WinForms has great databinding support, and the ErrorProvider makes it quiet easy to display business object errors.
However, the conversion errors seems to be swallowed. If I type 'aaa' into a TextBox databound to an integer property, I get nothing from the ErrorProvider. So in this case my UI tells me everything is fine, when 'aaa' is clearly an invalid value for an integer.
I must be missing something!?
