Going into Debug->Exceptions and simply clearing the clr check box is not the best work around for this problem.

You should add the exception:

System.ComponentModel.DataAnnotations.ValidationException

and clear the User-unhandled for only that particular one (since that's what's getting thrown).

Otherwise all user-unhandled clr exceptions will not cause a break in the debugger, and you won't know when your code is throwing an exception.

Yes, that is the right thing to do for now.

What is happening is that the Debugger is set by default to catch uncaught user exceptions, and if you run from the debugger when validation exceptions are thrown, you break to the debugger.

We're working with the validation and data-binding folks to work out a better story to avoid this exception being unhandled.

But your life will be simpler in the meantime if you use the Debug | Exceptions menu and uncheck "User-unhandled". This does not prevent the app from seeing these exceptions. It just stops the debugger from breaking when they occur.

In the debug menu in VS uncheck clr exceptions and run it

RIA CustomValidation(...) - [Required] [StringLength(3, MinimumLength=2)] -> ValidationException was unhandled by User Code

Hello,

i followed the RIA Overview PDF and added a shared.cs file to my Project in which i validate some other fields which works fine.
but if i add something like:

[Required]
[StringLength(3, MinimumLength=3)]
public string plz;

to the metadata i get the error: ValidationException was unhandled by User Code.
I thought it would just display the user that field plz hast to be at least 3 and at max 3 characters long.
How and where do i have to handle the Exception in my code?

thanks!
