Hi, I'm relatively new to XAML, so please bear with me if I'm what I'm planning to do is stupid. I'm not a big fan (yet) of the rather crazy syntax, especially when using {binding} and name:spaces. But I like the strict separation of logic and UI and would like to continue doing it that way. I'm firing a custom RoutedEvent from my Window class and use this as an event trigger in the XAML code. This works fine so far: <EventTrigger RoutedEvent="foo:Window3.BarEvent"> <EventTrigger.Actions> <BeginStoryboard> ... I'm doing this to display an error message under certain conditions (showing a big red and blinking panel to the user). What I've not found out is how one can use the event args of the RoutedEvent in the XAML code. I would like to pass the error message as a parameter to that event, so the trigger can assign it to the text property of a label control (probably by using an ObjectAnimationBase derived animation). What I'm having in mind is something like this: <EventTrigger RoutedEvent="foo:Window3.BarEvent"> <EventTrigger.Actions> <BeginStoryboard> <Storyboard Duration="00:00:10"> <ObjectAnimationUsingKeyFrames Storyboard.TargetName="SomeLabel" Storyboard.TargetProperty="Text"> <DiscreteObjectKeyFrame KeyTime="00:00:00" Value="{BarEventArgs:ErrorMessage}" /> However, I have not found a way to access the arguments passed to the RoutedEvent in XAML code. I'd appreciate any suggestions... Thanks! Jens |

As a follow up to my own post: is this the right group to ask such questions? I'm wondering because noone answered what I'd considered an easy question... Jens |
