It seems that NoesisGUI doesn't currently provide a standard way to validate input data. Is there any plan to support it in the future ?

# In WPF, the standard methods include the use of INotifyDataErrorInfo and IDataErrorInfo (ref: https://stackoverflow.com/questions/195 ... on-c-sharp).

Do you have any sample to achieve similar behavior with the current NoesisGUI ?

Yes, we have plans to incorporate data validation to bindings.

We don't have an example showing this kind of error validation. Right now it can only be achieved by exposing new properties in the ViewModel that can be used in the TextBox template to show the errors.

Any news on this?
Is any of the WPF mechanisms implemented in the meanwhile?
ValidateOnExceptions for example is not working...

EDIT: To extend the question a bit: is there a way to react on an exception thrown in a binding? That's one of the ways WPF handles validations via ValidatesOnExceptions.

Unfortunately there is no data validation implemented yet. Could you please create a ticket in our bugtracker asking for this feature?

As I said before the only alternative is extending viewmodel with properties that can be used in the data templates to show validation states.

Thanks for your response!
Since we have panels with 30-40 text boxes that would clutter our view models just because of validation properties. Not sure yet how to work around this...
I'd still prefer to simply throw exceptions in the VM properties and handle them in the UI but since the exceptions are silently swallowed by Noesis, I can't find a way to react to them.
But I'll find a way and I'll probably post our approach here. ;-)
