DataTrigger Class
Represents a trigger that applies property values or performs actions when the bound data meets a specified condition.
Style, ControlTemplate, and DataTemplate all have a triggers collection. A DataTrigger allows you to set property values when the property value of the data object matches a specified Value. For example, if you are displaying a list of Employee objects, you may want the foreground color to be different based on each Employee's current attendance. In some scenarios it may be more suitable to create a converter or to use a DataTemplateSelector.

ClearAnimation | Clears the animation value of a property |
ClearAnimation | Clears the animation value of a property |
ClearLocalValue | Clears the local value of a property The property to be cleared is specified by a DependencyProperty identifier |
CoerceValue | Coerces and validates the effective property value |
CoerceValue | Coerces and validates the effective property value |
DependencyPropertyChanged | Returns the PropertyChanged event |
GetBaseValue | Returns the base value without animation nor coerce (this never returns IExpression like GetLocalValue) |
GetLocalValue | Returns the local value of a dependency property, if it exists. |
GetValue | Returns the current effective value of a dependency property on this instance of a DependencyObject |
GetValueObject | Returns the current effective value of a dependency property on this instance of a DependencyObject as a boxed value |
GetValueProvider | Gets the provider that returns the effective value for the specified dependency property |
HasAnimatedProperties | Returns true if there is any animated property |
InvalidateProperty | Re-evaluates the effective value for the specified dependency property if necessary If null is passed, a full re-evaluation could be needed |
IsCached | Returns if the value is stored in the cache. If true, the priority is returned in the provider field |
SetAnimation | Sets the animated value of a property |
SetCurrentValue | Sets the current value of a dependency property. The current value is set on the coerce field, without modifying source or animated value |
SetCurrentValueObject | Sets the current value of a dependency property using a boxed value |
SetExpression | Sets the expression to be evaluated dynamically to obtain the value of the property |
SetValue | Sets the local value of a dependency property |
SetValueObject | Sets the local value of a dependency property using a boxed value |
