WPF – How to combine DataTrigger and Trigger?

Question

For anyone else who’s up against this problem, I found a solution that works for me. Of course, I’m still interested to see other interesting answers.

Here’s what I did:

<MultiDataTrigger>
  <MultiDataTrigger.Conditions>
    <Condition Binding="{Binding
      RelativeSource={
        RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem}},
        Path=IsSelected}" Value="True"/>
    <Condition Binding="{Binding IsAvailable}" Value="False"/>
  </MultiDataTrigger.Conditions>
  <Setter TargetName="Name" Property="Foreground" Value="#F00"/>
</MultiDataTrigger>

There’s nothing special about this being a multi trigger though. If you just wanted to style the selected item differently in your data template, you could use:

<DataTrigger Binding="{Binding 
  RelativeSource={
    RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem}},
    Path=IsSelected}" Value="True">
  <Setter TargetName="Name" Property="Foreground" Value="#888"/>
</DataTrigger>
