Current item in binding

The question i was faced with was how to bind to a current item in an array. Why? I wanted to display the result of the ToString() method on the whole object - it should display something like ‘buy 100 abc.o @ 50′

I had an array (of Equities, but it could have been anything), and some xaml binding to it:

<StackPanel DataContext=“{x:Static EquitiesModel.Equities}“>
<TextBlock Text=“{Binding}“ />
<ListBox ItemsSource=“{Binding}” IsSynchronizedWithCurrentItem=“True“ />
</StackPanel>

That didn’t work because the {Binding} binds to the whole array, and i just needed the current item. It turned out to be some syntax that I hadn’t seen since XPath:

<StackPanel DataContext=“{x:Static EquitiesModel.Equities}“>
<TextBlock Text=“{Binding /}“ />
<ListBox ItemsSource=“{Binding}” IsSynchronizedWithCurrentItem=“True“ />
</StackPanel>

Lo and behold, it used the ToString() method, and I was happy!
