WPF Binding Syntax Question

Question

I've seen this syntax show up, and have tried to google for it's definition to no avail; what does it mean when a dp is bound this way?

<Grid>
    <ContentControl Content="{Binding}"/>
</Grid>

I was under the assumption that you have to bind to some property on the DataContext, or another element, but this appears to bind to nothing.

Answer 1

I believe it means you are binding to the root of whatever the binding context is. So if you use this syntax in a datatemplate that is part of some sort of list control, you would be binding to the root level of whatever the parent control (the list control) was binding to.
