You can use an output parameter of a stored procedure that performs the insert action, or you can use the Sql Data Adapter object's Row Updated method.
The simplest way to get the value of an IDENTITY column is to set up the identity value as an output parameter of a stored procedure and use the Sql Data Adapter to map that value back to the column in the Data Set.
When you add a row to a table, the application you're using doesn't need to know anything about the row's unique identity number; SQL Server just handles that part automatically.
However, in some cases, the application or the user needs to know the IDENTITY column's assigned value as soon as you add the row to the database.
event is raised when a row's Update button is clicked, but before the Grid View control updates the row.Free counters Added on January 19,2012 Follow Me @vmsdurano A bit About Me Disclaimer The opinions expressed herein are my own personal opinions and does not represent the opinions of my employers. Contol)Text; it werk just Fine any comment and thx for the code Instead of adding a Customer ID to your table and later pulling the text to get the ID number, a more reliable way to do it is to add a Data Key Names field to the grid example in the page: You can then access this information at any time with the following in code: Grid View1. Row Index]["id"]); You can do this with any field, but I've found customers get confused when they see the ID field and kept asking me why it was there, this also eliminates any issues if you change the display order of your table later (maybe add an edit/update/cancel control) Hey...great article ;)But I got a problem... So here I go with my example:protected void Grid View1_Row Updating(object sender, Grid View Update Event Args e) and the debugger says: Exception Details: System. Nor does it represent the opinion of my dog, because I don’t have one. I have a project that I coppied the above code into. Data Keys[Row Index]["Customer ID"]in the Update event it would be something like:int Customer ID = Convert. Format Exception: Input string was not in a correct format. For example, an order-entry application that uses an IDENTITY column for the order ID might need to provide an order-confirmation number to the customer immediately.In such a case, you need a way to retrieve the value of the IDENTITY column and display it in your application. NET lets you retrieve and display this value in a couple of ways.
