Question

I want to shorten settings bindings

{Binding Source={x:Static properties:Settings.Default}, Path=Password}

To something like

{settingsBinding Password}

By moving part of declaration to global resource dictionary. But it seems that I can’t declare bindings here. Any ideas how to pull this off?

I want at least make it like this

{Binding Source={StaticResource Settings}, Path=Password}

So I don’t have to include properties namespace every time.

To get the first syntax, you have to derive from Binding and specify the source:

public class SettingsBinding : Binding {
    public SettingsBinding(string path) : base(path) { Source = Settings.Default; }
    public SettingsBinding() { Source = Settings.Default; }
}

You can then use: {xxx:SettingsBinding Password}. However, you’ll still have to specify the namespace of this class. I won’t recommend this approach though: bindings tend to be quite verbose but you know what is happening since the syntax is always the same.

To get the second syntax you desire, simply define your x:Static as a resource, eg:

<Window.Resources>
    <x:Static Member="properties:Settings.Default" x:Key="Settings" />
</Window.Resources>

You can now reference it using StaticResource.
