Prevent hyperlink Click event from bubbling up - silverlight

Question

I'm designing a windows Phone app. I have a Hyperlink object in a RichTextBox, in a Grid. The Grid had a Tap event, and the Hyperlink has a Click event.
Clicking the Hyperlink also raises the parent Grid's Tap event. How can I prevent this?
I would use e.Handled in the Click handler, but RoutedEventArgs do not have a Handled property in Silverlight for Windows Phone... I also tried walking the logical tree to look for the original source, but the click appears to originate from a MS.Internal.RichTextBoxView control (e.OriginalSource)...

I don't think there is any good way from within the Click handler itself. The following state management can work though:
XAML:
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0" Tap="ContentPanel_Tap_1">
<RichTextBox Tap="RichTextBox_Tap_1">
<Paragraph>
fdsfdfdf
<Hyperlink Click="Hyperlink_Click_1">fdsfdsfsaf</Hyperlink>
fsdfsdfa
</Paragraph>
</RichTextBox>
</Grid>
and the code:
bool RtbTapHandled = false;
private void Hyperlink_Click_1(object sender, RoutedEventArgs e)
{
System.Diagnostics.Debug.WriteLine("Hyperlink");
RtbTapHandled = true;
}
private void RichTextBox_Tap_1(object sender, System.Windows.Input.GestureEventArgs e)
{
if (RtbTapHandled)
{
e.Handled = true;
}
RtbTapHandled = false;
System.Diagnostics.Debug.WriteLine("RTB_Tap");
}
private void ContentPanel_Tap_1(object sender, System.Windows.Input.GestureEventArgs e)
{
System.Diagnostics.Debug.WriteLine("Content_Tap");
}
In this case if you click on the RichTextBox you'll get callbacks from both RichTextBox_Tap_1 and ContentPanel_Tap_1, but if you click on the Hyperlink you'll get Hyperlink_Click_1 and RichTextBox_Tap_1 though it'll be handled at that level and stopped.
