This code raises an error ("An unknown error occurred while trying to navigate to event handler") in VS2010 when right-clicking on "DateTimeEditBox_ValueChanged" and choosing "navigate to event handler"

<ActiproEditors:DateTimeEditBox Grid.Row="1" Grid.Column="1"
CheckBoxVisibility="Collapsed"
SpinnerVisibility="Visible"
Margin="0,7,0,0"
HorizontalAlignment="Left"
EditableParts="Date"
Value ="{Binding ElementName=WhatsImportantForUser1, Path=StopDate}"
Format="D"
ValueChanged="DateTimeEditBox_ValueChanged"
/>

In addition, if I manually add the event handler in code (StopDateEditor.ValueChanged += new EventHandler<ActiproSoftware.Windows.PropertyChangedRoutedEventArgs<DateTime?>>(DateEditor_ValueChanged);), and then manually paste (ValueChanged="DateEditor_ValueChanged") into the XAML, it fails at run time with a binding error.

Something is wrong... we have a workaround by using code, but it is uglier than straight declarative XMAL.

Hi Crile,

This is a known issue with the Visual Studio designer, which has to do with the use of generic classes/event arguments. We reported this to Microsoft last year, but it appears to have fallen through the cracks. I've made an official connect report here: https://connect.microsoft.com/WPF/feedback/details/633757/xaml-designer-fails-to-add-handler-for-event-that-uses-generic-event-arguments
