DataSource Controls :: How To Insert SQL Record From C# Code Behind
May 31, 2010
I converted code from VB that works to c# to insert a record in an SQL daTA BASE.
The VB code is as follows:
Insert a new record into Contact
Dim connectionString As String = ConfigurationManager.ConnectionStrings("aspnetdbConnectionString").ConnectionString
Dim insertSql As String = "INSERT INTO Contact(UserId, Notes) VALUES(@UserId, @Notes)"
Using myConnection As New SqlConnection(connectionString)
[Code]....

Conseptually what I'm doing is simple, and technically it may even be simple, but I'm still rusty. Here's what I'm trying to do:
I have a webform that allows the user to enter a new record, and in there I have also included a couple FileUpload controls. Upon clicking the "Save" button, I'm saving the details entered into one table (ITEMS), and also inserting the FileUpload details (path, id, upload_user) into another table ATTACHMNTS). Because one ITEM can have many attachments, I needed to split the tables up. So on save, I need to save the ITEM, save the ATTACHMENT, and then also put the ITEM_ID in the ATTACHMENT table. I'm second guessing myself because I think all I'd have to do is after I do the ITEM insert, do a SELECT MAX on the ITEM table and hold the newest (MAX) id in a variable and then use it in the ATTACHMENTS update. I'm not 100% on this because there IS a chance that someone else could save a few milliseconds later and I'll link the wrong ITEM. See my delima?

I'm very new to this area and am using ASP.NET 3.5 with WMD 2008 Express Edition and VB code.
How do I write records to the SQL database using VB? I want to use the connection string, etc used in the ASP.NET controls if possible.
My website is a Rugby Club site and I've an SQL database of match fixtures which include TeamId(1XV, 2XV, etc.), Season(2008, 2009, etc) and match date.
I allow some users to update the fixture details but want to insert a series of new fixture records for the neext season which contain just TeamId Season and Match Dates. I therefore want to take the season and Team Id from label fields and then create match dates by adding seven days to a start date.

I use the following code to insert recode to a sql 2008 table, the field ID of DBProgram is IDENTITY, so SQL 2008 SERVER will pass a value to it automatically. How can I get the ID value of the record I just insert ?
DBProgram dbProgram = new DBProgram();
db.DBPrograms.InsertOnSubmit(dbProgram);
db.SubmitChanges();

I am going to insert Multiple record IN sql using storedProcedure from gridview...
for this purpose i am using cell concatinating method and send whole gridview cell data in string variable.
i have tried xml document method or sending data in table through looping as well but didn't satisfy from both of them... b/c concatinating method required a delimeter for seperation(for which i have restrict the user from that sepereator ) and xml method required an extra file which is not a efficient approach .

I have a page called Article.aspx that takes content from the database. I would like to use the title of the content as the title of the page for a little SEO I am doing. I setup a literal on the aspx page that must take the value of the content title from the code behind, what is the best way about doing this? I'm guessing I need to open a data base connection to read the record from the table but I am still learning asp.net and not sure how to write it

I have a scenario in which the user can add a new option to appear in the list of available choices in a DDL contained in a detailsview when they select an option <Add New>. This displays an AJAX model popup which then allows the user to enter the new option text. Then they hit an Insert button which inserts that new option into the DDL's datasource and I call ddl.DataBind. Subsequently I want to close the modal popup and then display the newly created DDL option as selected.
When I step through the code, everything appears to be working as expected...i.e. the DDL's datasource now has 1 more record than before and the ddl.SelectedValue is the newly created record for its datasource. I can also query ddl.items(99) and see the new option is part of the ddl's items collection and the new record is Selected.
HOWEVER, once the screen comes back from the debugger, the DDL is now showing the newly created option, but still the prior selected option of "<Add New>". And if you pull the DDL down the newly created option is not in the list?
I cannot figure out how that happens...though I suspect it has something to do with the AJAX/Update panel. Here's some code:

I am counting from a table for that i have written code as below
protected void get_Id_Afterpoint()
{
int counter = 0;
string strSql = "select count(*) as ID from tblEnergy where ID=?";
OdbcCommand com = new OdbcCommand(strSql, con);
com.Parameters.AddWithValue("ID", DropDownList1.SelectedValue);
OdbcDataAdapter oda = new OdbcDataAdapter(com);
DataTable dt = new DataTable();
oda.Fill(dt);
if (dt.Rows.Count == 0)
{
lblID2.Text = "1";
}
else
{
counter = dt.Rows.Count;
counter = counter + 1;
lblID2.Text = Convert.ToString(counter);
}
}
there is no record related to DropDownList1.SelectedValue. but as i am counting if(dt.rows.count) and i put break point on the bolded part it shows 1 record. how it can be possible?

@album_id int,
@album_name nvarchar (50),

SET
album_name=@album_name,
album_descr= @album_descr,
album_img_cover_id_FK = @album_img_cover_id_FK,
album_creation_date = @album_creation_date

I'm very new on VWD, but I got the hang of it for the past 2 weeks(thank you for all the videos posted here in ASP.NET),but I'm really weak on the coding part(vb & c#),except for all the sample shown on the tutorials. Anyways, I have a simple project that
does insert, update & delete to SQL express using the details view. But to complete my project, I need to add a button that will create an event to restore the very last record inserted in SQL and display it back into the details view for minor modification
and nserted again as the newest record with the mod. I'm doing this so user, doesn't need to re-key-in redundant information, like names, original date & time etc, and just make modification on the description of the last record.....
