ToolBarBaseStyle

The default style of the toolbar is not recommended. It should always be used by other styles based on the On.

Case:

<ToolBar Padding="10,6" Header="Demo" VerticalAlignment="Center" HorizontalAlignment="Center">
    <Button Content="Demo" Margin="10,0,0,0"/>
    <ToggleButton Content="Demo" Margin="10,0,0,0"/>
    <CheckBox Content="Demo" Margin="10,0,0,0"/>
</ToolBar>
