ASP.NET: Retreive ID of inserted record

I needed to be able to access the returned identifier value from an Insert operation on my ASP page, so that I could use the value in other controls. You can do this by adding an event handler to your ObjectDataSource:

Protected Sub ObjectDataSource1_Inserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceStatusEventArgs) Handles ObjectDataSource1.Inserted
Dim returnvalue As Int32
returnvalue = Convert.ToInt32(e.ReturnValue)
' Do what you need to do with the ID here
Session.Add("CustomerID", returnvalue)

When your ObjectDataSource fires its Insert method, the value that the underlying BLL method returns is available for you to use in the above method. You can then set a session variable with this ID or do something else with it.

Just make sure that your BLL is returning the ID properly, or this won't work.

Job done!
