Following the MVC1 vers of Nerddinner, but using 2010 and MVC2. Never seen this error. Looked in controller, model, view. Where does MVC pass the identity value, and how to stop it? I have never had to set IDENTITY_INSERT in any app before.

I am working on a web app for an online photo album. It is the last project in Scott Mitchell's book: "ASP.Net 2.0 in 24 hours".
I am creating a page where users can enter new photo images. The functionality for uploading an image will come later. I am working on just inserting a new row into the Pictures table with an optional category, a required title and a required description.
I am getting an error when I try to insert a new row.
Here is a screenshot of the page with a shot of the dropdown list.
The Categories are user-specific. I am getting the correct values retrieved.
[URL]
There are two pretty simple database tables involved here.
NOTE: The CategoryID and PIctureID are both autoincrement integer columns.
[URL]
The page uses a DetailsView that uses a SqlDataSource that uses the Pictures table. (The DetailsView's Default Mode property is set to "Insert". The "Enable Inserting" checkbox is also checked.)
The dropdown list uses a dropdown control that uses a SqlDataSource that uses the Categories table.
When the "Insert" button is clicked the CategoryID value associated with selected (Category) Name on the dropdown list will be used along with the Title and Description values to insert a row in to the Pictures table. (If no Category value is selected, then a null value will be used for the CategoryID. This is OK because the CategoryID column in the Pictures table allows nulls.)
My problem is that I am getting this error:
Cannot insert explicit value for identity column in table 'Pictures' when IDENTITY_INSERT is set to OFF.
(FYI: I have the full version of both Visual Studio and SQL Server.)
Here is my source code for the page:

The field 'idUser' is autoincremented. When I use SqlDataSource with a DetailsView, add option it adds a record and autoincrements the 'isUser'.
I have an insert table with identity specification set. And I getthis error. I'm using a stored procedure to store it. How do I correct it. I'm also using a details view on my insert page.

The wierd thing is this was working fine and then it just started throwing this error,

i have created a web form, where i have 3 textboxes into a table and one submit button.
i would like to store values from the textboxes into my database (sql server) when i click the submit button.
but how to insert the value that is not in textbox into database which is primary key for table without identity column.
How to handle this error

I am inserting data into Employee table using stored procedure.In employee table EmpNo is identity column.Once i insert data into table stored procedure should EmpNo i.e identitycolumn value.
correct my stored procedure to returm EMpNo Identity column after inserting row.
alter procedure SAR_Sp_AddEmployee(@EmpName varchar(10),@CampaignID int,@startDate datetime) as insert into EmpMaster values(@EmpName,@CampaignID,@startDate)
I have a database table and the column that has identity specification set to true is not displaying in numerical order. Whether I use Server Explorer and use Show Table Data or I create an application to view the contents of the table using a DataGridView I see that column displayed with the numbers often though not always in a non-numerical order.
Does it perhaps have to do with the way the rows for that column were added or would it be something else. I was looking at the properties for that column but don't see what I would change to make the rows display in numeric order.
I am developing a asp.net application and i am using SQL Server 2008. I took a IDENTITY column as Record_ID for detail table where i will have trillions of records per year. So just want to ask whats the largest number record id (identity) column can hold and in ASP.NET which data type i should use to handle record id as i am using this id as a reference to update the table data. I don't want to end up being trapped some day.
View 1 RepliesI am in the process of creating my database and I have the pending question of whether I should add a UserID using INT to the membership table. I am not replacing the UserID that is a UniqueIdentifier I am just adding a UserID with INT.
The reason I want to do this is because I have about twelve other tables that uses the UserID column. It will be easy for users to insert data into the other tables and I foresee the tables getting to be millions of rows, by using an UserID INT it will avoid the mass amount of storage from the UniqueIdentifier column.
Now my question is what are my repurcussions of doing this? I've already found out one, and I believe it is my biggest question, if I were to create an insert command in .net how would I grab the UserID INT rather then the UserID UniqueIdentifier to insert it into my tables? For example, I can get the userid this way:
Membership.GetUser("username").ProviderUserKey.ToString();

