DataSource Controls :: Updating A Newly Inserted Row In A Tableadapter?
May 7, 2010
I need to insert two rows into a tableadapter - and then take the identity column from each row and update them into a column on each row.
My problem is that I cannot update a column on a newly inserted row. Stepping through the code seems to indicate that I have updated the column, but when I check the database - the column indicates null.
I have tried calling Update on the TableAdapter, then performing the update on the column, and then calling Update again, but the update still isn't taking.

I have a FileSystem based asp.net 2.0 app that uses Sql Server 2005 Express database.
I have only one dataset for this app with only 4 tables. After i have completed it to a part, a co-worker have added some Classes to it, which are not in same namespace of myBLL classes.
Then i tried added a new table to the dataset. It like all other tables in that dataset uses SQL Statements to access and manage data.
The problem started after i added that new table. I cannot access it from code. I can access all previous TableAdapters but not this new one.

I am using a FormView to populate data, then inserting it using a LinqDataSource. The primary key is an autoincrementing identity. I'd like to handle the ItemInserted event to update some other tables, but I cannot find how to get the primary key of the newly inserted record. The insert happens fine, but nothing for the PK.
I realize I can change to using a SPROC, or change to creating the new row and doing the insert myself, but I'd prefer to continue with the LinqDataSource's automatic insert.
How can I get the PK?

I have an SQL Server table named "Fields" with an autoincrement identity column "FieldID" as the primary key, an nchar column "Phrase" that textbox entries are to be stored in from a web page, and another column that is defaulted to null. The following is the recommended example on how to use Scope_Identity() to get a newly inserted table row identity value:
//C#
string query = "Insert Into Categories (CategoryName) Values (@CategoryName);" +
"Select Scope_Identity()";
int ID;
string connect = @"Server=.SQLExpress;AttachDbFilename=|DataDirectory|Northwind.mdf;" +
"Database=Northwind;Trusted_Connection=Yes;";
using (SqlConnection conn = new SqlConnection(connect))
{
using (SqlCommand cmd = new SqlCommand(query, conn))
{
cmd.Parameters.AddWithValue("@CategoryName", Category.Text);
conn.Open();
ID = (int)cmd.ExecuteScalar();
}
}
Obviously, this example uses a Categories Table in a Northwind database, which I do not have. So I am confused by how to adapt this example for my application. The following is my data context:
DataClassesDataContext db = new DataClassesDataContext();
Could you explain how I can adapt the example for my "Fields" table in my "EFMDB" database?

I am using an auto-numbering index column as the primary key for many of my tables. Is there any way for me to know what the new row count is for newly inserted rows?

after a DetailsView (DV) 'Insert' (triggered by a DropDownList (DDL)) the DV shows the first record (in the DDL)!Are there VS2008 means to keep / show the just entered data - again ready with the command row "Edit/Delete/New" enabling me to e.g. "Edit" the just entered data?This DDL/DV scenario works just fine but to show my just entered record I have to leave this page and start calling this .aspx page again in order to see the name in the DDL and, hence, in the DV.I.e. I'm looking for a kind of automatic 'postback' bringing my just entered data back

I setup my gridview to handle the edit,delete, and insert operations correctly. My grid also supports paging and sorting. My question is how to highlight and go to the newly inserted row in my grid?

I thought this would be easy before I started, but I should've known better.
I just need to get the value of primarykey from the newly inserted record so I can pass it in the query string to the next page the user will be directed to.
Here's my code:

I had found what looked like a good soultion yesterday by the moderator "ecbruck" at this post:
[URL], but after spending many hours trying to figure out why I couldn't get it translated and working in my own project, I found that MS Access does not allow use of an Output Paramter. And unfortunately I don't have time to teach myself a new database platfrom and am stuck with MS Access for the moment...teaching myself asp.net has my head spining enough as it is.

There are several articles and blogs that are sort of about this subject but I haven't found one on point. Wondering if anyone has done this? Using VS2008 creating an ASP.NET 3.5 app with a strongly-typed dataset connecting to an MS SQL backend. In one TableAdapter, I have a custom Insert statement that inserts the record into the primary table. There are two other tables the also need records inserted into them and those records contain the record ID from the primary table. Here's an example of what I'm trying to accomplish:

I have this Insert statement working fine: [Code]....
It inserts a new record into a single table. The PK is a field named QID.what the equivalent Update code would be? I'm not sure of the syntax for the Update values (old and new) and Where clause.I'm assuming something beginning with: existingQ.Update

I have a quite baffling problem. I've created a Table adapter with 3 queries. 1. GetMemberData() - Return ALL rows. 2. SearchMembersLastName(@q) - Return specified columns from rows that have a column starting with a specified letter. 3. GetMemberDataById(@id)
- Return all rows matching a specified ID.
The Problem is that SearchMembersLastName(@q) is returning ALL coloumns instead of just the ones I want. Here's the query that's in the Table Adapter:
[Code]....
The problem is that it is acting like:
[Code]....
Here's the code that's calling it:

I just can't figure out why this is happening, any help will be greatly appreciated.

I right click on a TableAdapter, select Add Query, select using QueryBuilder, then select a field to filter upon, and add Filter as =@BookStem. Automatically the QueryBuilder adds the WHERE clause to my new query:HERE (BookStem = '@BookStem')When I press OK, I get "BookStem in expression is not part of the query". And filtering doesn't work.

