Why the need for binding in this context

Question

I am starting WPF looking at How to do o: Getting started with Entity Framework

I'm confused why I need

<ListBox Name="ListBox1" ItemsSource="{Binding Source={StaticResource CustomerSource}}" >

why can't i

<ListBox Name="ListBox1" ItemsSource="{StaticResource CustomerSource}" >

how to find out when i need to Binding. because on the 1st thought, just like I use a static resource in styles

<Button Style="{StaticResource someStyle}"

why not

<Button Style="{Binding Source={StaticResource someStyle}}"

Answer 1

This example assigns a value obtained from resources using the specified key to the Text property:

<TextBox Text="{StaticResource SomeText}" />

In the examples, the Text property is bound to the property of an object extracted from resources using the specified key:

<TextBox Text="{Binding Source={StaticResource SomeObject}, Path=SomeProperty}" />
