Winforms data binding: Can a TypeConverter be used instead of the Format/Parse events?

Question

In a Winforms form, I want to provide visual cues to the user when an input field contains an invalid value. To that end, I want to bind the ForeColor property

c.DataBindings.Add("Checked", dataSource, dataMember, true, DataSourceUpdateMode.OnPropertyChanged );
