I've got a WPF Window, and somewhere there is a ListView where I bind a List<string> to.
Now somewhere in my ListView there is a TextBox and the Content property is set to {Binding}.
But this is the shorthand. How do I write the full binding to bind to itself?
{Binding Path=Self} doesn't work, neither does {Binding Self} (where the latter is a shortcut for the former).
Short answer:{Binding} is not a shortcut for "binding to itself" (in the sense of RelativeSource.Self). Rather, {Binding} is equivalent to {Binding Path=.}, which binds to the current source.
To elaborate: A binding has a source and a path. You can do a "binding to itself", for example, by using
<myUIControl myProperty="{Binding RelativeSource={RelativeSource Self}, Path=x}" /> This, however, sets the source to the control itself, so it will try to access property x of the UI control (rather than property x of the current data context). From how I understood your question, this is not what you want; in particular, it is not what {Binding} does: {Binding} keeps the source as it is (usually the DataContext of some parent element) and binds to the source itself (equivalent to Path=.).
CommandParameter="{Binding ElementName=MyDataGrid, Path=SelectedItems}", it'll pass the SelectedItems to the Bound ICommand. However, null is passed if it's accessed via the ContextMenu. I've tried CommandParameter= "{Binding SelectedItems}", "{Binding ElementName=MyDataGrid, Path=SelectedItems}"` and "{Binding RelativeSource={RelativeSource Self}, Path=SelectedItems}".
another way to bind to self :
{Binding {}} an empty {} binds to the RelativeSource.Self.
