TemplateBinding a RelayCommand - how to?

[williambuchanan2]

Hi all

I have created a 'master page' for my app, and I am inheriting from this page for all the actual (content) pages. This is all working fine.

In the master page I can bind to data from the content page VM by using TemplateBinding:

This also works fine.

However, I can't seem to get my RelayCommands to bind. E.g. if I put this in the master page:

...It doesn't work.

I have seen a suggestion to use BindableProperty, but I can't find an example of that for anything other than basic string binding.

Any suggestions?

Thanks
