How can I attach two attached behaviors to one XAML element?

Question

I\'ve implemented the attached command behavior pattern found here and it works well to allow e.g. a Border to have a left- or right-click event that fires

Answer 1

The link you sent contains that very answer. You can use the CommandBehaviorCollection.Behaviors capabilities in ACB v2.

   <Border Background="Yellow" Width="350" Margin="0,0,10,0" Height="35" CornerRadius="2" x:Name="test">
       <local:CommandBehaviorCollection.Behaviors>
               <local:BehaviorBinding Event="MouseLeftButtonDown" Action="{Binding DoSomething}" CommandParameter="An Action on MouseLeftButtonDown"/>
               <local:BehaviorBinding Event="MouseRightButtonDown" Command="{Binding SomeCommand}" CommandParameter="A Command on MouseRightButtonDown"/>
       </local:CommandBehaviorCollection.Behaviors>
       <TextBlock Text="MouseDown on this border to execute the command"/>
   </Border>

Answer 2

"that was it, thanks, funny though that my XAML editor gives me the error "The attachable property 'Behaviors' was not found in type 'CommandBehaviorCollection'." although I can run and compile it fine, why is that?"

The reason is that the code that allows the command behavior collection (which is an attached property collection) is actualy sort of a XAML loophole. You can read more about that here: http://wekempf.spaces.live.com/blog/cns!D18C3EC06EA971CF!468.entry?sa=276442122
