Cathcing exceptions from datasources

[fawkes]

I have a custom object and a collection that implements IBindingList and I use this collection as the datasource for a bindingsource used for a datagridview.

If the value for one property in my custom object isn't correct an exception is thrown but I can't catch it.

I've tried using BindingSourceComplete but if I put a break in the event handler for BindingSourceComplete the event isn't even raised.

I could with a pointer in the right direction here, I'm tempted to change from exceptions to raising events instead which can be handled.

What does the stack trace tell you?

Thanks for the interest, I discovered what I was doing wrong.

I've been able to access the object errors by handling the DataError event for the datagridview but for errors thrown by the collection I've changed these to events similar to the DataError event nad handle these seperately.
