Hi In my database, I have a composite unique key constraint (CustomerId, Name) on a entity. I want to test if the unique constraint is upheld before submitting changes to the database. The user can customize the Name attribute on the entity, so I would like to make a custom validator that validates the name property, but while doing it,...
I have a TextBox whose value is passed to an int property in an object after being parsed to an int. When I use a ValidationProvider this conversion step is ignored when validating and I get an error telling me that I cannot save the string to an int32.

I want to add validator attributes to my domain models (in an ASP.NET MVC app), and I'm trying to decide between 2 frameworks, the Validation Application Block and DataAnnotations. They appears to do similar tasks, so I want to pick the one which will be the most supported/used in the future. It seems DataAnnotations are newer (and built...
I have set up a ruleset in my configuration file which has two validators, one of which is a built-in NotNullValidator, the other of which is a custom validator.

Scenario A .NET/WPF desktop application should be localized (or in MS terms globalized) to a different language than English. That is, the UI needs to be adopted completely (labels, icons, ...).
