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?
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.
View 2 RepliesI 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.InsertCommandType = SqlDataSourceCommandType.Text
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)
appdatasource.InsertParameters.Add("DateInserted", DateTime.Now())
appdatasource.InsertParameters.Add("IPv4Address", Request.UserHostAddress.ToString)
Dim appid As Integer = appdatasource.ExecuteScalar()
End Sub
The scenario is that I wanna insert a record to the database via INSERT query and I need to user the identity number of this record in the INSERT query.
But I don't know how to achieve this.
Here is my table structure and code for your better understanding.
There are three columns in the Table: categoryID, categoryName, categoryPath. I need the path based on the categoryID which is an identity int column.
Now I used this code to do INSERT:
[Code]....
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.
Exception Details: System.Data.SqlClient.SqlException: Cannot insert explicit value for identity column in table 'Insert' when IDENTITY_INSERT is set to OFF.
I want to know if it's possible to return the identity value after an insert working with just the insertCommand and the insert parameters - something like this (but this isn't working):
Code:
<asp:SqlDataSource ID="sqlCustomerInformation" runat="server" ConnectionString="<%$ ConnectionStrings:SloanLEDLightingSystemsQuoteToolConnectionString %>"
SelectCommand="SELECT quoteCustomerInformationId,contactname FROM QuoteCustomerInformation order by quoteCustomerInformationId"
[Code] ....
Not sure what's wrong with my code. Should I be doing this in the code behind? I'm also confused as to how I would then retrieve the identity value in the code behind - on iteminserted.
The wierd thing is this was working fine and then it just started throwing this error,
"Cannot insert explicit value for identity column in table 'Reports' when IDENTITY_INSERT is set to OFF."
Here is the code:

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.
This would seem to be quite a trivial task, however I am having trouble retrieving the identity of the record inserted using the detailsview.insert() in the code behind. It would seem that detailsview.DataKey.Value would contain this value, but it is null after the insert is performed.

The field 'idUser' is autoincremented. When I use SqlDataSource with a DetailsView, add option it adds a record and autoincrements the 'isUser'.
I have made a AutoNumber Identity Column and iset Identity Specification property to "Yes" to keep the Identity Increment and Identity Seed values as default ones.
But when i use a datagriview and use a table adapter the column don´t appear on the datagridview.
Me.AUTONUMER2TableAdapter1.Fill(Me.Teste1DataSet3.AUTONUMER2)
So how to show to a AutoNumber Identity Column on a datagriview ?
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 trying to use a DetailsView to enter a new row into my database, but need to enter a further row in a linked table at the same time.
I am able to use the "iteminserted" event to gain control after the event has completed, but I need the key to the row i just inserted into the main table.
I am using a dataset, so the insert is managed by a tableadapter which has been configured to return an integer with the newly created identity of the row i just inserted.
Does anyone know how I can get access to that identity? is it in the "e" object of iteminserted? how do i find that if it is?
Here is the VB CodeBehind I am using to insert the row in the linked table (the DetailsView has just inserted a row into the "Books" table and the database has just assigned it an identity which should have been returned to somewhere by the tableadapter. I need that identity as a key to the "BookAuthors" table):

This is the ASP code for the DetailsView and the DataSource:

I have a problem with DetailsView linked with Database, DetailsView is Insert/Edit enabled, and adding/ediditng data works, however........ when I add a new record (DetailsView in Insert mode) and press INSET instead going to record I have just created in Read-Only Mode it shows me blank form, it looks that the "linking" field is null.
View 3 RepliesI 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.)

View 1 RepliesHow would I go about showing the insert row in a ListView? Intially, when I went to configure the ListView, the Enable Update, Delete and Insert checkboxes were all greyed out. I changed a bit of the template code and couldn't access this screen anymore but that's not really a big issue.The Edit and Insert templates are present in my source. To get editing working, I simply adding an asp:Button to each row with the CommandName 'Edit'. However I'm a bit confused as to how I can get the insert row to show. Do I have to create a new button there with the 'Insert' CommandName? If so, where should I put it? Is there another way of doing this?

I have a gridview and detailsview that are connected. When I delete records everything works fine except when I delete the last record in the gridview. I want the detailsview to revert to insert mode when I delete the last row in the gridview. Instead the detailsview shows up blank. I want to show the detailsview in insert mode after last row in grid has been deleted? How can do I this?

It should be simple, but I didn't found yet how to do it. There is only one user (Admin with user name and passowrd, he has a cookie so I know when he is watching the page) I would like to show him the Update/Delete/Insert button options in my ListView, but to the other users I don't want them to be able doing this kind of things, So it should be hidden from them. How I am doing it in C# code? Showing/Hiding these buttons?
