Passing Parameters (URI, MediaElement) To Button Triggers/StoryBoard

Hi.

I have XAML code in which a stack panel that contains a media-element and a button is defined. Whenever the button is clicked, some sound is made. Here's the relevant portion:

            <StackPanel Name="spPanel" Orientation="Horizontal">
                <MediaElement Name="mediaelementButtonInstructions" />
                <Button Name="buttonNew" Command="New" Width="Auto" Height="Auto" Content="_New">
                    <Button.Triggers>
                        <EventTrigger RoutedEvent="Button.IsPressed">
                            <EventTrigger.Actions>
                                <BeginStoryboard>
                                    <Storyboard>
                                        <MediaTimeline Source="Resources/Sound_ButtonNew.mp3" Storyboard.TargetName="mediaelementButtonInstructions" BeginTime="0:0:0" />
                                    </Storyboard>
                                </BeginStoryboard>
                            </EventTrigger.Actions>
                        </EventTrigger>
                    </Button.Triggers>
                </Button>
            </StackPanel>

That's working as expected.

Now I want do add more buttons, where each button uses a MP3 of its own. Besides, I want to avoid replicating the whole <Button>...</Button> section for each button. I tried to create a suitable resource (style, story-board, &c), but failed to find a way to specify for each button the name of its MP3 and the name of the media-element, and also failed to pass these to the that resource as parameters.

Does anybody know how may I achieve these goals?

Thanks,

Ofer
