RoutedEventArgs vs EventArgs

Question

I am learning WPF / Silverlight and saw in an MS vidcast that it is now recommended to use RoutedEventArgs over EventArgs; although it didn\'t say

Answer 1

Say we have a Button element containing other elements, a StackPanel, itself containing a TextBox and an Image element.

The Button element should be able to handle a click event no matter if the Image that got clicked or if the TextBox was.

Hence WPF provides a way to :

• Propagate an event through element tree most of the time bubbling from the source element (here say the Image), to a higher level toward root element (for instance the button here).
• Handle such a propagated event.
