<Button Content="{Binding}"/>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>





{Binding Path=xxx, RelativeSource={RelativeSource Self}}
{Binding Path=xxx, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type typeXXX}}}
{Binding Path=xxx, RelativeSource={RelativeSource TemplatedParent}}
{TemplateBinding Path=xxx}
