WPF/Silverlight quirks

 

I’ve been trying to share some code between some of my projects, and occasionally struggle to get things to work.

Today, I moved some data binding from my WPF project to my Silverlight project.  The WPF project was using a string indexer on the current DataContext like this:

{Binding Path=.[version]}

This page:

states

Optionally, a period (.) path can be used to bind to the current source. For example, Text="{Binding}" is equivalent to Text="{Binding Path=.}".

Silverlight on the other hand does not like the leading period, but works correctly (as does WPF) when specified like this:

{Binding Path=[version]}

Moral of the Story:  Don’t use leading periods.
