Setting a value to a field in XPO

Question

If I want to assign a default value to a BO's field while saving it (in my Controller class), How can I achieve this using C# and xaf? Which events are relevant?

Answer 1

I solved the issue by adding this code to my overriden save methods:

    private void ProcessSelectedObject(System.Collections.IList list)
    {
        foreach (object obj in list)
        {
            if (obj is Contact)
            {
                if (((Contact)obj).Sector == null)
                {
                    ((Contact)(obj)).Sector = "Default";
                }
            }
        }
     }
