SCOPE IDENTITY Using SqlDataSource WITHOUT Stored Proc

Ok, So I am trying to do 1 insert into a table and then insert more information into another table but I need to get the [TKTNUM] (the column with the idenity increment on it) value that was auto-generated when the insert was done. I have done a search and I am well aware that this are tons of posts on this subject already that is how I found out to use the SCOPE IDENTITY(). But nobody is using the insert syntax that I am using and since I am new, I don't understand any of it. I think they are using ADO.NET. I am extremely new to ASP.NET so take it easy on me ok guys... But can someone take a look at my code and tell me what the problem is. Again, I'm new so I am learning as I go so I might be missing something really stupid. Any help would be greatly appreciated. O yeah, I am running this code in a button click event NOT in a stored procedure (dont really know now to use those anyway).
Here is my code:
Protected Sub submitBtn_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim newTktNum
If Page.IsValid Then
Dim it3Conn As SqlDataSource = New SqlDataSource()
it3Conn.ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionString1").ToString
it3Conn.InsertCommand = "INSERT INTO [IT_TICKET] ([REQUEST_DATE], [LOGGED_BY], [REQUESTED_BY], [TKTSTATUS],[NEEDED_DATE]) VALUES (@REQUEST_DATE, @LOGGED_BY, @REQUESTED_BY, @TKTSTATUS,@NEEDED_DATE); SELECT @newTktNum = SCOPE_IDENTITY()"
it3Conn.InsertParameters.Add("REQUEST_DATE", DateTime.Now.ToString)
it3Conn.InsertParameters.Add("LOGGED_BY", User.Identity.Name)
it3Conn.InsertParameters.Add("REQUESTED_BY", User.Identity.Name)
it3Conn.InsertParameters.Add("TKTSTATUS", "NEW")
it3Conn.InsertParameters.Add("NEEDED_DATE", needByTB.Text.ToString)
it3Conn.Insert()
End If
MsgBox("Ticket Number: " & newTktNum & " has been created", MsgBoxStyle.OkOnly, "Ticket Created")
End Sub
