We are trying to develop a grid whose AllowEdit property for field settigs depends on some runtime values. It seems that almost any kind of binding fails. We have tried:

AllowEdit="{Binding ElementName=parentUserControlName, Path=IsEditAllowed} "

and 

AllowEdit="{Binding IsEditAllowed}" after setting the User Control's DataContext to "this". 

Both times we get the error:

System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=IsEditAllowed; DataItem=null; target element is 'FieldSettings' (HashCode=15935451); target property is 'AllowEdit' (type 'Nullable`1')

However, if we set the Binding Source to be an x:Static, it works. For example:

AllowEdit="{Binding Path=IsEditAllowed, Source={x:Static  Sample:EntitlementsProvider.Instance}}" it works fine!!!

I know that FieldSettings is just a DependencyObject, not a framework element, but if anyone could explain why this is happening and what workarounds we can do to dynamically set the AllowEdit property in a consistent and extensible manner, please let me know.

Thanks,