I am doing a data warehouse project.I have two tables tblA (id, type) and tblB(city, no_crimes, type).I want to create (insert) a number of rows based on the value of no_crimes.For Example, in tblB(Leeds, 2000, murder). SO, I need to insert 2000 rows into tblA by a single INSERT statement (not 2000 statements).
View 3 RepliesI am facing a problem here. I have a column where the value is equivalent to my identity column's value. For an example, I have a column A store is "ABC0001" and the 0001 is came from a column called Column B which identity on. when a new record inserted and Column B is next identity number and Column A value is "ABC" and add number from Column B.
View 4 RepliesI've been working on this project which requires me to insert data into a database. Due to the complexities of the function that I am doing, it is more complex to use SqlDataSource and hence I've used the traditional method of inserting to the database. The codes are as follows:
[Code]....
I am not too sure why, but even though I've debugged numerous times and the data gets inserted into the database through the form view, I get this error on the page after everything is executed: Cannot insert the value NULL into column 'reviewDate', table 'ProrsumDB.dbo.Review'; column does not allow nulls. INSERT fails. The statement has been terminated. reviewDate wasn't null when I tried and there are no exception thrown.
I have a registration page that must contain a user id label. When a user tries to register, the label on the page should show the identity value for the registration before completion. How to do this?
View 1 RepliesI have a number of tables that together make up a "Test" that somebody can take. There are multiple types (scripts) of Test a person can take. I'm working on an Edit function that will allow somebody to edit the Test Questions. I want these edited questions to show up on all new Tests of that type, but still show the old questions when viewing past test scores.
To do this each "Test" has a TestId auto-increment identity (along with its name). When a test is edited I want to make a copy of the test with a new TestId and present the questions for editing.
So what is the best way to make the copy and insert it into my table using LINQ to SQL? This:
DataContext db = new DataContext(ConnectionString);
//Copy old test into identical new test but with a different script ID
var oldScript = db.TestScripts.Single(ds => ds.TestScriptId == oldScriptID);
var newScript = oldScript;
db.TestScripts.InsertOnSubmit(newScript);
db.SubmitChanges();
of course tells me that I Cannot add an entity that already exists.
Is the only way to do this to go through every column in the TestScript and copy it manually, then insert it, and the database will give it a new Id?
I have been searching on here for many hours and read many posts but for some reason I am being slow and cannot figure this out. I am writing a record and need to get the identity field back. I have tried many combinations based on what I have read but the below code is where I am sitting at now. it has appdatasource.ExecuteScalar() underlined and the error says 'ExecuteScalar' is not a member of 'System.Web.UI.WebControls.SQLDataSource'. I would be very grateful if someone could point out what I am missing to get this to work.
Protected Sub SubmitApp_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SubmitApp.Click
Dim appdatasource As New SqlDataSource
appdatasource.ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionString1").ToString

appdatasource.InsertCommand = "INSERT INTO APPLICATION (FirstName,MiddleName,LastName,AcceptTerms,IPv4Address,DateInserted) VALUES (@FirstName,@MiddleName,@LastName,@IPv4Address,@DateInserted);select @@SCOPE_IDENTITY"
appdatasource.InsertParameters.Add("FirstName", fname.Text)
appdatasource.InsertParameters.Add("MiddleName", minit.Text)
appdatasource.InsertParameters.Add("LastName", lname.Text)

View 3 RepliesI am quite new to LINQ, and I am stuck with this probably basic problem, but haven't been able to find a solution, so I thought I could ask here.
So, I have this repository where I put my functions for data accessing, and now I need to write a function to get all the applicants that have applied for this particular advertisement, and their values too. Now, the values are stored in a separate M:N table, where every row consists of the applicantID,advertisementID and value. I just wanna append the value to every applicant that I show, so that it would look like a Ranking List.
However, I do not seem to know how to select just the name column from the Applicant table, and just the Value column from the ApplicantValue table.
And there's this Iqueryable interface that further confuses me...
Here's my function to get the Applicants only:
[Code]....
Now, if I try to add to the definition of the type two columns, it says that it only messes with types, i.e. one type should be passed. So I figured I would do a ViewModel and then pass it, like this
[Code]....
and then in the function I have no idea how to pass the values:
