c#

Hello, I have a system with 3 layers and I am using LINQ-to-SQL to persist.

I want to validate if the description field of my object is empty. I am using partial classes and the method OnValidate(). If the field is empty, it throws an exception.

Is this correct?

What do I do after the exception to not close the form, letting the user continue working?

Thank you very much

Sorry for my poor english

Ran into an odd behavior today with a many to many mapping of one of my tables in LINQ to SQL. Many to many mappings aren’t transparent in LINQ to SQL and it maps the link table the same way the SQL schema has it when creating one. In other words LINQ to SQL isn’t smart about many to many mappings… >>> More

Dynamic Type to do away with Reflection

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
