Noobie question

I fully admit to being a novice, and I know a lot of what I am asking is basic, but I am under a time crunch and could use some guidance. I have a web application that I am writing that collects information for insertion into a database table. A part of this is having the user fill out some information that is placed into a gridview control, and could be multiple rows in that gridview. I have no problem saving the data IF there is only one row in the gridview, but when I loop through the rows to save multiple row values, the SQL stored proc seems not to handle the rows beyond row 1. It returns the stored proc error of too many arguments. I feel certain this is due to one of 2 things: (1) the stored proc is looking for various values, and from the gridview it is collecting the row values, then executing the stored proc, and when multiple rows are populated, there are more values than the stored proc has or (2) being a novice, I am approaching this wrong from the get-go.
My question is how to save these multiple row values to the database. The code to save follows:

Code:

The stored proc is a simple insert statement using the variables indicated in the code above.

Any help available?

Ok... you're using Parameters which is EXCELLENT (you don't know how many people I have to tutor on SQL injection hacks).

I think the problem is you're using them with "AddWithValue" which is great if you got one command you're firing off to a database, but not great if you want to send a whole bunch with different values.

Here's a quick example of a loop that sends 10 INSERT statements to a database:

Code:

---

        Using conn As New SqlConnection("Data Source=server;Initial Catalog=database;User ID=user;Password=password")
            'Insert 10 items into a database using a single SQL command and parameters
            conn.Open()
            Dim strSQL As String = "INSERT INTO table (name, number) VALUES(@name, @number);"

            Dim cmd As New SqlCommand(strSQL, conn)
            cmd.Parameters.Add("@name", SqlDbType.VarChar, 30)
            cmd.Parameters.Add("@number", SqlDbType.Int)

            Dim names() As String = {"Amber", "Bob", "Charles", "Danielle", "Edward", "Fiona", "Gary", "Helen", "Ivan", "Julie"}
            Dim numbers() As Integer = {10, 9, 8, 7, 6, 5, 4, 3, 2, 1}

            For i As Integer = 0 To 9
                cmd.Parameters("@name").Value = names(i)
                cmd.Parameters("@number").Value = numbers(i)
                cmd.ExecuteNonQuery()
            Next
            conn.Close()
        End Using

Jennifer - Thanks for the pointers. I have made some adjustments, and perhaps I am not understanding, but I am now getting errors that @intcounty variable has already been declared and must declare scalar variable @toco. Also, in the original code, I am doing some math calculations. Now sure how these will be done under the current scenario.
Current code:

Yea, @intcounty variable has already been declared and your problems are because you got them INSIDE your loop, and you're not setting the VALUES anywhere.

Honestly, your code makes absolutely no sense to me. I copied it into an editor and I tried to follow it... you're looping through GridView2m then for every row you hit, you loop through GridView2 completely again... so if you got 10 things in GridView2, you'll have 100 things in your database... and then you got GridView1 that you're looping through, and I don't know why, because only the last value is going to be recorded in the database... and you got that looping twice, and as many times as GridView2 so once again, with 10 things in GridView 1 and 10 things in GridView2, 1000 times there.

What EXACTLY are you trying to do? Post up a screenshot of your Form with some data in it so I can make sense of your intent so I can figure this out.

Thanks again, and I understand your confusion. The web form follows. Basically there are 2 gridviews, that could contain multiple rows of data.

Ok, and will these gridviews have the same number of rows each? If GridView1 has 10 rows, will GridView2 always have 10 rows?

If they do, does the data in Gridview1.Row1 correspond to the data in Gridview2.Row1?

If not, how is the data in Gridview2 related to the data in Gridview1?

Are they related at all? Should this be something you should be using 2 tables for because you have 2 lists of data, rather than trying to combine them into 1 table?

The gridviews contain different information, and not the same data in the gridviews. The number of rows can be different in each gridview. Like I said, I may be approaching the wrong from the get-go..
