I have a custom exception which gets thrown in my business layer. I catch it
in the item inserted event of my formview. How do I tell whether it is a
custom error or another type of error. Is there a way of saying is
"e.exception of type custom error". Regards, Chris.

Is it as simple as

If TypeOf obj Is TextBox Then...

I've logged off from my development machine and can't get access right now.

If you need to handle different exceptions in different ways, you should use
multiple catch blocks (sorry for the C#):

try
{
// ...
}
catch (MyException e)
{
// handle my exceptions
}
catch (Exception e)
{
// handle all other exceptions
}
