I a have a Checkbox on my form witch checked property is bound to a single object's boolean property. The update mode is set to OnPropertychanged cause there's no need for validation and i don't want the user having to click else where or press tab to commit that kind of change.
The problem is that the BindingSource calls the object's property setter a second time right after the checkbox looses focus just as if the update mode was OnValidation! That cause a terrible mess in my application...
The object implements the INotifyPropertyChanged but i removed the call to my helper method that raise the PropertyChanged event to see if that was the cause of that double call and it's not.
I just don't get it! why that behavior?
