How can I apply multiple XAML styles to one element?

I have a toolkit:DataGrid (from Codeplex).

It is starting to have many different styles:

Do all of these need to be in one big style, is that the only way to do it? Or can I have multiple styles and attach them as I need them? Is there anyway to do this so that you can e.g. swap styles in code?

Styles:

<Style x:Key="CodePlexDataGridSwapper" TargetType="toolkit:DataGrid">
    <Style.Triggers>
        <DataTrigger Binding="{Binding WhichGrid}" Value="Infragistics">
            <Setter Property="toolkit:DataGrid.Visibility" Value="Collapsed"/>
        </DataTrigger>
    </Style.Triggers>
</Style>

<Style x:Key="ToolkitDataGridLayout" TargetType="toolkit:DataGrid">
    <Setter Property="Background" Value="Yellow"/>
</Style>

PSEUDO-CODE:

<toolkit:DataGrid 
    Style="{StaticResource CodePlexDataGridSwapper, ToolkitDataGridLayout}" 
    ItemsSource="{Binding Customers}"/>

You may want to look at the BasedOn property of the Style class. Basically, it allows you to inherit one style from another. The 'child' style will have all of the setters and triggers from the parent one (unless it has setters overriding the parent's ones) plus it will have obviously its own setter and triggers.

Maybe this info will be helpful for you.
