routed-events

I'm showing a context menu for elements in a ListView . The context menu is attached to the TextBlock s of the ListView as follows. <ListView.Resources> <ContextMenu x:Key="ItemContextMenu"> <MenuItem Command="local:MyCommands.Test" /> </ContextMenu> <Style TargetType="{x:Type TextBlock}" > <Setter Property="ContextMenu" Value="{StaticResource ItemContextMenu}" /> </Style> </ListView.Resources> The context menu properly shows up and the RoutedUIEvent is fired as well. The issue is that in the Executed callback the ExecutedRoutedEventArgs.OriginalSource is a ListViewItem and not the TextBlock.

I read this good article about Routed Events, and I understood why we need sometimes bubble Events and sometime we need tunnel Events. What I didn't understand is, when we use the tunnel Event, why after it is handled or reached to the source element, still the bubble event is launched? Thanks in advance! The article says that if you put an image on a button, and that image is clicked, the tunnel event for that image will fire. But it is highly likely that you would also want to handle that click as if the button itself was clicked, so a bubble event is also fired which bubbles up to the click

I have following XAML <StackPanel MouseEnter="StackPanel_MouseEnter" Height="130" Background="Blue"> <Grid MouseEnter="Grid_MouseEnter" Height="60" Background="Red" > <Button MouseEnter="Button_MouseEnter" Height="20"/> </Grid> </StackPanel> In code behind I am doing this private void StackPanel_MouseEnter(object sender, MouseEventArgs e) { } private void Grid_MouseEnter(object sender, MouseEventArgs e) { e.Handled = true; } private void Button_MouseEnter(object sender, MouseEventArgs e) { e.Handled = true; } Now even if I move mouse over Button and set e.Handled = true , the events of Grid

I'm trying to use caliburn micro message to trigger an attached event that I created: public static class DataChanging { public delegate void DataChangingEventHandler(object sender, DataChangingEventArgs e); public static readonly RoutedEvent ChangingEvent = EventManager.RegisterRoutedEvent("Changing", RoutingStrategy.Bubble, typeof(DataChangingEventHandler), typeof(DataChanging)); public static void AddChangingHandler(DependencyObject o, DataChangingEventHandler handler) { ((UIElement)o).AddHandler(DataChanging.ChangingEvent, handler); } public static void RemoveChangingHandler
