Can not find DoubleClick in XAML

xaml double-click

I have a ListView control in XAML. The items are defined by a template control with a TextBlock inside a Grid. Now I want to trigger an action when I double click the TextBlock. To my surprise I find there is no DoubleClick event to hook up ... ! I thought it was just the TextBlock that din't have it, but actually no controls have it. I look for DoubleClick and MouseDoubleClick but they are definitely absent.

I have read suggestions where an EventTrigger is added to a control with Gesture="MouseDoubleClick". It looks promising but in my case the compiler complains and tells me there is no such gesture as a MouseDoubleClick. Same with DoubleClick.

Did the DoubleClick disappear in some version of .Net? I have .Net Framework 4.5 and the project is WPF Application.

Do I have to do stupid workarounds by detecting MouseDown and check the elapsed time since last MouseDown? Sounds like stoneage ...

It is always refreshing to formulate your problem! After thinking a while I thought maybe they added a counter to the mouse events instead of having separate events. That seems to be the case!!! The MouseButtonEventArgs has a ClickCount property. When checking for value 2 I detect my DoubleClick!

Still a bit odd though to just kick out the DoubleClick. Even after searching I find no reference as to when and why it disappeared.
