DataSource Controls :: The DELETE Statement Conflicted With The REFERENCE Constraint
May 12, 2010The DELETE statement conflicted with the REFERENCE constraint "FK_EquipmentStatus_MeetEquip". The conflict occurred in database "D:MEETINGROOMAPAPP_DATADATABASE.MDF", table "dbo.EquipmentStatus", column 'Fk_MeetEquip'.
I'm getting this error when i'm trying to delete a listboxitem. It's true that an other table (EquipmentStatus) is using the primary key attached to the listboxitem, but how can i delete all the rows that causes this problem? I've seen an example using stored procedure, but i dont understand it, since i haven't really worked with it before:
ALTER TABLE t2
DROP CONSTRAINT FK_t1id
ALTER TABLE t2
ADD CONSTRAINT FK_t1id FOREIGN KEY (t1id) REFERENCES t1 (t1id) ON DELETE
CASCADE
My listbox is using MeetEquip table which p-key is MeetEquip.ID, and the fk-key (which generates the problem) is fk_MeetEquip from EquipmentStatus table.
ADO.NET :: The DELETE Statement Conflicted With The REFERENCE Constraint = Occurred In Database
Oct 15, 2010I am getting the following error The DELETE statement conflicted with the REFERENCE constraint "FK_Person_Country_CountryID_CountryID". The statement has been terminated. I do not want the user to delete the country if there are any FK contrains. Or a better way will be to ask the user if they want to delete the records referencing this "Country".

DataSource Controls :: The DELETE Statement Conflicted With The REFERENCE Constraint "FK_tblAdvanceLink_tblLink"
Oct 3, 2010I"m using table adapters here. I tried to use the following in my table adapter:
ALTER TABLE tblAdvanceLInk
DROP FOREIGN KEY FK_tblAdvanceLink_tblLink
DELETE FROM [tblAdvanceLink] WHERE WebsiteID=@WebsiteID
The DELETE statement conflicted with the REFERENCE constraint "FK_tblAdvanceLink_tblLink". The conflict occurred in database "LinkExchanger", table "dbo.tblAdvanceLink", column 'LinkID'. The statement has been terminated
I get the same problem every time. So I read you could do this in a sql query. Why doesn't this work in my tableadapter? Do I have this in the right place? Do I also put this into the other table? (tblLInk) Isn't there a way to just relax ALL constraints so I can delete some rows? I'm deleting rows from both tables which have the corresponding websiteID

Way To Capture Unique Constraint Exception And Provide User-friendly Message
May 4, 2010Using vb.net/asp.net 2005 and SQL Server 2005:I have a unique constraint setup to prevent users from entering duplicate email addresses in my online system.When a user tries to edit an existing email to one that already exists (add a duplicate) it shows the following<ERROR>Cannot insert duplicate key row in ojbect "dbo.someTableName" with unique index.....The statement has been terminated This prevents the user from adding duplicates which is good but I would like to provide a more user friendly exception message and I do not want to show the table and field names to the user.

VS 2010 - Business Layer Constraint Error
Feb 22, 2012I'm working on an application using a 3 tier architecture and I'm having issues with a business layer select method. Basically, I have a gridview control that is populated by an objectDataSource. The ObjectDataSource calls a select method in the my business logic layer to retrieve data. When the business logic layer calls a table adapter method, I receive the following error message:
Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints
This is my first attempt at a 3 tier design and I'm not sure where to start with the debugging process.
Also, the stored procedure that is used by the table adapter select method, creates a new column inside of the query. This column is not included in the datasets datatable. I manually inserted a new column into the datatable from the dataset designer. The new column was created to store the values that are being returned from the new column in the stored procedure. I'm not sure if this is the correct way to do this or not but it allowed me to access the column in the business logic layer methods.

Forms Data Controls :: ListView Delete And Object Reference Not Set
Feb 18, 2011I keep getting Object Reference not set to an instance of an object errors when I try to use the ListView delete function. It is a fairly freshly created listview and is very close to the original template so not sure what is going wrong. Some possibly relevant code:
[Code]....
I also put in a breakpoint in the deleting event (only reason I added the deleting event) to look at the status of everything. When I do: Contact delContact = (Contact)e.Entity; and look at the values, the values for almost everything are set to null. It does have the correct value for the ID of the contact object that needs to be deleted. When I continue to step, it jumps to my designer.cs file and appears to break here:
[Code]....
likely because _Case_ID is null. The exact exception I'm encountering is: System.NullReferenceException: Object reference not set to an instance of an object. While I could probably re populate the object with correct values, that doesn't seem likely to address the real cause of the problem.
