It might sound like a silly question, but since I’d like to use your NegateConverter source code as-is in my (commercial) application, is there any license agreement I must follow to do so?

If there is, can you point there so that I can copy-paste it to my documentation? If not, please confirm so…

Thanks a lot for your helpful contributions to all of us, Ziev

Update: Nice! I just realized that if just pass the strings back from the converter, the binding system will take care of converting them to the target type. In other words <BoolConverter True=”Green” False=”Red” /> will get converted to SolidColorBrush automatically.

@mpg: it’s not that hard: just write one, give it 2 properties: OnTrue and OnFalse (which can be of a specific type, for instance Visibility, but also just a generic Object so that you can have a bool2something converter).

When you convert, you just do: (bool)value ? OnTrue : OnFalse

In XAML, that becomes:

or

Don’t forget to give them meaningful defaults, so that you can omit them for common scenarios.

I find myself sometimes having to do things like “set Visibility to Visible on Control A if P”, which entails often making a “BoolToVisible” converter. But then somewhere else I have to do “set Visibility to Visible on Control B if not P” — for which I wind up writing another, almost but not quite identical, “inverseBoolToVisible” converter.

Is there a way to avoid writing the extra converter?
