TemplatedParent - A clarification

Question

Here's the Tree:

• MyControl : BOUND(IContentMenuItem)
  • ControlTemplate
    • ContentPresenter : BOUND(Header, HeaderTemplate, HeaderTemplateSelector)
      • DataTemplate (For Header)
        • Label

I Want to bind The Label @ the end of that tree to a property on the DataContext of MyControl

I can use FindAncestor to get the MyControl (Obviously) but how do I bind to it's DataContext (of type IContentMenuItem)

---

Now for the Templated Parent Question

Will Binding to the TemplatedParent inside the DataTemplate in effect bind to The ContentPresenter, The ControlTemplate, or The MyControl ?

Answer 1

I think the answer to the TemplatedParent question is the ContentPresenter -- it is whatever the template is being applied to.

If you can get MyControl using FindAncestor, then you can bind to properties of the DataContext like this:

<Label Content="{Binding DataContext.MyProperty, RelativeSource=…}" />

You can also just set an x:Name for MyControl and then the binding looks like:

<Label Content="{Binding DataContext.MyProperty, ElementName=myControl}" />
