wpf MultiTrigger


Example

A MultiTrigger is similar to a standard Trigger in that it only applies to properties within the same control. The difference is that a MultiTrigger has multiple conditions which must be satisfied before the trigger will operate. Conditions are defined using the <Condition> tag.

<TextBlock x:Name="_txtBlock" IsEnabled="False">
    <TextBlock.Style>
        <Style TargetType="{x:Type TextBlock}">
            <Style.Triggers>
                <MultiTrigger>
                    <MultiTrigger.Conditions>
                        <Condition Property="Text" Value="Pass"/>
                        <Condition Property="IsEnabled" Value="True"/>
                    </MultiTrigger.Conditions>
                    <Setter Property="Foreground" Value="Green"/>
                </MultiTrigger>
            </Style.Triggers>
        </Style>
    </TextBlock.Style>
</TextBlock>

Notice the MultiTrigger will not activate until both conditions are met.
