Try...Catch block "pauses" while debugging

[axplains]

Pradeep, as Cicatrix says, the "OnValidate" event is a "default" one, i learned about it here:

http://weblogs.asp.net/scottgu/archi...-database.aspx
(See the "Custom Entity Object Validation Support" paragraph.
The examples are in C#, but not so difficult to translate).

I am using the same technique: the strange thing is that it does not break the program at runtime,
but only while debugging.
When it breaks, if I continue execution with F5, the program goes on without problems and executes
the "MessageBox.Show(ex.Message)" line correctly.
