Question

I’ve a ComboBox and a Style for the items. The style is defined by using Style.Triggers in this way:

  <Style>
    <Style.Triggers>
        <Trigger Property="Tag" Value="false">
            <Setter Property="Background" Value="LightBlue"/>
            <Setter Property="Foreground" Value="BlueViolet"/>
        </Trigger>

        <Trigger Property="Tag" Value="true">
            <Setter Property="Background" Value="LightGreen"/>
            <Setter Property="Foreground" Value="Green"/>
        </Trigger>
    </Style.Triggers>
  </Style>

In order to embed this Style I would write next :

<ComboBox>
      <ComboBoxItem Content="xxxx" Tag="true"/>
      <ComboBoxItem Content="yyyy" Tag="false"/>
</ComboBox>

but how I can embed this Style in case I use DataContext binding?

Thanks in advance.

You could try adding a style setter to the ComboBox’s Resources:

<ComboBox.Resources>
    <Style TargetType="{x:Type ComboBoxItem}">
        <Setter Property="Tag" Value="{Binding SomeValue}" />
    </Style>
</ComboBox.Resources>
