Examples
The following example shows two DataTrigger objects that are defined in a DataTemplate. The DataTemplate is applied to AuctionItem data objects (not shown in this example), which have the property SpecialFeatures.
The first DataTrigger is specified such that if the data object has a SpecialFeatures value of Color, then the item is displayed with a DodgerBlue
background with Navy titles. If the data object has a SpecialFeatures value of Highlight, then the second DataTrigger will be active, causing the item to be displayed with an Orange border with a star.
For the complete sample, see Data Binding Demo.
<DataTemplate.Triggers>
<DataTrigger Binding="{Binding Path=SpecialFeatures}">

XAML Values
ZeroOrMoreSetters
Zero or more Setter objects.
A DataTrigger allows you to start actions or to use Setters to apply property values when the data item meets a specified condition.
If there is more than one setter setting the same property in the same setter collection, the setter that is declared last is used.
The Setters property of a DataTrigger object can only consist of Setter objects. Adding a Setter child to a DataTrigger object implicitly adds it to the SetterBaseCollection for the DataTrigger object. EventSetter objects are not supported; only Style.Setters supports EventSetter objects.
