Hi,
I’m using VS2005 and the bindingnavigator control. Right now I’m using 2 bindingnavigator control (each for one table) in order to generate the new ID when I clicked the ‘add new” button. But I want to know what command and line of C# I must add to my program to generate the new ID when I clicked the “add new” button IF I want to have 1 bindingnavigator control for both of them.
Thank you
