Actions

Sometimes you want to change some aspect of the widget when a certain event occurs (like a button press). This is what ActionList and Action are for. An ActionList can be coupled to an event and contains – you guessed it – a list of Actions. An action can be used to set the property of an element or to fire a Trigger.

For example:

<VisualBook Name="book" CurrentPage="page1"> 
	<VisualPage Name="page1"> 
		<VisualContent> 
			<VisualText Text="Page 1"/> 
			<VisualButton Padding="3" Clicked="buttonpage1clicked"> 
				<VisualText Text="go to page 2"/> 
			</VisualButton> 
		</VisualContent> 
	</VisualPage> 
	<VisualPage Name="page2"> 
		<VisualContent> 
			<VisualText Text="Page 2"/> 
			<VisualButton Padding="3" Clicked="buttonpage2clicked"> 
				<VisualText Text="go to page 1"/> 
			</VisualButton> 
		</VisualContent> 
	</VisualPage> 
</VisualBook> 

<ActionList Name="buttonpage1clicked"> 
	<Action Subject="book" Attribute="CurrentPage" AttributeValue="page2"/>
</ActionList> 

<ActionList Name="buttonpage2clicked"> 
	<Action Subject="book" Attribute="CurrentPage" AttributeValue="page1"/> 
</ActionList>

In the example above, the buttons can be used to switch between pages.
