Question

Assume two controls:

<ParentControl ToolTip="{GIMME ChildControl.ToolTip}">
  <ChildControl ToolTip="Yay! Look at me! I'm bouncing off walls!!!"/>
</ParentControl> 

It’s the {GIMME ChildControl.ToolTip} I’m not sure about. I have an inkling it won’t work (what is a GIMME anyway), but I’m kind of failing here.

Things I have considered:

• {Binding RelativeSource=???} – but won’t that look in the bound data? I want to reference the child control, not something in the bound data
• {StaticRecourse useSameForChildControl} – except I’m setting the ToolTip property dynamically in the child control…

Answer 1

Ugly solution that will definitely work – give ChildControl a x:Name value, then bind {Binding ElementName=childElemName, Path=ToolTip}.

(Made into an answer as suggested ;))
