How to access Parent's DataContext in Windows 8 store apps

Question

This is a common situation in XAML based apps (WPF/Silverlight/WinRT).

Answer 1

I just had the same problem. Presumably this is common??

Here is a crude solution that works:

• Bind the Tag property of a top level element to the DataContext

• Bind the property you want via ElementName in nested element, ie

  {Binding Tag.SomeProp, ElementName=gridTop}
