiscountID & EmployeePromotionDiscountID, it should display the respective DiscountAmount. Which is not happenning for some reason.
I somehow found a workaround where if i define the datatype for columns CustomerPromotionDiscountID and EmployeePromotionDiscountID as nchar or nvarchar, it displays the DiscountAmount.
Wanted to know if there is any better way of doing this without changing the datatype for my columns?

I'm using Asp.Net's Dynamic Data Website project type.I've created a db that has one to onerelationship between two tables specified using a foreign key, (this could be one to many but I've used the linq designer to change it to a one to one relationship).i.e. I have a table Invoice and table CreditNote that takes an Invoice_Id as a foreign keyI was hoping that when I navigated to CreditNotes/Insert.aspx that it would display the a list of InvoiceIds in a dropdown list. It almost does this - it creates dropdownlist but only populates option value and not the text so I get something like this in the html source (notice only the value is populated - which looks empty to the user):
<select>
<option value="someInvoiceId"></option>
<option value="someInvoiceId"></option>
</select>
