c# 4.0 - WPF triggers VS Converter

Question

Which is better to use performance wise? Limitation of Converter compared to trigger and vice verse. Shall I limit use of converter because it can cause class explosion?

Answer 1

If you are into TDD development, it will be better choice to go with converters.

If there is no complex business logic or custom logic to be applied then go for Triggers. One more thing about the converters is that, there is a performance hit associated with using converters according to Laurent Bugnion (creator of MVVM Light).

You can see more insight on the performance hit from this post. DataTrigger vs databinding with converter performance wise

You can get more details on when to you use trigger and when to use converters from this post as well. Should I use WPF converter or trigger?

The decision can be taken based on the development approach you are following or going to follow. I prefer wrapping your view-model in a "WPF Viewmodel" concept most of the time.
