Hello!
I have problem! So, first of all I have page wich consist of 3 pages. In first page I press Button "Start" it will create empty record in my DB, in Page 2 is Form where I need to fill data and when I press Button "Next" it will update previos created record in DB, and in Page 3 it will update records created in DB.
Sorry for my language :)

For example Page 2 code

    }

okay...I dont understand the question first off. Secondly. Read about LINQ to SQL..its amazing, I used to do the same thing you are here...never again! Third. Insert does just that INSERTS a row of data (already populated). If you INSERT a blank row you will then need to UPDATE it to change the info in it...so blank row inserts are...no good.


Rephrase the question so we can answer it more directly.