Here's a simple code snippet where I create a new Entity object and call SaveChanges() to create a new record in the mapped database table.
[Code]....
What I'm trying to figure out is whether there is a way to derive this new key for my entity, e, from the ObjectContext, m? The reason for this is that the way my actual code is structured, my entity object is already out of scope at the point where I call the SaveChanges() method.

I am creating a TableAdapter using corresponding wizard, with a GetDataByID() query. The select statement is like this:select * from books where ID = ?Thus books are filtered by ID. But in case a null is passed as a parameter, I want to select all records rather than none. Could you please tell me how I can do it?

I have created a function that is called when a user wishes to upload a file to the database. The problem I am having is that it won't write the files to the database anymore. This function used to work before I implemented a treeview (which connects to the database). I am struggling to see how the treeview could have cause the file upload to stop working (the error may not even be related to the implementation of the treeview).
The error message I am receiving is: 'Update' is not a member of 'CMS.SiteFilesDSTableAdapters.SiteFilesTableAdapter'.
The code for the upload function is:
<System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Insert, True)> _
Public Function AddSiteFile(ByVal FileData As Byte(), ByVal FileName As String, ByVal FileDescription As
[code]....
It is throwing the error at: Dim rowsAffected As Integer = Adapter.Update(SiteFiles)
' Return true if precisely one row was inserted, otherwise false
Return rowsAffected = 1
EDIT: I managed to solve this problem by following:
http://www.asp.net/%28S%28pdfrohu0ajmwt445fanvj2r3%29%29/learn/data-access/tutorial-69-cs.aspx
Basically, I had used an Inner Join to gather all the fields, and table adapters don't seem to like them.
INSERT INTO [SiteFiles] ([FileData], [FileName], [FileDescription], [FileType], [FileCreated], [FileCreatedBy]) VALUES (@FileData, @FileName, @FileDescription, @FileType, @FileCreated, @FileCreatedBy)

I'm lost as to where to look next. Here is a sample of what I'm doing:
[Code].... The related tableadapter insert statement was autogenerated by VS2008:
INSERT INTO [ProductCycleCountItem] ([ProductCycleCountLocationID], [ProductID], [CountOnly], [Status]) VALUES (@ProductCycleCountLocationID, @ProductID, @CountOnly, @Status);
SELECT id, ProductCycleCountLocationID, ProductID, CountOnly, Status FROM ProductCycleCountItem WHERE (id = SCOPE_IDENTITY())
With multiple users it's as if it was returning @@IDENTITY instead of SCOPE_IDENTITY(). The table will look like this:
id Location product
1 A 5321
2 A 8273
3 B 2827
4 A 1743
The returned dataset will look like this:
id Location Product
1 A 5321
2 A 8273
3 A 1743
Is it maybe a SQL Server (2005) setting that's incorrect?

Going to start this thread over so that it makes more sense.Anyways, my problem is that when trying to configure my ObjectDataSource in design mode, it only gives me 2 options and never gives me the option for the one I need. The other 2 work fine, but for some reason, this 3rd one will not show up in the list.I have a webpage with pics illustrating how I have it setup and the problem ----------> https://sites.google.com/site/configuringobjectdatasource/And I have another webpage with pics illustrating steps I have taken to fix this problem but still nothing -----> https://sites.google.com/site/configodspart2/what is going on and why it will not show up in my list when I try to configure?

I've got an odd problem and can't figure out what's causing it. We've got 2 different DataSets in the same project and I'm seeing different generated code from the MSDataSetGenerator. Both projects are .NET Framework 4.
In one DataSet, I can open the .Designer.cs file and there's a line like:
[Code]....
This essentially exposes a Transaction property to any partial class I create so I can do with it what I want (by setting it to something).
In the other DataSet no matter what I try to do, this Transaction property never gets generated. I've right-clicked on both DataSets and chose "Run Custom Tool" to get them to regenerate (I've even tried deleting the .Designer.cs file before doing this) and they both get generated the same.
I tried to make sure all the properties of the DataSets were the same. Both are using .NET Framework 4.0 and VS2010.
The file that does not generate the Transaction was from a .NET 1.0 asp.net web site that has continually been upgraded through different .NET versions. Right now it's at 4.0 but I don't know if that would have anything to do with it.

I spent about 60 minutes sifting through search engine listings trying to figure this out and couldn't find an answer, so I decided to make this post for others.
Situation: Using a Stored Procedure to insert a row and return the new row ID, explained here. In my case, I used the Idenity_Scope to return the new row, like so:
[Code]....
Next, following steps as described in link above, went into the dataset XSD page, configured the table adapter to use this stored procedure. By default, it wanted my return value to be set to some value, but I set to allow Null (makes sense, since I don't want to pass the value in, I want to get it out, so it should be null to begin with).
Problem: Where I ran into an issue was in the method to call this stored procedure. The intellisense displayed the prototype it was expecting, basicly like this:

I fill a GridView from a ObjectDataSource that points to a Typed DataSet.
I need to read a couple of row columns from the object data source that IS NOT part of the Gridview.
So far, I have found out that ObjectDataSource.ObjectDataSource_Selected is the right event to do this.
Examples on the internet refers to e.OutputParameters, but that appears to be empy even though rows are returned.
e.ReturnValue seem to contain a type related to the row type, but I cannot interpret this either.
