Hi Rob Ainscough,
During the Q1 2011 release we changed the implementation of the RadTabControl
in order to fix many bugs and improve its design. One of the changes is that it now inherits from Selector.
However, due to backward compatibility issues we couldn't change the old RadTabControl Selection Events
arguments type and therefore we had to define a new SelectionChanged
event with the same name but different arguments type.
However the VS feature for attaching events with Handled
keyword in VisualBasic
finds both events. The only difference between these two events is the type of the event arguments. However, RadSelectionChangedEventArgs
derives from SelectionChangedEventArgs
and those two classes are almost identical. And you can use either one of the two events.
We are researching the topic in order to make the VisualStudio display only the first event.
