CompositeStateTrigger

This trigger will trigger if all or one of a collection of other triggers are active. The triggers used must implement IValueTrigger.

Properties:

• Operator: And (all), Xor (one) or Or (any).

#Examples

Greater than and less than combined to a "between" composite trigger by using an AND operator

<VisualState x:Name="between">
	<VisualState.StateTriggers>
		<triggers:CompositeStateTrigger Operator="And">
			<triggers:CompareStateTrigger Value="{x:Bind slider.Value, Mode=OneWay}" CompareTo="3" Comparison="GreaterThan" />
			<triggers:CompareStateTrigger Value="{x:Bind slider.Value, Mode=OneWay}" CompareTo="7" Comparison="LessThan" />
		</triggers:CompositeStateTrigger>
	</VisualState.StateTriggers>
	<VisualState.Setters>
		<Setter Target="sliderStatus.Text" Value="Slider value is between 3 and 7" />
	</VisualState.Setters>
</VisualState>

Require only one checkbox to be checked by using the XOR operator

<VisualState x:Name="OnlyCheckOne">
	<VisualState.StateTriggers>
		<triggers:CompositeStateTrigger Operator="Xor">
			<triggers:CompareStateTrigger Value="{x:Bind chb1.IsChecked.Value, Mode=OneWay}" CompareTo="True" Comparison="Equal" />
			<triggers:CompareStateTrigger Value="{x:Bind chb2.IsChecked.Value, Mode=OneWay}" CompareTo="True" Comparison="Equal" />
			<triggers:CompareStateTrigger Value="{x:Bind chb3.IsChecked.Value, Mode=OneWay}" CompareTo="True" Comparison="Equal" />
		</triggers:CompositeStateTrigger>
	</VisualState.StateTriggers>
	<VisualState.Setters>
		<Setter Target="selectionStatus.Text" Value="You have selected one value" />
		<Setter Target="submitButton.IsEnabled" Value="True" />
	</VisualState.Setters>
</VisualState>

Trigger when no check boxes are checked by using AND operator on a false-value check

<VisualState x:Name="NoneSelected">
	<VisualState.StateTriggers>
		<triggers:CompositeStateTrigger Operator="And">
			<triggers:CompareStateTrigger Value="{x:Bind chb1.IsChecked.Value, Mode=OneWay}" CompareTo="False" Comparison="Equal" />
			<triggers:CompareStateTrigger Value="{x:Bind chb2.IsChecked.Value, Mode=OneWay}" CompareTo="False" Comparison="Equal" />
			<triggers:CompareStateTrigger Value="{x:Bind chb3.IsChecked.Value, Mode=OneWay}" CompareTo="False" Comparison="Equal" />
		</triggers:CompositeStateTrigger>
	</VisualState.StateTriggers>
	<VisualState.Setters>
		<Setter Target="selectionStatus.Text" Value="Please check one item" />
	</VisualState.Setters>
</VisualState>
